Please introduce yourself

I am Julien Minet. I come from the Luxembourg province in Belgium, from the border between the Ardens and the Gaume. I have a degree as Bio-engineer and worked for 8 years as a researcher at UCL and now ULg - Arlon. At the moment I work in web development, GIS and digital maps.

Maps of Arlon

When and how did you discover OpenStreetMap ?

I heard about OSM quite some time ago, via news sites on mapping and GIS. I started contributing in 2012. I have to admit that I did not believe in the project in the beginning. Due to the empty, white map I was really attracted to contribute. Nevertheless, there were some brave pioneers that started the work and mapped the main roads, the villages, etc. J’ai entendu parler d’OSM assez tôt, par le biais de sites d’infos sur la cartographie et le SIG. Je me suis mis à contribuer en 2012. Au début, je dois dire que je ne croyais pas trop au projet et le fait que la carte était toute blanche dans le sud de la Belgique ne me poussait pas à y contribuer. Puis, de courageux pionniers ont initié le travail en cartographiant les routes principales, les villages, etc.

How do you map ? Is this different from your early days ?

I started in 2012, at the moment, several small villages were missing from the map in my neighborhood, which I added since then, as well as some main roads. In the beginning I mapped forestry roads after registering them via GPS traces. Afterwards, I started focussing on points-of-interests, mainly shops, pubs, restaurants, banks, etc. Later on, I moved to mapping the signposted walks in my area. Since a few months, I became addicted to map the landuse. The longer one participates in the project, the more subjects one finds to map! I believe it is always a good moment to get engaged in OpenStreetMap, since there is a always a lot of details remaining to be mapped, especially in rural areas.

In the last year, I started to use the error detection tool Osmose as lot. It is a very good way to learn about the rules, to discover other mappers in "your" area and to discover new features that can be mapped.

Initially I thought that OpenStreetMap was mainly constructed via imports of open data. Later on, I discovered that this was not the case (at least not in Belgium). Since then, I believe in the "craft mapping", mapping of items that one knows or has seen in the real world. Wanting to import open data at all costs, is no longer interesting for me, since 1) in case the data is open, it is available anyhow, 2) official data is not perfect and 3) OpenStreetMap demands some time to be constructed, so let some work to future contributors !

On the other hand, open data can be used in for analysing and validation of our map data, or in some specific cases. For examples, one day I would like to import the traces of the small waterways in Wallonia, because they are often missing in OpenstreetMap and they are difficult to map from aerial images. Since this would require a group of passionate people to follow the course of the rivers and streams, this seems like an import that is almost useful. Although swimming and walking along the streams is a great activity !

How do you map ?

Usually, I map what I know well, and after verifying it on the ground. I do not have a dedicated GPS-device for hiking, I only use my smartphone with the OpenGPSTracker app. I use it for all my outdoor activities, be it on a mountain bike or for walking. The latter happens less and less the past few years. Often, I take pictures of shops, especially of the notes indicating the opening hours and contact information, so I can later on add this information to the map.

Most of my edits where done with ID. I like this editor for its simplicity. I always use it for adding information such as opening hours, contact information, or to repair mistakes indicated by Osmose. Recently, I also started using JOSM for mapping landuse and lancover, using the "contourmerge" plugin, which is a great time saver for this type of mapping. I also use Maps.Me and Vespucci on mobile devices.

Where do you map ?

I mainly map what I know well, thus I work in my immediate surroundings and in the places I visit. I am interested in the helping out humanitarian projects such as HOT, but I hesite to start, because I do not know those places. In the beginning, I found some serieus problems in my neighborhood, clearly made by contributors that do not know the area. There has to be people in each region of the world that have an interest in becoming a contributor. Of course, the number of possible contributors interested in the project is alwayls limited, so we have to start with students following geography or IT courses. But we do not have to reach millions of people to get good results. It could be a surprise to see who is interested in the project and contributes to it. I had the possibility to meet some African students of the ULg in Arlon and I tried to introduce them to OpenStreetMap. They are often exited about the project, since it is valuable in areas where no other digital maps exist. So, yes to humanitarian mapping if one does not forget to involve local mappers, all over the world.

What is your largest achievement so far ?

I am proud of "my area", roughly described as the Forest of Anlier and Rulles, where I made most of my contributions. I am especially happy with the result, as the official IGN maps of the forests are not always up-to-date. Some paths can disappear rapidly under the vegetation and new ones are created by the exploitation of the forest and by mountain bikers.

Why do you map ?

