PIC 12-ый День Рождения OpenStreetMap - тортики в Нашуа, США; Бангалор, Индия и Эссен, Германия [^1^] | © Nakaner, Alan Bragg, Jinal Foflia, Softgrow CC-BY-SA 3.0

Картографирование

  • В почтовой рассылке talk-de, Нихил Прабхакар (Nikhil Prabhakar) из Mapbox изложил предложение по картированию и тэгированию запретов поворотов и выездов & удалённым способом. Некоторые люди отвечают в треде; остальные осмеры разогревают попкорн :) План состоит в том, чтобы начать в Штутгарте (где почти нет изображений Mapillary), а также в Вольфсбурге и Берлине (в местах, где находятся Daimler, Porsche, VW, и якобы кто-то ещё). Mapbox также собирается сделать что-то подобное в Канаде.

  • Перуанская команда Mapbox возглавила проведение Mapillary собрания в Аякучо, Уаманга во время которой сделали более 8000 фотографий во время пеших прогулок, поездок на велосипеде и автомобиле.

  • @Mapeadora сообщает о художественном проекте, основанном на воспоминаниях пропавших без вести людей в Мичоакан: "El caminar y los mapas de la memoria" (автоматический перевод) созданы карты на основе различных аудиовизуальных методов, фотографиях сделанных с использованием #Mapillary.

  • Есть обсуждение в почтовой рассылке talk-gb о редактировании границ в округе Ист-Мидлендс в Англии (в частности "районы", где нет никаких местных органов власти, примерно admin_level=10). Там также была значительная критика обсуждений к правкам сделанных по принципу "автоответчика".

  • Мартейн ван Эксил (Martijn van Exel) пишет в своем блоге о перезапуске проекта OpenStreetView (OSV) - теперь этот проект курирует Telenav. Мартейн указывает на то, что приложение OSV может извлекать данные из геосистем автомобиля для геопривязки фотографий с помощью интерфейса OBD2. В отличие от Mapillary, серверные и клиентские части являются свободным программным обеспечением. Этот вопрос остаётся открытым, однако... мы приглашаем Вас к сотрудничеству в создании фотографий и работе над кодом!

  • Pokemon Go работает как идеальный предлог, чтобы собирать точки привязок для коррекции #OpenStreetMap спутниковых снимков, Грант Слейтер (Grant Slater) твитнул об этом.

Сообщество

  • Пользователь Алан Брэгг (Alan Bragg) написал о торжествах в честь 12-го Дня рождения OpenStreetMap прошедших в Нью-Гемпшире.

  • В интервью OpenCage Data c Пеккой Саркола (Pekka Sarkola) был разговор о сообществе OSM в Финляндии, включая их текущую работу и стоящие перед ними задачи.

  • На прошлой неделе проекту OpenStreetMap исполнилось 12 лет. Празднования этого события были по всему миру в Кигали, Дублине, Копенгагене, Москве, Нью-Гемпшире, Лондоне, Бангалоре, Эссене, Теятеяненге и Тунисе.

  • Lambertus является единственным человеком, с полными правами администратора на OSM форуме и он по-видимому находится вне зоны доступа. Поэтому, идёт обсуждение в списке рассылки, о необходимости рассмотреть вопрос по созданию нового форума. Некоторые из обсуждаемых проблем были о сохранении существующих данных.

  • В проекте Паскаля Нейса (Pascal Neis) Какой у вас вклад в проект OpenStreetMap? теперь также имеет тепловой календарь активности картирования (похожий на календарь активности у github)!

Импорты

  • Рабочая группа по данным (DWG) откатила не обсуждённый импорт от Facebook'а из-за плохого качества автораспознования улиц в Египте. Подробнее можно прочитать обсуждение в комментариях к пакету правок сделанного отката.

Фонд OpenStreetMap

  • Рабочая группа по данным (DWG) ищет преводчика с английского на китайский.

  • Свен Гиггас (Sven Geggus) считает что из-за того что membership@osmfoundation.org использует услуги электронной почты Google, то из-за этого отклоняет электронные письма от его сервера как "спам", это может быть причиной отказаться от участия OSMF. (автоматический перевод)

События

  • Мероприятие BarCamp Takoradi 2016 состоится 27-го августа 2016 года в Такоради, Гана в месте, которое ещё предстоит определить. Темой этого года является "Профессионализм в сфере развлечений и предпринимательства".

Гуманитарный OSM

  • В проекте Рамани Хариа используя навигатор Garmin & и приложение Mapillary провели картирование города Дар-эс-Салам, Танзания. Так же эти снимки улица могут быть использованы многими способами, в том числе для создания виртуальных прогулок и для исследований местных достопримечательностей, создания маршрута по точкам интересов, и для других применений.

Карты

  • Маркус Рейтер (Markus Reuter) создатель сайта Netzpolitik.org вносит в проект OpenStreetMap новое применение Надзиратели под надзором. Это интерактивная карта всех камер наблюдения, которые ещё до сих пор не картированы.

  • Создан, основанный на Mapbox GL, стиль OSM свободный от OpenStreetMap, является полностью свободным, чтобы использовать его как угодно и даже на своём сервере. Это ответвление от стиля OSM Bright созданный на основе свободных источниках с миссией отображения чёткого элегантного дизайна карты подходящего для повседневного использования.

  • Компания Stamen запустила охватывающее весь мир, основанную на OSM карту со стилем Terrain. Этот репозиторий публичный и компания Stamen приглашает к совместной работе на ним.

  • Если ваша программа, использует тайлы сервера со стандартным стилем карты (например tile.openstreetmap.org), и она не отправляет HTTP реферер, то она в будущем будет работать с пониженным приоритетом, как сообщил Пол Норман (Paul Norman) о списке рассылки для разработчиков. Это сделано, для того чтобы уменьшить нагрузку на сервера. Перегрузка была вызвана, в частности, сайтом FastPokeMap

  • Лукас Мартинелли (Lukas Martinelli) спрашивает как в действительности выглядит Антарктика? Ему Мартин Райфер (Martin Raifer) указал на старую статью (от Кристофа Хормана (Christoph Hormann)).

switch2OSM

  • Один из известных сайтов для междугородных прогулок в Бельгии в настоящее время использует OpenStreetMap.

  • Ник Дойрон (Nick Doiron) обнаружил карту OpenStreetMap в Дубае, ОАЭ.

  • В городах Гданьск и Ольштен можно следить за положением трамвая на карте с подложкой OSM.

Открытые данные

  • Кристоф Хорманн (Christoph Hormann) проанализировал записи ALOS AW3D30 Японского агентства аэрокосмических исследований. ALOS AW3D30 является глобальной цифровой моделью рельефа опубликованной под свободной лицензией.

  • Майкл Хорз (Michael Hörz) из института Гёте подводит итог прошедших в последнее время обсуждений Открытых Данных в Германии. Здесь стоит отметить проект Mapnificent основанный на OSM базе.

  • Компания IBM объявляет о сотрудничестве с Mapbox в деле анализа геоданных или “картирования” для бизнеса путём интегрирования с системой аналитики Watson и тем самым открывает новый уровень аналитики для всех.

Лицензии

Программное обеспечение

Программирование

  • Компания Mapzen сделала подробную статью о своём сервисе маршрутизации Valhalla и как он учитывает специфичные для стран ограничения для пешеходов. Для этого, используется библиотека Mjolnir создающая данные для маршрутизации.

  • На сайте Geofabrik сделали пересмотр состав своих бесплатных шейпфайлов. В переходном периоде будут предлагаться обе версии, но позже только новая. Свободные шейпфайлы были доработаны, чтобы включать в себя пешеходные и велосипедные дороги.

  • Пользователь Zabot, который участвует в мероприятии "Программируем летом с Google", пишет о том как в настоящее время OSM2World делает отражения на окнах зданий.

(автоматический перевод)

  • Google поощряет своих пользователей, чтобы они добавляли местные знания своей местности, такие как часы работы, уровень шума и т.д., чтобы помочь сделать лучшие карты.

OSM go Earth - Fragen

Es gibt auch diese Woche etwa zu berichten ;-) Es geht voran, zu langsam und doch zu schnell: Zu schnell geht es, weil meine Begeisterung mein Restleben und den Nachtschlaf beeinträchtigt. Zu langsam weil das Testen mit Javascript eine Qual ist per „Console.Log“, am Smartphone gar nur „alert“. Gibt es ein gutes Framework mit Beakpoints?

OSMgo Greenwich

Was hat sich getan: Erst muss ich mal erwähnen, dass ich schon lange mit einem Freund zusammen 3D-Javascript bastle. Martin hat mir mal eben den Download mit AJAX und das Scannen des OSM-JSON gebastelt. Da konnte ich dann meine „new Node“ usw. eingehängt – schon wurde, statt ein paar Test-Daten, ein echter Ausschnitt aus OSM sichtbar, siehe Bild-Kommentar zum letzten Post. Es waren erst mal nur Highways und Buildings. Für die Tag-Auswertung war ein Konzept notwendig; jetzt gehen schon einige Tags mehr (leisure, waterway, landuse) aber immer noch rudimentär. Die „higway“s verschieden breit, Farben später. Bei „power“ war es erst mal Spaß, an jeder Node einen kleinen Mast auf zu stellen und diese dann mit Leitungen zu verbinden. Das auch „building“s zusätzlich „power“ haben können zeigt, dass die Main-Typen eine Priorität haben: Wenn das Tag „building“ da ist, ist „power“ ein Sub-Typ bzw. Detail-Info zum Gebäude. Gibt es eine Beschreibung der Logik des Renderns, als Text oder Pseudo-Code?

Lustig war auch, dass mein Code gleich den Fehler Tag-Array-Länge-Null geschmissen hat. Da ist tatsächlich ein recht lange Way ohne Tags in meiner Nachbarschaft. Darf ID das? Kein Felhler: die Tags sind an der Relation zu der der Way gehört: Ein Wasserschutzgebiet.