I always loved maps, hiking and outdoor activities. That is what attracts me the most in OpenStreetMap: going out on a bike or by foot and later on edit the map to reflect what you have noticed. I also like the geek aspect, the fact that you have an unbelievable passion to share when you are invited for a dinner on a Wednesday evening.

What is the most difficult part ?

To keep the map up to date ! And to find the motivation to update or improve what is already present.

What are you plans in the near future ?

I talked about that on my blog, mainly the landuse and the sign posted hikes. And why not, mapping the small streams ?

Do you have contact with other mappers ?

I am subscribed to the talk-be mailing list. One warning: this list generates a lot of emails, so set up your mail program to keep them in a separate, dedicated folder. I only visited a few face-to-face meetings, as they are rarely organised in Wallonia. By accident, I met Julien Fastré during one of them and we have met a few times since then. I initiated some people around me to contribute, but they only do this from time to time. And at the State of the Map in Brussels in 2016, I finally met some of the legends of the Belgian community! I think this was the best day of my live ! :-)

Do you use OpenStreetMap yourself ?

I use OpenStreetMap on my smartphone, via the OsmAnd and Maps.me apps. Having the map available offline, is always useful. I also use it to calculate routes. And finally I use it in my activaty as GIS consultant: either as background map or as data source.

Are there other things you do that are related to OpenStreetMap?

I made OpenStreetMap part of my jobs. A project that I would like to develop further is a map of businesses and services in rural areas. A map, where one can rapidly find the opening hours and phone numbers. I have developed a prototype for my village, and I use it often to see whether a shop is open. I would like to present it to other villages and collaborate with local development agencies and trade associations.

To conclude, is there anything else you would like to mention?

For me, OpenStreetMap has an enormous potential, one that is not completely known yet. And even though OSM data is not always complete nor accurate, -- which largely depends on the theme and area -- it should not hinder the invention of new applications. There are a lot of professions that use geographical information, often only sporadically, but thet can still have benefit from using OpenStreetMap. The data model of OpenStreetMap and its open tagging system, are both part of the success of the project and contribute to its use in innovative solutions. But there are also disadvantages. One of the challenges is the completeness and the exactness of the data. Maybe, by creating derivations, or mirrors based on the original OSM data, that we can create more easily professional applications or services that are more reassuring to its users.

There are still a lot of features that have to be added or corrected in OpenStreetMap. I hope to encourage new people to get interested in the project and to get them contributing. It does not matter whether one is an amateur or a professional, everybody can contribute.

Хакатон MAPS.ME

В середине июня команда MAPS.ME почти в полном составе ездила на хакатон. Не чей-то чужой, вроде хакатонов по открытым данным или по дата-журналистике, а внутренний. Как два и три года назад, мы на несколько дней покинули офис и семьи, чтобы сконцентрироваться на экспериментах в развитии приложения. День подготовки, три дня работы и выступление в конце.

В середине июня команда MAPS.ME почти в полном составе ездила на хакатон. Не чей-то чужой, вроде хакатонов по открытым данным или по дата-журналистике, а внутренний. Как два и три года назад, мы на несколько дней покинули офис и семьи, чтобы сконцентрироваться на экспериментах в развитии приложения. День подготовки, три дня работы и выступление в конце.

Самая большая команда разработчиков, включая программистов под iOS и Android, набросилась на задачу UGC: добавить отзывы в карточки объектов. Кажется тривиальной задачей: мы видели отзывы и в специализированных приложениях, типа Foursquare, и в популярных онлайн-картах. Но приложение MAPS.ME хорошо не только дизайном, но и работой в отсутствие интернета. Как вы сделаете отзывы, когда нет сети?

В конце хакатона группа UGC показала звёздочки и смайлики для оценки заведений, но картинки не отразили масштаба работы. Разумеется, должны быть отзывы, и их нужно не только собирать в офлайне, но и показывать, то есть, хранить в файлах карт. Это требует лучших алгоритмов сжатия. Для ресторанов полезно спросить, понравилась ли еда, и какая именно, а для автомойки — качественно ли протёрли кузов и вежливо ли обошлись. Команда вручную просмотрела около 250 категорий объектов, выбрав для каждой признаки, которые могут быть интересны пользователям.

Поскольку внутренние идентификаторы объектов меняются с каждой сборкой карт, мы привяжем отзывы к идентификаторам OpenStreetMap. То есть, по сути, мы проектируем систему отзывов на объекты OSM — как давно мечтали некоторые наши участники. Прошлые попытки не вышли из статуса демонстраций для своих, а тут сразу будет аудитория из десятков миллионов пользователей. Наконец-то они будут писать «неплохая пицца» не в название ресторана, а в отзывы. Может быть, удастся договориться с руководством MAPS.ME об общей базе с другими приложениями на OSM.

Соседний домик в гольф-отеле, больше похожем на коттеджный посёлок, заняла команда метро. К сожалению, лопат не выдали и команда не создала ни метра новых линий. Но нарисовать в приложении MAPS.ME то, что уже выкопано, — почему бы и нет. Нас часто спрашивали, когда появится навигация с использованием общественного транспорта. Начать решили с простого, как казалось: схемы линий метрополитена.

OpenStreetMap — глобальный проект с единой системой тегирования. Если получилось нарисовать московское метро — получится и нью-йоркское. Так мы думали. Хорошая попытка, но нет: русские рисуют линии не так, как немцы, англичане — не так, как корейцы. Как вы знаете, схема метро состоит из трёх элементов:

  • Станции — на самом деле, это комплекс из платформы, точек, где останавливаются поезда, и станции как сущности. Нередко это четыре разных объекта, а то и больше. Схема общественного транспорта 2.0, при этом, забывает про точки railway=station в случае метро: это же не платформа и не остановка, дублировать нельзя. Это вообще не физические объекты! Мапперы иногда тоже о них забывают. А с отношением stop_area вообще получается тушите свет.
  • Линии — опять две сущности в одной. Это и пути, по которым движется поезд. Картографы очень любят их рисовать, потому что получается красиво, и считают их главной частью отношения маршрута. Увы, пользы от них ноль: важна линия как последовательность остановок, от первой до последней. И тут бардак. Причём, в России ещё нормально, пришлось править только московский МЦК, а в Лондоне многие линии почти не имеют станций.
  • Пересадки — их в OSM нет. Не в смысле, не нарисовали, а вообще: для пересадок нет схемы тегирования, никто даже не пытается их картировать. Иногда встречаются попытки смоделировать пересадки отношением stop_area, но лучше бы не пытались. Приходится определять пересадки по близости и затем удалять лишние рёбра.

В общем, за три дня и не такие данные удавалось выпрямить: мы не только автоматически обработали, пусть и с ручной доводкой, системы метро Минска, Москвы, Петербурга, Вены, Барселоны и Сеула, но и сделали полноценный интерфейс! Команда удивлённо наблюдала знакомые схемы в городской геометрии на затенённом фоне карт, а докладчик выбирал станции и прокладывал маршруты с пересадками. Видео его демонстрации опубликовано на ютубе, выглядит примерно так:

Вы нескоро увидите эти технические наработки: за два дня не пишут тесты и проверяют код менее тщательно. Это были эксперименты, но они станут основой для будущих улучшений MAPS.ME. Мы сделаем и навигацию по общественному транспорту, и отзывы, но точно не в том виде, как за эти три дня. Это только часть наших больших планов: приложение через полгода будет несравнимо с нынешним.

В перерывах между работой мы купались, жарили шашлык и бургеры, катались на велосипедах (не всем удалось миновать охрану и поехать изучать окрестности реки Яхромы) и сегвеях. Когда садилось солнце, кто-то увлечённо пел караоке, кто-то, уединившись, смотрел фильмы ужасов. Удивлялись безальтернативному меню ресторана и в панике тушили угли, пока ураган не швырнул их в деревянный дом. По пути домой с трудом не выезжали на автобусные полосы: несмотря на дни работы среди коллег, сложно было поверить, что за окном не воскресенье, а середина рабочей недели.

pole_climbers „Colour Coded OSM Notes“ – basierend auf dem Alter der Notes 1 | © pole_climber, uMap and map data © OpenStreetMap contributors ODbL