Meine 3D-Darstellung ist eher plakativ als realistisch, um die Flächen-Typen zu verdeutlichen. Es gibt Kartenstiele, die Farben etc. festlegen. Eine habe ich gefunden. Wäre es gut, wenn ich die einlese und alles „genauso“ darstelle? Gibt es fertigen Code, um diese Dateien ein zu lesen?

Demnächst will ich mir bei OSM2WORLD (und Cartagen) ansehen, wie die das machen, um so zwischendurch auch den Renderer zu verbessern. Von OSM2WORLD habe ich einen YouTube-Vortrag gesehen, sympathischer Knabe :-)

Auch GPS ist inzwischen angezapft; so wird schön die eigene Umgebung als dargestellter Abschnitt ausgewählt. Noch sind die Lauf- und Zykluszeiten harmlos. GPS und Overpass-Abfrage dauern da länger. Zum Testen ist es oft besser, GPS und AJAX durch Dummies zu ersetzen, läuft schneller und erzeugt keinen Stress für Overpass, das nicht immer schnell läuft. Es ist ja auch nicht als „Arbeits-Server“ gedacht. Für das Gaming/3D-Surfing wird irgendwann eine eigene Server-Instanz notwendig sein. Ob Overpass der richtige Vektor-Tile Server ist? Gibt es bessere? Von OSM selbst?

Wie bei 2D-Karten üblich kann man auch hier beim 3D-Rendern zusätzliche Infos als „Layer“ einbauen, als Erstes „Keep Right“. "kort.ch“ macht das ja auch (in 2D). Bei kort kann ich das API und den ganzen Ablauf erkunden, sogar in Javascript! Welche Layer sind noch gut? Wikipedia, GeoCashing, OpenStreetView, welche Wünsche habt ihr?

Eine Gamification ist (fast) auch nur ein Layer. An einem Samstag habe ich ein simples Game eingebaut: Um die GPS-Position, an der der „Spielers“ OSM go startet, schwebt über jeder Node eine Kugel. Kommt man näher als 15m wechselt sie die Farbe, schwebt hoch und verschwindet. Und man bekommt 100 Punkte :-) Dazu reichen 65 Zeilen Code; natürlich alles roh und ohne Luxus. Ich habe aber mal zwei Level-Intros erdacht:

  • Du bist Packman! Schnapp dir all gelben Punkte um zum nächsten Level zu kommen.
  • Das Reich der Feen kannst du nicht sehen. Die Kamera deines Smartphones sieht mehr! Deine Fee hat goldene Kugeln für dich verteilt. Geh hinaus und suche sie alle, dann wird die Fee sich bei dir melden. Gehe nicht auf die Straße! Die Kugeln spüren dich und kommen zu dir.

OSM go Packman

Hier kann es jeder ausprobieren: (www.ac1000.de/osm)

Ich suche Pilot-Tester! Wer macht mit?

Ich habe nur mit iPhone Notebook getestet! Was geht bei Android? Es sind noch einige Render-Fehler enthalten, da geht’s hin wenn die Control geht.

  • Beim Smartphone sollte sich beim Drehen die Umgebung 1:1 grob wieder finden (plus Kugeln über den Nodes). Und beim Laufen sollten sich OSM-Darstellung und Realität synchron verschieben, soweit GPS genau ist. Auf zum Punkte sammeln!
  • Am Notebook kann man mit der 1. Maustaste drehen, mit der 2. Sliden und mit dem Rad zoomen.

Und wenn garnichts geht, neben den Bildern gibt es hier auch ein kleines live Video.

Mit GPS, JSON und "Packman" ist das „proof of concept“ eigentlich getan, jetzt müssen die vielen Feinheiten dazu, damit es sich ein Programm/Spiel nennen darf. Und die Grobheiten: Bedien-Funktionalität, Level usw. Zunächst bin ich dabei aus diversem Code einen eigenen Control basteln müssen. Bisher ist das Handling noch dürftig. Es soll ja mit Key, Maus und Touch genehm; am PC, Tablett und Smartphone; ohne und mit 3D-Brille; Bewegung frei oder per GPS; laufen, schweben, fliegen übergangslos hoch bis es in eine 2D-Ansicht über geht. Der Anwender soll selbst entscheiden, wie er Packman spielt oder Hausnummern sucht. Er soll auch einstellen können, bei welchem Zoom-Level was eingeblendet wird.

Eine 3rd-person ansieht wie bei Pokemon GO wird es natürlich auch geben. Aber keinen Körper-Editor sondern eine Symbol-Figur. OSM hat kein Plüsch-Maskottchen, oder? Eine Symbolfigur die jeder kennt, das für bewegen über die Erde steht. Ich denke da an einen lustigen Zugvogel. Andere Vorschläge?

House of Dreams

This is a small meditation upon the fragility & fleeting nature of life and an encouragement, from one who is becoming old, to fix your gaze upon what you can be & never to stop.

house of dreams

I found a couple of houses on my last survey that appeared to be abandoned. The one above was particularly poignant because of it's 2nd floor portico; I could imagine the owners and their guests in days past, standing with drinks on hot, balmy summer evenings, gazing across the vista of the fields of Marshall Hill as it fell away below them (Marshall Hill is one of the taller hills in Nottingham, and the houses that now cloak the hill are worth many millions of £ GBP). Today, the house is unloved & ill-kept, hedges, bushes and trees growing to the skies and hiding the house from view most of the time.

So how does such a fine house end up alone & unloved? I know nothing of this house, but did discover the story of a large area of Brownfield land near Porchester Road. It was prime development land, but the person that owned it was now without family & ensconced within a Residential Home for those with dementia. My father had vascular dementia following a heart attack so I know that well. The typical lifetime for someone resident within a Home is 2 years, but it also may be 2 decades. In the meantime, if they have no-one else their property rots. It seems to be a common issue, if my experience across the last 5 months is anything to go by.

I'm sorry that this turns out a touch morbid, but it does seem that in mapping all human life is there.

English Eccentricity

I say: let's celebrate the eccentricity that lies at the heart of the English character.

flowerpot man

This is the Flowerpot Man on the roof that I spoke of in my earlier Diary entry. I was worried about rain then, but it was spotting all day today (and raining hard by tea-time) so why worry today? However, it turned out that the householder valued his privacy, had a lock on the gate & no bell. I needed to get higher to get a good photo & could not (or at least, not without breaking in). My cheap smartphone has a decent camera but only a digital zoom (which I did not use), so the man is very small.

The next picture has another of my favourites, which is Gargoyles, in Marshall Hill Drive.

gargoyle1

The Ecclesiastical Boundary runs down Marshall Hill Drive, up Simkin Avenue (the next street on the other side of the table in the road) then up Donkey Step (which is just to the right of the lamppost and which, to my mind, that closest Gargoyle appears to be looking at). Here is another view of the same 3 gargoyles from the other side:

gargoyle3

One curiosity is that Marshall Hill is no longer on the map, and only on the old Bartholomew map; I'm looking for a way to add it, although I'm waiting first to see if any of the locals remember it, or use it, any more.

Sarah Mildred Long Bridge Closed permanently (ME/NH)

(copy of post to talk-us)

Breaking news - pardon the pun -

The lift bridge on US 1 Bypass between Portsmouth NH & Kittery ME is stuck in the up position. Permanently.

It initially stuck "down", but they managed to get it up one last time for a ship that wanted to exit port, by some expedient, but that killed it. It was scheduled to close permanently, to be scrapped, in just 10 weeks (November, at end of tourist season), with the under-construction parallel replacement-span to bear the same name due to open Spring 2017.

NHDOT & MeDOT considered fixing it one last time but after checking if the jam, a problem they're rather too familiar with, was a hard or easy jam, the cost for the short remaining life was deemed excessive.

Reference MDOT SML

After waiting a day for a local to do so (after official declaration that permanent closure was effective immediately), I have applied change-set 41726297 to mark the bridge's 3 ways -

  • access=no foot=official bicycle=no
  • note=CLOSED - mid section of bridge is a lifted roadway stuck in up position 2016-08-22. Permanently closed 10 weeks early, will not reopen. new bridge due to open spring 2017.
  • (except: foot=no, level=4 on center span stuck in UP position; if you're official enough to get up there, you don't need OSM to find it! )

For the under-deck​ rail-crossing Way 150771571, v11 I only gave it the same 'note' above, it didn't have access= routing tags, it's rail (and for special federal trains only these days i hear).

I have also added map notes, one closed, referencing the above change-set on existing center span, and one open, at approximate offset of the new span, referencing the MDOT project page as a TBD next spring.

I'm open to constructive criticism on better tagging ... or fix it and share why ; e.g.,

  • Should we split the nodes where ways at level=2 joins level=4 ? I could argue that ...
  • Maybe splitting the rail way at the lift towers; if so, its center span would be level=3, below center lift level=4, above the approach span highway at level=2
  • I considered either foot=no or access=official for the approaches. Having seen routing try to jump from way to way if close enough, i decided foot=official was fair. (Knowing as I did someone who died in an ambulance when this bridge was up, i don't want to route anyone that way accidentally ! Never again.)

I note the retractable section of railroad deck that allowed low boats to pass one of the side spans was never mapped. Neat feature.

( Lest I be accused of strictly armchair mapping, as a once-and-future Maine-iac, I know that bridge well by its old official name, "Interstate Bridge" which is ironic as it was never an Interstate System bridge officially though it used to connect two I-95 segments. Originally was 3 rather narrow lanes ... was hell with trailer mirrors mounted in 1970s! I was planning on making extensive use of it in just a couple weeks, while dragging the GPS around the harbor defenses of Portsmouth harbor. I'll be reloading the Garmin's NewEngland card after this change-set percolates through ! I hope to add my Maine retirement home to the map in a year or three, but first we need to build it ... )

Happy to Meet You

I feel like this myself at times...