Mapping

  • Benutzer Chetan_Gowda schreibt in seinem Benutzer-Blog über die Umringe von 9,8 Millionen Gebäuden in 102 US-amerikanischen Städten, die Microsoft der OSM-Community bereitgestellt hat. Er behauptet, die Qualität sei gut. In den Kommentaren wird er gefragt, wie er zu dieser Einschätzung kommt.
  • Christoph Hormann erklärt, wie man Küsten und Gezeitenzone in OSM durch Nutzung aktueller und detaillierterer Luftbilder genau abbildet.
  • Jochen Topf kündigt eine weitere Maproulette-Aufgabe bezüglich „alter“ Multipolygone an, bei denen der outer-Way wie die gesamte Relation getaggt ist. Die Version 4.0 von OSM Carto behandelt diese Fälle übrigens anders als bislang üblich, wodurch diese Taggingfehler auf der Karte erkennbar werden.
  • Ein Mitarbeiter der Verwaltung des Müritz-Nationalparks hatte von Januar bis Mai in OSM zahlreiche Wege gesperrt und/oder gelöscht. Die Änderungen wurden mittlerweile zurückgesetzt. Siehe dazu die Diskussion im Forum.
  • Volker Schmidt möchte gerne wissen, wie man Verkehrsübungsplätze taggt. Es gibt noch kein Taggingschema dazu.
  • Joachim schlägt vor, places zusätzlich auch als areas zu erfassen. Die Idee ist, ein neues Tag boundary=place einzuführen und ggf. boundary-Relationen zu verwenden.
  • Malte Heynen schlägt vor, das Tag für parallel zu Hauptverkehrsstraßen verlaufende Fuß- oder Radwege um die Straßenklassifikation zu ergänzen. Router könnten so die Wege abseits vom Verkehr bevorzugen. Aus beispielsweise cycleway=sidepath soll nach dem Vorschlag cycleway=sidepath:primary werden.
  • Obwohl das Proposal Language information for name von Lukas Sommer mit 57 Prozent angenommen wurde, möchte er es neu formulieren. Er möchte noch klarer beschreiben, wie es sich auf Unicode-Namen auswirkt, wenn diese Information fehlt, und weitere Anwendungsbeispiele dazu liefern.
  • Tobias beschwert sich über den Missbrauch bestehender Tags durch die Mentz GmbH und deren intransparente Taggingpraktiken.
  • Die Insel São Jorge ist verschwunden – jedenfalls berichtet das Topo Lusitania am 09. Juni auf der portugiesischen Mailingliste. Offensichtlich konnte das Problem bis zum Redaktionsschluss dieser Ausgabe noch nicht behoben werden.
  • Polyglot möchte ein regelmässiges Webinar zum Mappen von ÖPV-Relationen mit JOSM und dem PT_Assistant Plugin starten. Los geht es am Dienstag, 27. Juni, 20:00 Uhr MESZ.
  • Pascal Neis hat seinen deutschsprachigen Vortrag von der FOSSGIS 2017 auf Englisch in seinem Blog verschriftlicht.

Community

  • Zusätzlich zum Veranstaltungskalender auf openstreetmap.fr gibt es auch noch eine uMap-Karte mit den Stammtischen, die Antoine Riche erstellt hat. Auf globaler Ebene gibt es solch eine Karte auch. Sie bezieht ihre Daten aus dem OSM-Wiki.
  • Ilya Zverv hat die Vorschlagsrunde (mit erster Abstimmung) der diesjährigen OSM Awards eröffnet. Im deutschen OSM-Blog fasst Michael Reichert die Mail von Ilya zusammen und hat die Beschreibungen der einzelnen Preise ins Deutsche übersetzt.
  • Im Rahmen der Partnerschaft mit der Gemeinde Dianguirdé im Nordwesten von Mali hat die Stadt von Ivry-sur-Seine das Dorf und seine Umgebung mit der Unterstützung von CartONG gemapped.
  • Ein Benutzer hat im deutschen OSM-Forum Teile eines Schreiben mit anschließender Vertraulichkeitsvereinbarung des Bundesverband der Energie- und Wasserwirtschaft e.V. veröffentlicht. Dem Verband seien Hydranten in der OpenFireMap (d.h. in OpenStreetMap) ein Dorn im Auge. Man fürchtet um die Sicherheit kritischer Infrastruktur. Die Reaktion der Community auf dieses Schreiben ist Kopfschütteln.
  • Simon Poole erinnert daran, dass es auf Transifex eine OpenStreetMap-Organisation gibt und man die Sichtbarkeit seines Projekts für Übersetzer erhöht, wenn man sein Projekt dort ergänzt.

OpenStreetMap Foundation

  • Auf der OSMF-Seite findet sich das Protokoll der Sitzung der Engineering Working Group vom 30. Mai.
  • Martijn van Exel fragt die OSMF-Mitglieder auf der Mailingliste OSMF-Talk nach ihrer Meinung zur Bewerbung von OSM France als Regionalvertretung.

Veranstaltungen

  • Sev_osm berichtet auf Twitter über zwei Workshops mit kostenlosen Tools für Mapping und Geowissenschaften (OSM, QGIS, GeOrchestra), die vom 12. Juni bis 24. in Niamey, Niger stattfinden. Diese Initiative wird unterstützt von “Les Libres Géographes (LLG)“, Projet EOF und OSM Communities aus Niger, Benin, Burkina Faso und Togo.
  • Am 15. Juni veranstaltete das Mapbox-Team in Peru einen OpenStreetMap-Workshop für Schüler der 4. und 5. Klasse an der Mariscal Caceres School in Ayacucho, Peru. Die Schüler staunten darüber, wie leicht Geodaten in OpenStreetMap hinzugefügt werden können.
  • OSM Peru hat an der „Konferenz über den Wiederaufbau bäuerlicher Genossenschaften“ (nach den verheerenden Überschwemmungen der vergangenen Monate) am 06. Juni in Lima, Peru teilgenommen.

Humanitarian OSM

  • HOT ist auch dieses Jahr wieder ein Kandidat unter den letzten 50 Organisationen für den $100.000-Preis des Drucker-Instituts der Claremont Graduate University.
  • Als Projekt des Katastrophen-Management-Tools InAWARE führte HOT zusammen mit vielen indonesischen Studenten Anfang Juni einen 3-tägigen Mapathon durch.
  • Open Global Exposure Database for Multi-Hazard Risk

Karten

  • Die neue Major-Version 4.0 von CartoCSS openstreetmap-carto wird für die Installation auf den OSMF-Servern vorbereitet. Es gibt zwar noch keine offizielle Ankündigung, aber Hinweise auf den Mailinglisten – etwa hier und hier. Der Stil soll vielseitiger werden; eine der großen Maßnahmen dafür ist die Einbindung von Vorverarbeitung in LUA.
  • HeiGIT (GIScience Heidelberg) hat das Katastrophen-Routing des OpenRouteService für stabil erklärt.
  • Das vom Grimme Online-Preisträger Lorenz Matzat begründete Unternehmen Lokaler hat die erste Beta-Version des gleichnamigen Editors veröffentlicht (Firefox/Chrome auf dem Desktop). Dieser konzentriert sich auf die Erstellung von Karten mit eigener Farbgebung und der Ergänzung von Anmerkungen für den Print- und Online-Journalismus. Das auf „vector tiles“ basierende Projekt soll nach der Beta diesen Herbst als Freemium-Angebot starten und u.a. SVG-Exporte ermöglichen. Eine Veröffentlichung des Quellcodes als Open-Source-Projekt ist für 2018 geplant. User Spanholz nennt noch andere Einsatzmöglichkeiten für das Tool: „I shared it also with my local police forces. They can now easily create maps for festivals or emergency situations, which can accurately show the area while highlighting more necessary informations.“ Das Video zum Tool.
  • [1] Benutzer pole_climber erklärt in seinem Benutzer-Blog, wie er eine uMap-Karte erstellt hat, die Notes anhand ihres Alters (letzter Kommentar) einfärbt.

Lizenzen

  • Die Stadt Mailand hat einige Trinkwasserspender von OSM importiert, daraus entsteht (it) (automatische Übersetzung) eine tiefgehende Diskussion über Lizenzfragen auf talk-it.

Programme

  • Jean-Maxime Fillau trug vor kurzem zum OSRM Projekt durch Hinzufügen einer Option bei, die garantiert, dass das Fahrzeug auf der richtigen Seite der Straße am Zielort ankommt. Dies ist besonders nützlich für große Fahrzeuge wie Lastwagen und Feuerwehrfahrzeuge.

Programmierung

  • Die Graphhopper GmbH sucht einen Freelancer bzw. eine Softwareentwicklungsfirma. Unter anderem sind Anpassungen an der Routing-Engine vorzunehmen.

ఉల్లాసభరితమైనటువంటి తీర ప్రాంతంతో విశాఖపట్టణం ఎల్లప్పుడూ నిత్యనూతనంగా మరియు ప్రశాంతంగా ఉంటుంది. నిత్యం అభివృద్ధి చెందుతున్న నగరంతో పాటు డేటా కూడా ఎప్పటికప్పుడు మెరుగుపరచడం అనివార్యం. విశాఖపట్టణంలోని కూర్మన్నపాలెం నా జన్మస్థలం అవ్వడం వలన, నాకున్న అవగాహనతో ఈ ప్రాంతాన్ని మ్యాప్ చేశాను. గతం లో ఇక్కడ మ్యాప్ చేయని ఆస్పత్రులు, ఎటిఎం'స్ ,సినిమా థియేటర్స్ వంటి ప్రాథమిక సౌకర్యాలు మ్యాప్ చేయడం జరిగింది. అభివృద్ధి చెందుతున్న పారిశ్రామిక ప్రాంతం అయినప్పటికీ జాతీయ రహాదారుల క్రమం సరిగ్గా లేకపోవడం వలన దీని మీద పని చేయడం జరిగింది. కాలంతో పాటు జరుగుతున్న పట్టణీకరణ మరియు వ్యాపారీకరణ గమనార్హం. పూర్వం మామిడి తోట అయినటువంటి ప్రదేశాలు కూడా పట్టణీకరణ వల్ల ఆధునిక అడవిలా మారిపోయింది. భవిష్యత్తులో పారిశ్రామిక మరియు గ్రామీణ పరిసరాలలో ప్రాధమిక వసతులని మ్యాప్ చేయాలనీ ఆకాంక్షిస్తున్నాను.