To see you nice...

This was the greeting that met you on coming through the side-entrance at a bungalow on Hallam Road but was not the best I saw yesterday (Thursday afternoon, 25 August). That was a Flowerpot man on top of a house roof in Pilkington Road (no, really). However, I was worried about the delay that obtaining agreement to photograph it might take. It had been pouring down with rain earlier on & I was worried about further rain soon (it never happened). I'm going back to the house another day, so maybe will be able to feature it soonish.

Weekly Roundup of Edits

Following were some of our observations on the edits made on OSM for this week. The associated changesets have also been mentioned for your kind reference.

  • Camp sites that were'int present was being added in this changeset as opposed to what was seen on the satellite imagery. Also, this changeset neither had a comment nor the source of information.

  • Coastline of an island was deleted; Changeset link

  • ATMs, artwork and campsites were being added all over the map; Changeset link 1,2,3.

  • Amenities such as town halls, supermarkets and unclassified, secondary roads were being deleted ; Changeset link 1,2,3

  • In yet another case, the user was found adding tourist spots with improper and arbitrary names; Changeset link

  • Here, the user was found deleting a lot of trunk, primary, secondary, tertiary roads and amenities. In some of his other changesets he was found tampering with the disputed border between India and China; Changeset link.This user was subsequently blocked by the DWG and all the changesets were reverted.

An attempt to address these issues have been made both, by the community and us by leavings comments in the respective changesets.

The previous week's review can be found HERE

Happy mapping. Let's all make OSM the best map ever.

Thank you all so much!

  • Logo Сломанные линии на ОСМ картах в Филлипинах Fault [1]

Картографирование

  • Университет штата Вашингтон хочет импортировать пешеходные тротуары в ОСМ. Поэтому они предлагают обсудить новую схему тэгирования представленную в предложениях, которая предполагает расширение на основе существующих схем. Там есть много критики в списке рассылки, и только ограниченные ответы насчёт их предложения, больше информации в обсуждениях проекта в вики.

  • Квартальная задача «школы» в Великобритании продолжается - и даже получила существенное ускорение от Христиана Ледермана (Christian Ledermann) в виде "найди школу рядом с тобой и нанеси её на карту" с помощью его приложения.

  • Манохар (Manohar) из Mapbox пишет о добавлении ограничений поворотов в Канаде и делится инструкциями, как это сделать.

Сообщество

  • Мы можем с гордостью объявить о появлении Логотипа OSM Латинской Америки. Большое спасибо @mapanauta and @jbtschopp

  • Карито Тенорио Паломино(Karito Tenorio Palomino) и редактор Еженидельника ОСМ Эдит (Edith Quispe) обучили 100 школьниц во время мастеркласса по OpenStreetMap проведённого во время Женщины в научном лагере 2016. Участники мероприятия были познакомлены с ОСМ, обучились как вносить свой вклад с помощью редакторов iD/JOSM, а также придумывали идеи использования карт.

  • В блоге OpenCageData опубликовано интервью с Намиталой Гертруду (Namitala Gertrude) о работе проекта OpenStreetMap в Замбии.

  • На карте отображено распределение участников, активных в Телеграмм группе OSMLatam.

  • Том Ли (Tom Lee) (работающий в Mapbox) изложил свои мысли по поводу статьи в зажигательном блоге Майка Мигурски (Mike Migurski).

  • В еженедельникеОСМ уже сообщалось ранее о картографической деятельности ирландской группы ОСМ и особенно пользователя Dacor в Лесото. В настоящее время их деятельность отмечена во время картопати в посольстве Дублина Королевства Лесото.

  • Кто-то создал Slack канал для проекта ОткрытыхИсторическихКарт (OpenHistoricalMap). Разделение средств связи между почтовой рассылкой форумом, твиттером, группами в Телеграмм и теперь ещё и в Slack делает темп общения вялым и более сложным для новичков. А также и для отслеживания событий редакторами еженедельникаОСМ. ;-)

  • Мартин ван Эксил (Martijn van Exel) инициирует усилия по улучшению OSM данных в Айдахо с помощью (как писал Майк Мигурски (Michal Migurski)) "ремесленников" картографов. Данные, созданные местными добровольцами, а также данные, полученные во время обследований доступны для работы по улучшению этой области на карте OSM.

  • Томас (Thomas) (malenki) объявил о "тайм ауте" в активности в проекте OpenStreetMap. Успехов и спасибо за картографирование!

Фонд OpenStreetMap

  • Для награждения наградой ОСМ необходимы номинанты в шести категориях - За вклад в инфраструктуру, За инновации, За важные слова, За лучшее картирование, За развитие сообщества, Премия имени Ульфа Мёллера.

  • Пользователь SB79 напоминает всем о Elbe-Labe-Встрече которая будет проходить с 7 по 9 октября в Дрездене (Германия).

  • ИНТЕРГЕО, торговая ярмарка по теме геодезии и геоинформатики будет проходить в Гамбурге между с 11 по 13 октября.

Гуманитарный OSM

  • В газете Гардиан вышла статья о проекте MapSwipe, и там почти (но не совсем) удалось избежать упоминания Pokémon Go.

  • Энн Мей Чанг (Ann Mei Chang) сообщает об американской инициативе против распространения малярии. Для эффективной защиты, имеют важное значение хорошие карты. Например, ОСМ группа Юные Картографы вносит свой вклад в Мозамбике.

Карты

  • Хорошо известные руководства Одинокая планета запустили приложение с картами доступными в автономном режиме с помощью мобильного MapBox SDK.

  • Настольное приложение, Карты GNOME, перестало работать когда MapQuest остановили неограниченный доступ к своим тайлам. Сейчас карты GNOME начали использовать тайлы Mapbox (по видимому одной из важной особенностью было наличие названий с использованием латинского алфавита, даже для мест изначально не имеющих такого).

  • Уолтер Нордманн (Walter Nordmann) жалуется что в течение нескольких недель немецко-французская граница была повреждена вблизи Люксембурга на картах UMAP. Он думает, что это выглядит так, как будто "никого это не беспокоит".

switch2OSM

  • Информационный портал Морской Трафик теперь использует OpenStreetMap чтобы показывать недавние местоположения судов. (Из твиттера)

Лицензии

  • Из-за дискуссии о копировании стиля карты Mapbox Streets (в JSON формате для Mapbox GL) между Mapbox и проектом OSM2Vectortiles. Стив Гиффорд (Steve Gifford) пишет о таблицах стилей для Mapbox GL в инструментарии WhirlyGlobe версии 2.5. Формат описания стилей для слоёв появится в ближайшее время. Как сказал Стив: "Это не круто, но будет мило если будет поддерживаться OGC стандарт."

Программирование

  • Проект Door2Door, стартап базирующийся в Берлине, работающий в области общественного транспорта, примет на работу разработчика программного обеспечения ГИС.

  • Пипин Шоен (Pepijn Schoen) описывает как он создал Docker контейнер, для отображения маршрутов на карте, там где он путешествовал по железным дорогам.

Mappa Mercia (UK Midlands)

Birmingham roundabout amongst the most dangerous in the country

Yesterday the Birmingham Post (our weekly city newspaper) carried a story about the number of accidents on major Birmingham roundabouts. The recently reconfigured roundabout at Bordesley Circus, with an accident every 20 days over the previous six years is the second most dangerous roundabout in the country. That’s a total of 105 accidents.

The Post chose to illustrate its story with graphics based on OpenStreetMap data; showing the site of accidents. Without attribution it has to be said: we’ve already contacted the editor pointing out our attribution policy

The story went on to list the next five most dangerous roundabouts in the city, each with its OSM-based diagram of accidents.

Its always good to see our data being used. Even better to see it being attributed!

"OpenStreetMap.org User's Diaries"

Reported on OpenStreetMap Training (22-24 August, 2016) at Dhaka College, Bangladesh

OpenStreetMap(OSM) is the greatest invention of modern mapping system in this digitalized world. It is a great source of open data. It is more helpful and informative from any other online Map. In this MAP we get specific data. It is very helpful for peoples. By this map anyone can get information about his queries. Anyone can upload data and also can use data in their necessity. It is also helpful for the organizations that help vulnerable peoples. In this map we get the information about vulnerable area, way of passing, important point, water point etc. that is necessary for any kind of search and rescue operation in disaster. In this map data is free, so it is granted by everyone. It is easy to upload information in this map so anyone can contribute with the information from anywhere, anytime. OSM data is helpful for Vulnerable Capacity Assessment (VCA). By using this data different NGO, Government and International organizations can continue their relief operation. It is also helpful for research work. After all we can say, OSM data is very helpful for people for society as well as country. OSM data is very helpful for disaster risk management. In this map we get the data about identification of vulnerable places, way of passing, important key indicator as building condition, material, and structure by research this information govt. or relevant authority will identify the vulnerable places and take necessary steps to reduce the vulnerability, to reduce the damage of any kind of disaster. By using this data Bangladesh Red Crescent Society or this type of voluntary organization or Government organization like fire service, civil defense can plan their search & rescue operation.

I am Sawan Shariar from Bangladesh. I am an OpenStreetMap mapper and working since 14th May, 2015. I have done field level Mapping using GPS device, FieldPaper, OSMAnd, OpenMapKit, OSMTracker, Mapillary, MapSwipe and OSM Contributor. I upload data by using ID Editor, JOSM Editor and Potlatch 2. My complete mapper profile can be found at Sawan Shariar. I have done mapping for "Data for Action Project" and assisted in various OSM training with Bangladesh Red Crescent Society and continuing as a Super Mapper. I successfully completed The "Training for Trainer: OpenStreetMap" Training from Bangladesh Red Crescent Society supported by American Red Cross.