Visakhapatnam is full of life and buzz round the clock. The coastline has its own vivid panorama. Everyday is a new start with amazing developments, be it the pharmaceutical companies or automobile industries or the urban sprawl around Steel Plant. With the improving cityscape, the map data should also be equally updated and maintained. My area of interest was Kurmannapalem and how it gradually evolved over time. I mapped the main transport network, basic amenities like hospitals, ATMs and several recreation facilities which were not mapped in good detail before. A major concern was the impact of urbanisation and commercialisation. My locality which used to be a mango plantation is now a concrete jungle.

This is the link to go through.

Going forward, I would love to map the sub urban areas of Visakhapatnam which have major industrial units like Pharmaceuticals and also the basic amenities for the public.


Sharp Turns onto Ramps

Here's a map I got out of our Open Source Routing Machine when I built a validator for sharp turns onto ramps. The idea behind this validator is that turns onto highway ramps should never be sharp (i.e. < 90'ish degree). There is a high chance a turn restriction is missing at those locations.

Here's a map I got out of our Open Source Routing Machine when I built a validator for sharp turns onto ramps. The idea behind this validator is that turns onto highway ramps should never be sharp (i.e. < 90'ish degree). There is a high chance a turn restriction is missing at those locations.

With these checks enabled I found roughly 30k intersections on the planet. I visualized the results in the map below; the redder the circle, the sharper the turn angle onto the ramp.

In the results I found an issue that frequently re-occurred. Consider the situation below: heading east on Goff Mountain Road (the yellow line), there is a ramp on the right that you can legally take. Around the bend, there is another ramp onto the same road for drivers going west on Goff Mountain Road.

If you are driving east on Goff Mountain Road and happen to miss the ramp, re-routing will kick in. When generating a new route past the ramp that you initially missed, OSRM sees in the road network that there is conveniently a second ramp onto the same road. It then basically gives you the instruction to make a nearly 180 degree turn on the the next ramp! A turn restriction onto that second ramp from Goff Mountain Road would fix this issue.

Given that the navigation is able to pass in your bearings data (what cardinal direction you’re already moving in) to OSRM, OSRM won’t try and tell you to make a fast u-turn and try the first ramp again like in the third frame of the gif. Making a turn onto the second ramp isn’t considered problematic though.

There are definitely false positives in the data and cases you will never hit in reality. But there are also missing turn restrictions onto ramps that will result in bizarre instructions given back to re-routing requests.

And even though the sharp-turns-onto-ramps validator was just a quick evening hack it would be great to add more static road network property validators that detect situations like u-turns on high-speed roads or sudden changes in road class.


Spitze Winkel beim Abbiegen auf Ausfahrten

Hier ist eine Karte die ich mit unserer Open Source Routing Machine generiert habe als ich nach spitzen Winkeln beim Abbiegen auf Ausfahrten gesucht habe. Solche Abbiegevorgänge sollten niemals vorkommen und sind ein gutes Indiz für fehlende Abbiegeeinschränkungen.

Hier ist eine Karte die ich mit unserer Open Source Routing Machine generiert habe als ich nach spitzen Winkeln beim Abbiegen auf Ausfahrten gesucht habe. Solche Abbiegevorgänge sollten niemals vorkommen und sind ein gutes Indiz für fehlende Abbiegeeinschränkungen.

Hier ist eine Visualisierung; umso röter umso spitzer der Winkel.

Interaktive Karte

Ein Problem was immer wieder aufzutauchen scheint ist das Folgende (siehe Bilder unten): aus dem Westen kommend auf der Goff Mountain Road gibt es eine Ausfahrt auf der rechten Seite. Kurz nach dieser Ausfahrt ist eine zweite Ausfahrt für die Gegenrichtung.

Wenn man nun aus dem Osten kommend auf der Goff Mountain Road fährt und die Ausfahrt verpasst gibt einem die erneute Routensuche die Anweisung die nächste Ausfahrt der Gegenrichtung zu nehmen! Hier fehlt die Abbiegeeinschänkung in den OpenStreetMap Daten.

Der unmittelbare U-turn nach der Ausfahrt (drittes Bild im GIF) kann mittels Richtungseinschränkungen vermieden werden - für den Abbiegevorgang auf die Ausfahrt der Gegenrichtung benötigt die Routenplanung die Abbiegeeinschränkung.

Das ist natürlich der ungünstigste Fall und es gibt garantiert false-positives in den generierten Daten und Situationen die niemals solche drastischen Auswirkungen haben.

Вандализм от модератора Народных Карт Яндекса

Предыстория.

Не так давно у няковцев появился чат в Telegram. Так получилось, что в него набежали мы - осмеры. В ответ и в русскоязычный осмочат зашли несколько человек из чата НЯК.

Предыстория.

Не так давно у няковцев появился чат в Telegram. Так получилось, что в него набежали мы - осмеры. В ответ и в русскоязычный осмочат зашли несколько человек из чата НЯК.

История

Сегодня зашел разговор о необходимости и пользе модераторов в картографическом проекте. На что один из участников заявил, что "случайно" испортил данные OSM. Альтерна.тивный текст

Собственно по стилю видно, что признаваться сам он ни в чём не станет. И не стал :) я специально спросил у него, ответом было молчание. Теперь надо как-то найти вандала. Поиск по истории чата показал, что это один из народных модераторов яндекс карт по Свердловской области с ником alexfox. Собственно и в телеграмме ник тот же. Самое просто и очевидное было ввести этот ник в адресную строку

Но, естесственно, такого пользователя не оказалось, это было бы слишком просто. Следующий пункт поиска конечно Who's That?. Там я получил самое главное - uid пользователя 3656538. Следующий шаг - найти все правки пользователя, а заодно и нынешний ник. Теперь пора обратиться к оверпассу. Простейший запрос, прямо как в примерах на вики, и вуаля! Наслаждаемся остроумием школьника.

Получаем наглядно правки и новый ник sassos. Убеждаемся, что изначальное предположение не было ошибочным.

Что интересно: вандалить модератор яндекс карт в OSM начал ещё месяц назад, до нашего набега в их чат. Что послужило причиной умышленной порчи данных не ясно.
И ещё интересный момент: как только я всё это нашел, тут же показал в осмочате, но вандал сохранил молчание. Когда же я всё то же самое показал в чате НЯКа, человек сразу же признал что это сделал он и тут же извинился.

Вот как себя показал один из народных модераторов Яндекс карт. Выводы, как говорится, делайте сами :)

Несколько примеров потрясающего остроумия и юмора:

Вандальные правки откатил

I am thinking of bringing OpenStreetMaps.org in Tamil. Imagining a world, where a GPS device or smartphone, showing paths in Tamil and giving instructions in Tamil to the driver.

To achieve this, we need all the street names to be filled in OpenStreetMaps.org

I checked for the streets in my area, Tambaram, Chennai. Found that there are many street names are missing. Editing the street names on the browser seems difficult for the lazy me.

Was looking for any alternate ways to add streets in OSM. Found the Open Source android app “StreetComplete“.

It simply shows the streets that dont have a name and ask to enter a name for it. Thats all.

From the description of the app.

Help to improve the OpenStreetMap with StreetComplete!

This app finds incomplete and extendable data in your vicinity 

and displays it on a map as markers.

Each of those is solvable by answering a simple question to complete the info on site.

The info you enter is then directly added to the OpenStreetMap in

your name, without the need to use another editor.

As it says, it is really simple to add details like street names, road types, shops opening hours etc.

Install this app in your android phone and help OpenStreetMaps to have all the street names. It will lead to various super projects like “Maps in our language” and more.

Help to to build truely open maps.

Local government transparency in 3D

In September 2016, we launched Mapbox Cities to tackle cities’ biggest challenges through data-driven decision making.

In September 2016, we launched Mapbox Cities to tackle cities’ biggest challenges through data-driven decision making.

As a Mapbox Cities Featured Partner, the City of Melbourne’s Smart City Office set out to prove how tools and data can transform cities. The team started with experiments visualizing Melbourne’s open datasets to make data that’s available on their open data portal visually accessible to more people in the local community.

Watch an animated visualization of Melbourne's Open Data

The City of Melbourne is using cutting edge technology to share information with the people of Melbourne. They are not only focused on analyzing past events through existing datasets to learn for the future, but also are making potential future data available to their ‘users’ - the local community. They can then better understand and discuss what the city has in the works for them, thereby offering citizens an opportunity to influence the city’s decisions. We call this urban transparency 3.0!