I am a volunteer of Bangladesh Red Crescent Society. And now I am working as Youth Chief of Red Crescent Youth, Dhaka College Unit (RCY,DCU). After successfully completed the Training for Training: OpenStreetMap I realize that, this training will be very useful for the volunteers of RCY,DCU. So I tried to understood my teachers and principal, how it’s effective and importance. And I successfully done that.

Red Crescent Youth, Dhaka College Unit is a voluntary organization, it started its journey in 2 may, 2004. It’s motto is serve the people. In its long journey it conducted many search & Rescue operation in different disaster. When the authority learn about the necessity and importance of OSM in disaster. They decided to arrange Training for the volunteers. In 22-24 August 2016, OpenStreetMap (OSM) training was conducted at Training room, Red Crescent Youth, Dhaka College Unit. This training was started sharp at 09.00am and it solely attended by the 26 volunteers of Red Crescent Youth, Dhaka College Unit.

Opening session was presided by Sheikh Sabbir Ahmed, Associate Professor of Dhaka College and Teacher In Charge of Red Crescent Youth ,Dhaka college Unit. As Chief guest there was present the pioneer of OpenStreetMap in Bangladesh Ahasanul Haque, Geospatial Data Management Consultant in World Bank Bangladesh. He gave his pleasant speech about OSM that inspires the Participants. Then the training Session started. The Training was conducted by Sawan Shariar, Atikur Rahman atik and Manjurul Islam and assisted by Diluar Jahan & Atikul Islam.
On the first day training session was divided into 4 sessions, which were

  1. Introduction of OpenStreetMap

  2. Introduction and use of ID Editor in OSM

  3. Introduction and How to prepare Field Paper.

  4. Field work: Collect data using field papers

The practical session started with opening an account in ID editor, a web-based mapping tool and it always needed to be connected to the internet. Then all the students made their own OSM account using ID editor before the training session. The participants were learned how to configure the background layer and how to do basic edit with ID editor along with knowing additional information and custom tags. Data that used in editing in this session was specially the home address of the individual participants.

After the lunch break, the participants were introduced to the Field Papers website. The participants were taught how to create a printable map Atlas for anywhere in the world. They were learned how to print and add notes to the field papers. At last participants were paired into 13 team and sent to field for data collection. The first day of the training session was ended with the horizontal development with the shores of knowledge as well as the fervent smiling faces of the participants.

Second Day the training started with its full swing at the same place at the same time like the day before. The Second day of the training, the practical session divided into 5 sessions, which were-

  1. Review on previous day.

  2. Edit Upload data of previous day’s field work.

  3. Field work: Collect data using field papers

  4. Introduction and the Use of JOSM in OSM

  5. Upload collected data using JOSM Editor by participants.

The Sessions started with review on previous day works and upload data of previous day’s field works. After that, participants went outside again to collect data by using field paper. After the lunch break, the participants were introduced with JAVA Open Street Mapping (JOSM). They learned about interface of JOSM, activate imagery providers and upload data. After that they learned how to use JOSM offline by saving the important files for editing. And finally the second day’s training session ended up with uploading their collected data by using JOSM Editor.

Third Day the training started with its full swing at the same place at the same time like the first day. The Third day of the training sessions divided into 6 sessions, which were-

  1. Review on previous day.

  2. Field work: Collect data using field papers

  3. Edit & Upload their collected data

  4. Introduction in HOT &Teach Tasking Manager.

  5. OSM android apps & how to collect data by using it?

  6. Feedback & closing ceremony.

This day’s session started with Review on previous day works and upload data of previous day’s field works. After that participants sent outside to collect data by using field paper and after lunch participant edit & upload their collected data.

In the second session , the participants have instituted by the Humanitarian OSM Team collaborative mapping tool which is known as Humanitarian OpenStreetMap Team (HOT) Tasking Manager and Teach Tasking Manager. Participants also taught how to edit the maps both in teach and hot tasking manager not only editing by ID editor but also editing by JOSM. After that participants were introduced by many maps editing Mobile apps. The mobile apps are Mapswipe, OSM Tracker for Android, Map ME, Vespucci, Mapillary and OSMand.

The training was successful. The credit goes to The Honorable Principal Professor MD. Muazzom Hossain Mollah of Dhaka College. I am grateful to Sheikh Sabbir Ahmed & Farjana Islam, Associate Professor of Dhaka College and Teacher-in-charge of Red Crescent Youth, Dhaka College Unit. I am also grateful to Ahasanul Haque, The Pioneer of OpenStreetMap in Bangladesh and Geospatial Data Management Consultant in World Bank Bangladesh.

About us

  • When reporting on OpenStreetView last week we made a mistake. Thank you Jochen for pointing it out. (Deutsch)

Mapping

  • Voting on the proposed tag healthcare=midwife started on August 22nd and closes on September 5th.
  • More on the ‘MAPS.ME’ – a new application version is rolled out by them which includes an extra “name:<language>” key (also a Github isssue is filed on the same).
  • In a blog post, Seth Fitzsimmons explains the technical details of ‘Portable OSM’.
  • Joost Schouppe reported about ‘open’ road data in Flanders (Belgium) and how it can be used in OpenStreetMap.
  • Mapbox mapping employees have lately been looking at possibly “suspicious” change sets. User manoharuss asks in his blog about how long it is suggested to wait for an answer in the changeset discussions. His colleague nammala listed questionable changesets in his user’s blog on OpenStreetMap.
  • Christian Quest wrote a bash script that allows him to copy and georeference a Linux-mounted iPhone’s Mapillary images via exif data to use them directly in JOSM before uploading.

Community

  • Escada interviews Jorieke Vyncke from Belgium, as this month’s “Mapper of the Month”.
  • “OpenStreetMap at the Crossroads” is the subject of Laura O’Gradys message on the Canadian OSM talk mailing list describing how communication stopped between her a “local craft mapper” and a “robot Mapper”. Laura refers in her e-mail explicitly to the blog post OpenStreetMap at the Crossroads from Jonathan Crowe who qualifies and discusses the statements of Migurski.

Imports

  • This Minneapolis Maptime announcement caused a certain amount of amusement in some quarters (” … techniques bringing in large open source datasets to Open Street Map … No previous Open Street Map experience is necessary”). However Minneapolis did get 3 new local users last week, and a few more further afield.
  • The OSM versus TIGER Battle Grid has been resurrected, now with Stamen tiles in the background. The Battle Grid points out areas where recent USA Census TIGER data is different from OSM data. This usually means OSM data needs to be updated (but sometimes it means TIGER is worse than OSM). 🙂 If you have not tried it, go to http://184.73.220.107/battlegrid and solve a few squares.

OpenStreetMap Foundation

  • Following some issues with its current bank, OSMF is on the look out for an alternate bank which will provide the board more flexibility in terms of multiple currencies and international access. Frederik Ramm asks for advice.

Events

  • The State of the Map will host a social event for the participants of the conference on September 24th.
  • On Friday, 26 August 2016 an interesting Mapathon will take place in Colombia from 08:00 AM to 12:15 PM. Targets among others are highway=tertiary. This Mapathon is aimed at a group of Spanish speaking students which are part of YouthMappers, students from Universities in Colombia and the general Colombian OSM community. There are awards up for grabs (including field trips and tablets) in multiple categories.

Maps

  • [1] Lukas Martinelli published osm-activity, a global heat map of OpenStreetMap where one can see the number of changes made to OSM in each tile dating back to 2008. The sources are available on Github. Lukas Martinelli says: “When you click on a region a timeline is displayed and you can see imports and long-term trends.”
  • Opentopomap doesn’t update anymore? Stefan Erhardt is looking for help. (Deutsch) (automatic translation)
  • The New Cloud Atlas is a special map for telecommunications infrastructure presented by Tim Waters on the talk mailing list and in his blog.
  • Paul Norman asks how “handling the need to do both cartographic and technical review”.

switch2OSM

  • ImmobilienScout24 a German property website shows data from Wheelmap showing wheelchair suitability of nearby POI. Data are provided by Sozialhelden and thus from OSM. However, the base map is still the one from a competing map provider.

Licences

  • Due to the confusion about Mapbox vector styles, Simon Poole asked Mapbox about 2 weeks ago to clarify their licences.

Software

  • Mapbox has now acquired Human, a company which developed an app focusing on activity tracking.
  • The latest version (6.3.2) of Maps.me offers several improvements, such as considering gradients in bicycle routing, and a clearer map layout.
  • The OsmAnd developers work on a new rendering engine with multi-threading.

Programming

  • Mapz provides two job vacancies for “people with a penchant for OpenStreetMap”.
  • Frederik Ramm proposed in a pull request on GitHub to reduce the maximum size of change sets from 50,000 to 10,000 objects. He received only affirmative responses.
  • Want to install Overpass yourself? It’s really not that difficult 😉
  • If the indexes of your PostgreSQL database are too large, may be pgindexrebuild by Rory McCann can help.
  • Weather Decision Technologies released on Github a Java library for processing Mapbox vector tiles under the Apache License.

"OpenStreetMap.org User's Diaries"

Adding house numbers of one town from cadastre to OSM and survey verification

Why and how

In Slovakia we have electronic cadastre available and it contains buildings in vector format with building conscription numbers (in our country it is conscription number Key:addr:conscriptionnumber ). These information are public and we have some smart OSM users that created a conversion possibility to get it into OSM maps KaporSKAddress#Conscription_numbers_import .

I have decided that I will use available method that takes cadastre house numbers and assign them to OSM map buildings in my town and then I will verify how correct these data are. Goal was:

  1. have houses with numbers searchable in OSM. It was found to be helpful also for ambulances in case of emergency to have searchable map!
  2. to keep OSM map up to date - to reflect reality which is goal of OSM
  3. by curiosity to see how precise are cadastre data

My town has approx. 1600 inhabitants and 632 houses plus some garages, cottages and huts. Town has approx. 10 streets.