The Mapbox Cities mentorship came just at the right time to power one of the City of Melbourne’s latest projects: The Smart City Office team created the 3D Development Activity Model (3D DAM), a tool which visualizes in 3D the current state of Melbourne, buildings under construction, approved developments, and applications for building permits for the next three years. The 3D DAM shows the local community how the City of Melbourne is changing over time.

Play with the model at developmentactivity.melbourne.vic.gov.au

Gathering feedback from the local community is essential to the work of the Smart City Office, but data as such may not be as accessible to the majority of the population as 3D visualizations are. Digital and physical spaces “for people to come together and collaborate on urban and civic innovations” are essential to create what MIT Professor Carlo Ratti calls an “innovation ecosystem” in smart cities created by engaged citizens.

A team of in-house engineers at the City of Melbourne’s Smart City Office developed the 3D DAM with technical guidance from the Mapbox Cities team. The team used our Maps APIs to host and serve Melbourne’s building data with our GL JS SDK to build the visual 3D interface. The result is an amazing city exploration tool, complete with 3D building hover highlights. This is essentially a minimal viable product (MVP) for a 3D city model of Melbourne, one of the cornerstones of the smart city strategy of the City of Melbourne.

We’re excited to see what the City of Melbourne’s Smart City Office comes up with next. Interested to learn more about Mapbox Cities and how your city can get involved? Sign up for our Cities newsletter.

pole_climber’s Colour Coded OSM Notes – displayed based on last edit date 1 | © pole_climber, uMap and map data © OpenStreetMap contributors ODbL

Mapping

  • User Chetan_Gowda writes a diary about Microsoft’s release of 9.8 million building footprint data of 102 cities, covering 44 US states, to the OpenStreetMap community. He finds the general quality of data being good and encourages the local communities to evaluate the quality for import. He is asked in the comment section why he considers the data to be of good quality.
  • Christoph Hormann explains how to accurately map coastlines and tidal zones in OSM, thanks to recent and detailed aerial imagery.
  • Jochen Topf announces another forthcoming multipolygon challenge, concerning “old-style” multipolygons with the same tags on both the relation and the outer way. As these are rendered differently with the 4.0 release of OSM Carto, they may be now noticeable.
  • Volker Schmidt asks how to map a “Verkehrsübungsplatz” – “Traffic training area”. Here is an example.
  • Joachim suggests to map places also as areas. The idea is to introduce a new tag boundary=place and, if necessary, to use boundary relations.
  • Malte Heynen proposes to tag foot and cycleways next to highways with their street classification. Routing engines could then prefer ways far away from the traffic. According to the proposal you would change cycleway=sidepath to cycleway=sidepath:primary.
  • Even though the proposal “Language information for name” by Lukas Sommer was accepted by 57% (26 votes), he will rewrite it, “to explain better, more detailed, what missing language information means for Unicode text strings, and how an example use case could look like.“
  • São Jorge Island in the Azores disappeared, reports Topo Lusitania on June 9th on the Portuguese mailing list. Obviously, the issue is still not resolved until the drafting of this edition of weeklyOSM.
  • User Polyglot wants to start doing regular Hangouts on Air about mapping of public transport using JOSM and the PT_Assistant plugin.
  • User marthaleena explains how she is mapping her hometown Visakhapatnam (Andhra Pradesh, India).
  • Pascal Neis published a blog post as a summary of his German talk (slides and video) (de) at the FOSSGIS & OpenStreetMap conference 2017 with the title “Detecting vandalism in OpenStreetMap”.

Community

  • Antoine Riche setup a map of regular OSM meetings in France: these are usually held monthly.
  • Ilya Zverev announced the “Call for Nominees” for the OpenStreetMap Awards 2017. There are some changes compared to last year’s process.
  • As part of its twinning with the rural commune of Dianguirdé in the north-west of Mali, the town of Ivry-sur-Seine mapped the village and its surroundings with the support of CartONG.
  • A user published in the German OSM Forum, parts of the letter, “German Association of Energy and Water Management e.V.”. Hydrants in the OpenFireMap (i.e. in OpenStreetMap) were a thorn in the side of the association. It is feared the security of critical infrastructure. The association disapproved of the letter’s publication. Readers may recall similar issues in the United Kingdom.
  • Simon Poole sent a reminder that an OpenStreetMap organisation entity exists on Transifex where you can now move easily your project for more visibility to volunteer translators.

OpenStreetMap Foundation

  • OSMF published the minutes of the Engineering Working Group’s meeting on May 30th.
  • Martijn van