Fast part

Building shapes are already imported into OSM for most of Slovakia for some time. Though, importing conscription numbers can't be fully automated and it can be tricky. Jose helped me with import process (thank you!) and it took less than half a hour; This was the first commit.

Slow part

Import process shown that in about 15 cases different houses had the same house number. I decided to resurvey whole village to verify all the house numbers (because of reasons 1-3 above).

So I have printed out zoomed OSM map with visible building numbers on paper. I walked around the town and noted down if something was not correct (I have done this in 4 separated sessions). After each session I started JOSM and corrected houses that needed correction, removed 'import notes' from houses, added source:conscriptionnumber.

My findings

  • I had 4 walking sessions around the town, each took me about 1,5 hour and fixing the data in JOSM was another 30-45 minutes. That sums up to 8-9 hours for my small town!
  • 73/632 of houses did not have visible numbers on the house
  • 10/632 houses were not reachable to verify their number - they were inside locked yards, and number was not on the gate either
  • 26 houses look like a real house with families living for some time inside, but they have no number in cadastre or on the house
  • ~5% of houses in cadastre data were somehow wrong - incorrect number, two houses had the same number (either completely different houses or two joined buildings, sometimes one of them is garage)
  • it is not good to do paper-walk mapping in cold weather, your fingers freeze off :)
  • people stare at you if you are looking on buildings and note something into a paper sheet :-)

I have realised that after 4 walking sessions I am still missing some data and had to make 5th, and yesterday I was checking all the data if they all have a proper source:conscriptionnumber and I realised that I'm still missing that on 30 buildings and I need to make 6th walk.

What would I do differently next time

  • do walking sessions while it is summer and you can feel your fingers, otherwise you will need to wait for next warm season
  • print out walking papers in good detail and think if there will be enough space to write comments on walking papers
  • write real comments on walking papers, not just abbreviations, you forget those abbreviations if you upload the data after few days

Visualisierung der OSM-Aktivität der letzten 10 Jahre

Visualisierung der OSM-Aktivität der letzten 10 Jahre 1 | © Mapbox, © Lukas Martinelli, © OpenStreetMap Contributors

In eigener Sache

  • Bei der Meldung zu OSV ist uns letzte Woche ein Fehler unterlaufen. Danke Jochen.

Mapping

  • Seit 22. August wird über das vorgeschlagene Tag healthcare=midwife für eine Hebammenpraxis abgestimmt. Die Abstimmung läuft bis 5. September.
  • Wird MAPS.ME das name-Tag nicht mehr mit chinesischen Zeichen „vollmüllen“? Hoffentlich.
  • In einem Blogeintrag erklärt Seth Fitzsimmons die technischen Details von Portable OSM.
  • Joost Schouppe berichtet über offene Straßendaten in Flandern (Belgien) und wie sie für OpenStreetMap genutzt werden können.
  • Mapbox’ mappende Angestellte schauen sich in letzter Zeit öfter „verdächtige“ Änderungssätze an, seien es Änderungssätze von Neulingen oder Importe/mechanische Edits. Benutzer manoharuss fragt in seinem Benutzer-Blog, wie lange man bei Änderungssatz-Diskussionen auf Antworten warten solle. Sein Kollege nammala listet die von ihm gefundenen fragwürdigen Änderungssätze in seinem Benutzer-Blog auf.
  • Christian Quest hat ein Bash-Skript geschrieben, mit dem man Mapillary-Bilder vor dem Hochladen von einem iPhone kopieren und georeferenzieren kann, um sie direkt in JOSM nutzen zu können.

Community

  • Escada erklärt Jorieke Vyncke (Belgien) zum Mapper des Monats.
  • „OpenStreetMap am Scheideweg“ überschreibt Laura O’Grady ihre E-Mail, in der sie aufzeigt, wie die Kommunikation zwischen ihr als „local craft mapper“ mit einem „Roboter Mapper“ nach kurzer Zeit von diesem beendet wurde. Laura bezieht sich in ihrer E-Mail ausdrücklich auch auf den lesenswerten Artikel OpenStreetMap at the Crossroads von Jonathan Crowe, der die Aussagen von Migurski (wir berichteten) relativiert und widerlegt.
  • In Ausgabe 52 ihre Podcasts Mikrowelle sprechen ubahnverleih und thomersch über OSM-Apps für iOS (Kapitel „OSM für den User“ ab 00:30:55) und kommentieren den Mike Migurskis Schmäh-Blogpost (Kapitel „Craft Mapping“ ab 00:39:40), über den wir auch schon berichtet haben.

Importe

  • Die Ankündigung einer Mapping-Party in Minneapolis sollte eher nicht nachgeahmt werden: Sie will Neulingen zeigen, wie man ungeprüft massenhaft Daten aus öffentlichen Quellen in OpenStreetMap importiert. Damit wird allerdings ein falsches Bild vermittelt – sowohl von unserer Arbeit als auch bezüglich Sinn und Zweck von OSM.
  • Die OSM versus TIGER 2014 Battle Grid ist mit Stamen-Kacheln im Hintergrund auferstanden. Die Karte zeigt Bereiche auf, in denen die TIGER-Import Daten von OSM abwichen. Hier sind also Anpassungen notwendig, denn manchmal bedeutet es, dass die TIGER-Daten schlechter als OSM sind. Helfen wir doch unseren Freunden und lösen ein paar Quadrate auf http://184.73.220.107/battlegrid. 😉

OpenStreetMap Foundation

  • Da die OSMF sich von ihrer jetzigen Bank, der Barclays Bank, schikaniert fühlt, ist sie auf der Suche nach einer anderen Bank. Frederik Ramm bittet daher um Ratschläge.

Veranstaltungen

  • Ort und Zeit für die Abendveranstaltung auf der State of the Map in Brüssel stehen fest. Der Eintritt ist im Eintrittspreis zur Konferenz enthalten.
  • Am Freitag dem 26. August 2016 findet in Kolumbien von 08:00 bis 12:15 Uhr ein interessanter Mapathon statt. Ziel sind u. a. Straßen dritter Ordnung. Neu an diesem Mapathon ist die interessante Beschränkung u. a. bei Einzelteilnehmern auf spanisch sprechende Studenten und bei den Gruppen auf universitäre Gruppen aus Kolumbien. Ein ebenso interessanter Aspekt ist die Tatsache, dass in jeder Kategorie Prämien (von einer Mapping-Reise bis zu einem Tablet) ausgelobt wurden. Über solche Aktionen könnten Universitäten in Deutschland auch einmal nachdenken.

Humanitarian OSM

  • HOT hat mit weiteren Partnern im Pazifikraum Möglichkeiten erörtert, mit Drohnen schneller auf Katastrophen zu reagieren.

Karten

  • [1] Lukas Martinelli hat mit osm-activity eine Karte veröffentlicht, auf der man die Mapping-Aktivitäten der letzten 10 Jahre in OSM sehen kann. Die Quellen liegen auf Github. Lukas Martinelli zu seiner Karte: „Beim Klick auf eine Region wird eine Timeline angezeigt und es lassen sich einmalige Importe und langfristige Trends erkennen“.
  • Die OpenTopoMap kann derzeit nicht mehr aktualisiert werden, weil die SSDs auf dem Server ausgelastet sind. Um Platz zu schaffen, sucht Maintainer Stefan Erhardt Unterstützung dafür, den Speicherbedarf der Höhenlinien zu reduzieren.
  • Vom Unterseekabel über Funktürme bis zum Kabelverzweiger, all das findet sich im The New Cloud Atlas, einer Spezialkarte für Telekommunikationsinfrastruktur, die Tim Waters auf der Mailingliste Talk und in seinem Blog vorstellt.

The future needs better maps...

I enjoy following news about selfdriving cars. I have been watching the progress since the first DARPA GC. So I enjoyed reading this article especially the comments, about their need for better maps.

iD with modules 🔜

There's long been a desire & incoming wish for iD to be modular. Modular is a pretty general term, so I'll narrow it down into three general goals:

  1. Modules as a way of building a system. Using rollup, browserify, etc., in order to structure code and separate internal components in a nice, predictable way.
  2. Modules as a way of letting other systems include yours. Generally, in JavaScript-land, means publishing to npm.
  3. Modules as ways to include new code in your project. This is more in the vein of iD plugins. Supporting plugins would let us support contentious or rare needs without bikeshedding their inclusion to the main project.

With the help of Bryan, Kushan, David, Beau and Martin, we've made significant progress toward the first goal and are nearly at the finish line. iD will be switching from a system where we concatenate source files and use GNU make as a build process - to one that uses rollupjs to build a bundle from JavaScript modules. The expected benefits are big, for maintainers:

  • iD no longer relies on the global namespace for dependencies like d3, so there's less chance for conflict.
  • misnamed requires or invalid requires will be caught early
  • we can use npm modules for our dependencies, rather than keeping them in the project's source tree
  • we'll be able to build a faster and more reliable environment for development
  • we're upgrading d3 to v4, keeping it in line with the changing software world.

This doesn't immediately win us (2) and (3) but it pulls them closer. Soon, a new editor could reuse iD's data model, and iD could load new functionality from a plugin.

And there likely won't be any user-facing change as part of this port. This is the stage where the developers throw tens of hours into the low-level guts so that plugins can be possible and long-term maintenance can be less painful.


Bryan and I are working on the final steps of this modularization. I'll take some time to land: this is a major refactoring of a large project with a lot of functionality, so it involves a huge amount of work and has many opportunities to introduce regressions. We ask for your patience and/or support during this time.

Once we've ensured that the refactored iD is just as good, then it'll be the future, and we'll be excited to keep moving toward a more interchangeable stack of tools for OSM.

Singasandra, Bengaluru — a Mapping disaster

I recently moved to Singasandra and realised that being a new colony, this area was very badly mapped. The creation of AECS(Aeronautical Engineers Cooperative society) Layout involved the area being carved out of Chikka Begur village, Singasandra. Not the problem is that the area is not not mapped correctly on any official or non-official platform. Let me Illustrate

The highlighted area is designated as AECS B Block(Verified on location) Given that its a new area, there are very few location markers placed by authorities- precisely 3 in the area(highlighted below) (1) Marked as 2nd Main Road (2) Marked as 3rd Cross Road (3) Marked as 2nd Cross Road

(1) Marked as 2nd Main Road (2) Marked as 3rd Cross Road (3) Marked as 2nd Cross Road

These are the only 3 physical markers in the area and the rest of the area just has to guess its own address. All the roads have been marked out on the basis of these 3 reference points. But there are some major issues here.

Physical markers

Point 1–2nd Main Road is a north-south running road as per the convention. But, Where is the 1st Main Road? It cannot be the one as labelled because that is an east-west road and should ideally be a Cross Road Points 2 & 3–2nd and 3rd Cross roads are marked by physical markers. These are north-south roads and should not ideally be Cross Roads, they should be mail roads. This has led to a complete breakdown of the addressing system.

localities

Approximate locality boundaries The addresses in AECS B Block area identify themselves with Begur, Singasandra and Kudlu whereas they all belong in Singasandra. This may seem like a trivial issue but there are many real-world implications in this hyper-local world we live in. It is almost impossible to accurately call a cab because this area is not correctly mapped o google maps(the service that is used by Ola ad Uber) and hence cab drivers go in circles around the house without actually being led to the correct location. Same goes for grocery deliveries and courier deliveries. Sharing a location with a friend marking the location of the house is pointless since the navigation does not understand how to direct them here. Calling upon fellow mappers to help resolve this issue.

Map Assumptions

Among the things that have changed, since I was previously an active in 2010, is the way parking lots are defined. When there were none on the map, a parking lot area appeared to be a Public Parking Area, such as one that you might see on a road sign. The information seemed to be directing you toward a widely acceptable place for parking.

Today, every flat, paved place that one might find a few vehicles left turned off has a parking polygon. So, the meaning of the map has changed, but the data structure has had trouble keeping pace.

I have learned about how parking lots are used in today's OSM. I have attempted to add the "access" tag to the parking lots in my area, including the data that I entered many years ago. The vast majority of parking lots are privately maintained, but without the "access" tag defined, the (unofficial) default is public since they are accessed through public roads. Certainly many renderers put a (P) symbol which is commonly used for Public Parking Areas. That means more work for the mappers. I spent many hours adding "access=customers" to commercial locations or the key "access=private" to more remote locations.

The examination of social structures is one thing that gets me so excited about mapping. And nothing looks at the public-private social contracts more closely than the "access" tag. We can talk about whether the data or the renderer should be defaulting to public or private, but it comes down to this basic question: "Who is permitted to use that place?" Some of the information in OSM is the very complicated answer to that question. Little wonder it is hard to keep that data correlated with our assumptions.

Bing contra Wirklichkeit

Die Faszination des Bing-Luftbildes als Mapping-Quelle macht sich besonders dann bemerkbar, wenn man eine Gegend bearbeitet, die in der Vor-Bing-Ära gemappt wurde, meist nach einmaligem Abtracken per GPS, wo schnurgerade Straßen Schlangenlinien machen oder um 50 m versetzt sind. Man lächelt milde und stellt das alles „richtig“. Nach dem Bing-Luftbild, versteht sich, denn das hat ja recht.

Oder?

Auch 170 Jahre Fotografie und fast ebenso viele Jahre Fototricks haben uns offenbar noch nicht abgewöhnen können, das, was wir realitätsnah auf einem Bild sehen, als Wahrheit zu betrachten. Auch Bing verführt uns in dieser Weise. Dabei wäre Vorsicht angebracht. Schaun wir mal auf die B 54 nördlich Bad Schwalbach: Fehlerhafte Straßendarstellung

Wieso ist die Straße ein gerader Strich? Hat es sich hier nicht ein Mapper zu einfach gemacht? Auf dem Luftbild geht sie doch nach rechts. Komm, das müssen wir gleich mal korrigieren!

Ich kenne diesen Reflex. Aber in diesem Fall widerstehe ich ihm, denn ich kenne auch die Straße persönlich. Und die verläuft da genau so, wie sie gemappt ist – der Bogen nach Osten ist schlicht ein Fehler im Luftbild. Man könnte es anhand der relativ scharfen Knicke an den Enden schon ahnen, kein vernünftiger Mensch baut so was in eine Bundesstraße ein.

Tröstlicherweise ist auch die Vereinigung Hessischer GPX-Tracks mit überwältigender Mehrheit dieser Meinung: Gerade GPX-Tracks

Wie kommt es zu diesen Fehlern? Nun bin ich kein Fachmann im Geoingenieurwesen, aber ich reime es mir etwa so zusammen:

Nicht jeder Punkt des Luftbildes ist senkrecht von oben aufgenommen. Das geht ja gar nicht. Das Luftbild besteht aus vielen Einzelaufnahmen, und alle Punkte, die zufällig am Rand des Bildfeldes einer Einzelaufnahme lagen, wurden schräg fotografiert.

Aber das macht ja nichts – wenn da nicht das Gelände wäre.

Nimm zur Verdeutlichung mal an, rechts außen im Bild steht ein Aussichtsturm auf einem Berg. Dessen Turmspitze sollte einklich mittig über seiner Standfläche sein, von der Geoposition her, alles andere wäre für den Turm gar nicht gut. Ist sie aber nicht, weil der Turm schräg fotografiert wurde, er scheint auf dem Bild zu kippen, die Spitze ist weiter außen als die Grundfläche. Welcher Punkt des Turmes ist jetzt seine „richtige“ Position, wo setzt du den Node hin? Und jetzt kommt’s: Das gilt nicht nur für den Turm, sondern auch für den Berg, auf dem er steht. Auch der wurde schräg fotografiert und kippt deshalb nach außen (das fällt nur nicht so auf wie beim Turm).

Deshalb müssen Luftbilder aufwendig entzerrt werden: Man legt ein Höhenmodell des Geländes darüber, berechnet für ein Raster von Referenzpunkten den seitlichen Versatz, der sich aus Höhe und Aufnahmewinkel ergibt, und verbiegt das Bild entsprechend in die andere Richtung. Hoffentlich halbwegs zutreffend. Denn erstens kann dieses Referenzpunktraster nicht beliebig engmaschig werden, deshalb stimmt die Entzerrung immer nur im Mittel, und zweitens ist auch das Höhenmodell nicht metergenau und löst keine feinen Strukturen auf.

Wenn das klappt, steht das untere Ende unseres Turmes auf der richtigen Geoposition. Aber in einem engen Flusstal wie dem Aartal oben im Bild kann es da schnell passieren, dass entweder das Höhenmodell nicht genau genug ist oder die Referenzpunkte zufällig auf den Hängen statt im Talgrund liegen. Die Punkte dazwischen werden ausgemittelt, und schon haben wir den Salat – eine gerade Struktur wird ans Gelände angepasst. Weil die Software zufällig auf die Hänge korrigierte, nicht aufs Tal.

TL;DR: Auch Bing verkündet kein Evangelium. Die Luftbilder müssen entzerrt werden, um einigermaßen lagegenau zu sein, und diese Entzerrung hat ihre technischen Grenzen. Die genaueste Quelle ist immer noch Ortskenntnis und eine Vielzahl von GPS-Tracks, deren Messfehler sich ausmittelt.

STL;SDR: Bing ist keine Quelle, Bing ist ein Werkzeug.

Reviewing Turn restrictions in Germany using Mapillary

This diary post last week outlined an overarching goal of making OpenStreetMap navigable, and our intent to investigate and add missing turn-restrictions in Berlin, Stuttgart, and Wolfsburg using Mapillary as a source. We received some good questions from the local OpenStreetMap community about using Mapillary as a source. Considering the concerns of the community, we did a preliminary research on the Mapillary imagery to ascertain their recency. We want to share our findings here.
Here is an animation showing Mapillary traces in Berlin, Stuttgart, and Wolfsburg spanning the last six months (March - August 2016). Not surprisingly, Berlin was found to have the best Mapillary coverage. The coverage in Stuttgart and Wolfsburg was sparse in comparison.

Berlin2 Berlin Mapillary Coverage

Stuttgart2 Stuttgart Mapillary Coverage

Wolfsburg Wolfsburg Mapillary Coverage

Recency of Imagery

When adding data on OpenStreetMap using any type of source, recency is an important aspect to consider. The plan is to add data on OpenStreetMap only if Mapillary imagery is more recent than when the turn-restriction was added. If this is not the case, or there was a recent change in the area, the intent is to add a note, and rely on the knowledge of the local community to verify accuracy. Based on this approach, here are a few cases where turn-restrictions could be added. To the best of our knowledge, these are valid turn-restrictions that are not added on OpenStreetMap. To do this, we're using the OSM Navigation Map to detect turn-restrictions, and their absolute positions using Mapillary. We'd appreciate if anyone with knowledge of these areas can verify if these detected signs are in fact correct or not.

screen shot 2016-08-23 at 11 48 50 am

We had carried out our preliminary research in reviewing Mapillary detected turn restrictions in these 3 cities, using OSM navigation map. We time boxed this task to 2 hours with two people working on Berlin and one each working on Stuttgart & Wolfsburg. We were able to find 25 missing turn restrictions out of the 110 we reviewed. Turn restrictions are categorised as valid/invalid/redundant based on the Mapillary detected signboards and by the OSM data present.

Case 1:

Case 2:

screen shot 2016-08-23 at 12 08 56 pm Missing No U Turn (Link to OSM note)

Case 3:

Case4:

Missing only_straight_on (Link to OSM note)

Case5:

screen shot 2016-08-23 at 12 54 41 pm Missing only_right_on (Link to OSM map)

Also, some other missing cases are listed here.

While we reviewed turn restrictions that can be mapped using Mapillary, we also verified some of the existing turn restrictions and encountered few cases where community feedback would help

Case 1:

  • In the case below, the image shows that there are restriction signages for each lane
  • Also the turn restriction added was a no_u_turn, which did not show up in the Mapillary.
  • In such a case, what is the approach community would suggest?

screen shot 2016-08-23 at 4 07 49 pm Link to the map.

Case 2

  • In this case the signboard is showing only_staright_on but it was added as two separate turn restrictions, no_left_run & no_right_turn.
  • As per the German wiki it should have been added as only_straight_on.
  • We would like to get feedback on adding such turn restrictions, what is the general convention the community follows?

screen shot 2016-08-23 at 5 38 25 pm Link to the map

Case 3

  • We have observed a no_straight_on restriction which seemed odd as it was on a dual carriage way with highway=teritiary tag.
  • We could not verify this with Mapillary images, as there was none on the road. It would be great this can be verified by the local mappers.

screen shot 2016-08-23 at 5 52 39 pm Link to the map

Based on the community feedback received, we are ready to add OSM notes for the missing turn restrictions if the community has no issue with this and also open to getting any thoughts you have on improving the OSM Navigation Map whether it's feature requests, or bug fixes here.

Thank you :)

Grüße,

Experimenting with ClearTables, self-hosted vector tiles, and Tangram client-side rendering

I've been experimenting with generating my own vector tiles and client-side rendering with Tangram in order to figure out how to best write a style in its language.

Tangram is a GL-based renderer written by Mapzen and normally used with their Tilezen vector tiles, but I'm interested in being able to make my own vector tiles with different cartographic choices.

Having a diverse selection of vector tile schemas is important, as is avoiding a situation where only large players in the market can get involved like right now.

For a toolchain I used osm2pgsql with ClearTables and Mapnik via Kosmtik to write vector tiles. With the demo I'm serving pre-rendered vector tiles from disk, but Kosmtik is useful in development with it's xray functionality. I input the style into Tangram Play, a web-based editor that automatically reloads the map when you change the style.

The cartography and vector tile definitions are loosely based on OSM Clear, a demo style I wrote. I didn't want to learn the language while designing new cartography at the same time. Being a learning exercise I don't consider the style complete or free of bugs.

The demo page is on my server at http://tangram-clear-demo.faramir.paulnorman.ca/ with the style and vector tile code at https://github.com/ClearTables/tangram-clear-demo.

I'm not sure what direction I'm going to take next as I don't have any particular style goals right now, or collaborators.

Data results for Parished/Unparished Areas

A recent Diary entry (A Suggestion to Fix Poor LSN in the UK) contained the phrase “Why those facilities fail for a substantial part (40%) of the UK”, and I promised to publish the raw data that led to the ‘40%’ claim. This is the fulfilment of that promise and be warned, it is long & intensely computer geeky.

In brief, that earlier Diary entry said:

  1. Location, Search & Naming facilities (LSN) require the presence of an “admin_level=10” (civil parish) area in the UK
  2. 40% of the UK does not have such an area, as it is unparished
  3. (thoughts on how to fix it)

The above both is, and is not, true (real life is usually a bit more complicated than that) but it was the best that I could manage & wanted to get the debate kicked off. In addition, some later spreadsheet-work (see bottom) indicates that it is more like 60% for the nations' cities, and 100% for all the major conurbations. Now for the methodology of acquiring, plus full results that led to, the 40% claim...

A site maintained by The Maarssen Mapper contains a page of all UK Civil Parishes in the form of GPX file downloads. The top of each file has an XML header that looks like this (this one is Birchgrove_Community):—

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

            <TYPE_COD0 />
            <DESCRIPT1 />
        </extensions>

<HECTARES> is the important item in this header (the acreage of the area), although <FILE_NAME> is also used in the code below, as that helps group all the parishes by District, etc (“admin_level=8”).

Although this is a page of Civil Parishes, being Britain, there are also a large number of Unnamed Shapes. These are the Black Holes of the Boundary world, the Unparished Areas. Those files' Headers are similar in almost all respects to the ordinary CPs. Importantly for ourselves, they contain both <HECTARES> & <FILE_NAME>.

I created a directory called ‘cps’ which contained all CP files, and another called ‘cps_un’. All Unnamed Shapes were extracted from ‘/cps’ and placed into ‘/cps_un’. The awk command (below) is using a space as a word-splitter, so it is important that <FILE_NAME> does NOT contain any spaces. Naturally, some files did in both dirs. The following command was used to discover them, then the header edited:

egrep -li "<FILE_NAME>.*[ ]+" JOSM/parishes/cps_un/*

The final item is that xml_grep is installed under Debian/Ubuntu as part of the xml-twig-tools package.

The following command-line script was built (testing all the way) to show unit & combined acreage for both sets of files:—

xml_grep
     --text_only
     --root HECTARES
     --root FILE_NAME
     --wrap JOSM/parishes/cps/* |    
paste -d " "  - - |    
awk '
    { sum[$1] += $2; TOT += $2; NUM += 1 }
    END
    {
        AVG=TOT/NUM;
        for (k in sum) { printf("%s: %d\n", k, sum[k]) }
        printf("ZZ %d Parishes; Total area=%d hectares; Average/Parish=%d \n", NUM, TOT, AVG)
    }
' |    
sort

(I've broken it down into sections, but it was used as a single line)
(being able to easily construct the above is one of the values of Linux)

The identical command was used on both directories, changing only the dir reference in the command. Here are the results:

Experience with Mapping

I decided to spend some time mapping on OpenStreetMap after starting at Mapbox to help build better mapping tools later. After having show and tells with Mapbox buddies, I started off with mapping my hometown. Though I had not very perfect memory of the places in my hometown as I am away from it from many years, but there were few places which I was sure about. As it is advised to add data with 100% accuracy only, therefore I tagged only the sure places in OSM. When I downloaded the data for my city Gandhidham in JOSM, to my surprise, the city was well traced by a remote mapper. Therefore I worked on adding known POIs. It was fun to look for my home from the satellite imagery and tag its address.

Next I traced roads in city called Raipur. It was like taking part in an enjoyable drawing task while keeping a few rules in mind. Adding intersections, junctions, classification of roads has a huge impact on the routing. So I did that quite carefully.

Later I moved on to tracing buildings in Baga Beach, Goa. While working on this task I found many buildings that were quite interesting. Also, there were many row houses present in that area. Therefore to do it efficiently, I tried exploring the shortcuts of JOSM i.e. Making a big building and splitting it into pieces.

The most fun and interesting part of mapping was Field Mapping. To execute this we went in a group and split into sub-groups for covering a bigger region to map. I teamed up with Srividya. We planned to collect details like building addresses, levels, amenities , trees, streetlights in the neighborhood area of Mapbox office.We used OSM Tracker, mobile application for field mapping. For mapping all the buildings and amenities, we assigned each building a text note with all its details and took few photographs of the same which later helped us to upload the information in JOSM. For mapping trees and streetlamps , the presets came in handy, as you just have to tap on the mobile screen, whenever you encounter any tree or streetlamp. But the problem being we could not find any preset for tree and streetlamp. Therefore Srividya and me found out this trick to encode things up. We used 'Shelter' preset for tree and 'Surveillance' preset for streetlamp. Field mapping helped to explore and understand the neighborhood better.

Overall, mapping the places was a wonderful experience. Looking forward to keep making more edits in OSM.

Opensnowmap Tile Usage Policy

Opensnowmap offers overlay tile layers for ski pistes and winter sports. Two sets of tiles are available: one with only the pistes, and another one with relief background (shaded relief and contours lines).

It seems that the layer with relief information is of great interest, even in summer.

Sadly, opensnowmap server won't be able to cope well with the demand on next winter, so in order to keep the server healthy for skiers, the tile usage condition from outside Opensnowmap will change as follow :

  • From the 1st of october 2016, a valid referer will be mandatory to fetch tiles from www.opensnowmap.org.
  • From the 1st of november 2016, access to tiles with relief from outside opensnowmap.org is not granted anymore and can stop at any time (likely around the 1st).

Learning Mapping

What is Mapping?

It is an operation which associates elements of one set with the one/more elements of another set. When we talk about mapping in OpenStreetMap, the similar concept is followed. In that, we associate the real life objects (Home, Parks, Schools, Roads, Water bodies) to 2D elements like node, ways and polygons. This means that we can traverse any place virtually by looking at the map and can a get a sense of directions, locality, etc.

What are the objects which can be mapped?

It can be mapping different amenities, POIs, roads, buildings, water bodies, turn restrictions, different transport networks, Trees, Street lamps, so on. This list is never ending as each of them has a special purpose of being added in the map. The more detailed it is, the more it helps in understanding the place geographically. Details

How do we Map?

Basically there are two steps involved to map a place:

  • Tracing - With the help of satellite imagery and tools like In-browser editor/JOSM, one is able to trace various buildings, roads, water bodies remotely. For learning JOSM, one can follow this blog. Tracing

  • Tagging - Once we are done with tracing, we can start adding particular details like name, type, etc depending what kind of entity ( node / way / polygon) it is. If one is well familiar with the details of the place, then it can be done remotely. The best example for it will be mapping your hometown. For the mapping the unfamiliar places, Field mapping comes in picture. It is a technique in which a person goes to the actual area and maps it. There are mobile applications like OSMTracker, Vespucci which are helpful for field Mapping. One can also use the field papers. To learn more about field mapping, one can follow this blog. Labelling

MAPS.ME

Maps.Me Navigasyon Uygulaması

Sade ve Kullanışlı

Android ve İos işletim sistemlerinde bulunan ve Openstreetmap haritasının verilerini kullanan en güzel ve sade navigasyon uygulamalarından biridir. Haritanın akışkanlığı, tasarımı ve sadece temel navigasyon ayarları ile geniş bir kullanıcı kitlesine hitap ediyor.

Çevrimdışı ve Ücretsiz

Uygulamayı herhangi bir ücret ödemeden istediğiniz ülkenin haritasını cihazınıza yükleyerek internetsiz bir şekilde özgürce kullanabilirsiniz.

Harita Düzenleme

Openstreetmap kullanıcıları için en önemli özelliği budur. Bildiğiniz gibi openstreetmap'e katkıda bulunmak için her zaman bilgisayar başında bulunamıyoruz. İşte bu noktada dışarıdayken gördüğümüz haritaya eklenmemiş eczane, market, kafe vb. bir çok noktayı anında uygulama üzerinde "Haritaya Bir Ekleyin" seçeneğiyle ayrıntılı tanımlamalarla birlikte ekleyebiliyorsunuz. Ayrıca daha önce haritaya eklenmiş binaların kapı numarası, sokağı gibi ayrıntılar eklene biliniyor.

Sesli Yönlendirme

Oluşturduğunuz rotada Türkçe sesli yönlendirme seçeneği de bulunuyor.

Güncelleme Aralıkları

Bir çok uygulama harita verilerini aylarca güncellemiyor. Ancak Maps.Me uygulaması genelde 1 ay olmadan openstreetmap'teki verileri çekerek haritalarını güncel tutuyorlar.

Popülerdir

Android'te 10 milyon fazla indirme rakamına ulaşmış.

Progress of Navigation Mapping in Canada!

With an aim of making OpenStreetMap more navigable and accurate in routing, we started mapping turn restrictions and exit-destinations in Canada in its five important cities: Toronto, Ottawa, Montreal, Vancouver and Calgary. The tasks which spread over a month have been completed; we have finished adding and validating both turn restrictions and exit-destinations in the selected cities of Canada with the support from the OpenStreetMap community.

Summary of improvements

Mapping turn restrictions was flagged off on 21 of July with data team and the community working on adding missing turn restrictions and validating the ones that are present.

As the mapping progressed, workflow was getting updated every time the team had some doubts regarding how best to map a particularly different turn restriction that was detected. The questions we had were posted on the mapping ticket we used and the community got back to us almost immediately with clarifications to our questions. We completed both adding and validating turn restrictions in 14 days.

Exit-destination mapping started on August 11. For exit and destinations, a slightly different approach was followed, unlike how we mapped previously using only checkautopista2. Each highway was considered a separate task, which was integrated into tasking manager, with a specific link to checkautopista2 that loaded that particular highway that was selected using tasking manager.

Below is the full breakdown of how many turn restrictions and exit-destinations were mapped:

image

Status of existing data and Mapillary coverage

We could map extensively in Toronto because of great Mapillary coverage. Ottawa had us verifying the existing exit-destination tags rather than adding new ones because most of them were already mapped. 🎉 The community raced us in adding exit-destination tags in Vancouver! 🚀 Due to less Mapillary coverage, we couldn't map much in Montréal and Calgary. We wrapped up adding and validating exit-destinations in 9 days :)

Community support

Both the projects were met with an amazing response from the community. It was great to have you all working alongside us, helping us in adding missing data, calling out and correcting our errors, keep tabs on our edits, and clarifying doubts and questions, letting us make edits to previously added data. We thank everyone, especially Andrewpmk, Rps333, James2432, Bootprint, Puec, Fmarier, Scruss, for your support and guidance and hope the collaboration and involvement continues in all our future projects. We will continue navigation mapping in Canada, specifically in Montreal and Calgary once there is enough Mapillary or OpenStreetView coverage for us to add data and verify them.

Until then,

Cheers!

Mapbox Data Team :)

Spotting Cemeteries in Texas

I am collaborating with agencies in Texas to update both OSM and Texas data. The pilot project deals with cemeteries. I received a file with almost 7000 cemetery locations. (Even if the idea that there are more people living today than have died thus far in human history turns out to be a myth, I think that is quite a lot!).

The first phase of this collaboration is to see which cemeteries in the Texas data actually exist. We will use MapRoulette for that. Simply go to the Cemetery challenge at maproulette.org and start looking at tasks.

If you see a cemetery in the aerial image, click 'skip' to go to the next one. If you don't see a cemetery, click 'False Positive'. If you are in doubt, click 'skip'.

How can you tell if there is a cemetery? Sometimes it is hard. Look for fine patterns defining the plots, and usually there will be a service road connecting the cemetery to the road network. Sometimes, in larger cemeteries, you may also see paths inside the cemetery. Finally, the marker may not be right on the cemetery, so look around a bit as well. Below are some examples of cemeteries and non-cemeteries.

Once we complete stage 1, we will turn to mapping all the cemeteries that are not yet in OSM yet!

There is a cemetery here: fine regular pattern indicating plots, some paths.

Status der OpenTopoMap

Die OpenTopoMap feiert am 03.09. seinen fünften Geburtstag! Als Versuch gegründet von zwei Studenten unterschiedlicher Fakultäten entwickelte sich die OTM zu einem Kartenprojekt, das mittlerweile nicht nur innerhalb der OSM-Community ein Begriff ist. Das heutige Kartenbild hat sich im Vergleich zum allerersten Testbild glücklicherweise weiterentwickelt: OTM 2012 Zum Vergleich: OpenTopoMap heute

Auch die Besucherzahlen und damit die Anforderungen an die Hardware stiegen kontinuierlich. Derzeit rufen gut 30.000 Besucher mehr als 90 Mio. Kacheln pro Monat ab. Die Garmin-Downloads, die glücklicherweise auf einem anderen Server liegen, kommen auf 17 TB/Monat. Besucher Zugriffe

Möglich ist der Betrieb überhaupt nur durch die Unterstützung der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) und dem Regionalen Rechenzentrum Erlangen (RRZE). 2012 finanzierte die Universität dem Projekt einen Server, der dankenswerterweise am RRZE untergebracht und versorgt wird. 2015 finanzierte das Department Geographie eine SSD mit 1,1 TB, die über PCIe angebunden ist. Und erst vor Kurzem wurden von der Universität dankenswerterweise Mittel für weitere HDDs im RAID mit 3,6 TB nutzbarem Speicherplatz bewilligt, um auch die größeren Zoomstufen vorhalten zu können.

Seit Anfang 2016 konnte dank der 1,1TB-SSD der Versuch gewagt werden, den gesamten Planeten abzudecken. Selbst die minütlichen Updates brachten den Server bezogen auf die Rechenzeit nicht mal ansatzweise an seine Grenzen. Die OSM-Datenbank (osm2pgsql ohne HSTORE) wuchs allerdings so stark, dass der automatische Import vor wenigen Wochen gestoppt werden musste. Neben den OSM-Daten (495 GB) liegen nämlich auch 505 GB an Höhenlinien als Datenbank auf der SSD.

Die Konsequenz ist klar: Die Höhenlinien-Datenbank muss um mindestens 100 GB reduziert werden, um der OSM-Datenbank Platz für die nächsten Monate und Jahre zu verschaffen. Auch kartographisch wäre dies sinnvoll: Der weltweite Höhenlinienabstand von 10 Metern ist spätestens in Hochgebirgen alles andere als übersichtlich (Beispiel). Man kann also getrost auf so manche Höhenlinie verzichten. Das Problem ist nur, einen Algorithmus und dessen Parameter zu finden, mit dem automatisiert alle Höhenlinien weltweit ausgedünnt werden können. Übrigens enden Höhenlinien auf professionellen Karten durchaus auch mal im Nichts, wenn zwischen Detailgraden gewechselt wird. Vermutlich muss man nach (evtl. zusammenhängenden) Gebieten suchen, in denen Höhenlinien gelöscht werden.

Derzeit bin ich der einzige technische Entwickler der OpenTopoMap. Glücklicherweise habe ich neben der OTM noch andere schöne Hobbys, wodurch die Entwicklungszyklen allerdings extrem lang werden. Gerne würden wir weitere Entwickler aufnehmen und nach der Höhenlinienproblematik auch weitere Ideen ausprobieren. Sehr willkommen (und sich in einer E-Mail-Flut äußernd) sind natürlich weiterhin Anregungen und Verbesserungsvorschläge. Ohne ein Entwicklerteam, das größer als eine Person ist, stehen die Chancen auf eine schnelle Umsetzung allerdings schlecht.

Lange Rede, kurzer Sinn: Wir suchen nach Entwicklern! Wer sich berufen fühlt, möge sich gerne bei mir per PM oder Mail (stefan@opentopomap.org) melden.

Die Autoren des Projektes möchten nochmals ganz herzlich der FAU und dem RRZE für die Finanzierung und Unterstützung der OpenTopoMap danken.

Speed limits split ways

More speed limit changes in town centres. They need to be captured but I don't like breaking up the roads into little pieces. Subsequent searches just return a little bit of the original road.

# Wrapping up Google Summer of Code

3 months have passed and GSoC is about to an end. This small diary post showcases my contributions uptill now and it also lays down my next actions.

Major Contributions

Lane editor

The lane editor is my primary objective of the GSoC for this summer. These diary posts (1, 2) can be referred to get updated with the work.

Currently, most of the functional code is ready with 81 test cases testing most if not all edge cases possible. This code parses the osm data and gives a nice JSON output, which should then be supplied to the rendering.

Making iD modular

The iD contributors felt the need to start using the new ES6 module system back in April. I helped in the phase 1 and phase 2 of this process.

OSM hackday

I was a part of organizing team of this small hackday at Mapbox Bengaluru. More info

My pull requests

My commits

Next Steps

Well GSoC 2016 is approaching an end, but not my contributions. There are lot of things pending in my bucket list. The first thing I would like to finish in the coming months would be the lane editor's UI and deploy it for the use of OSM community.

I am really proud to be one of the core contributors of iD and would really like to thank the community, my mentor Bryan Housel and Google for the awesome GSoC program.
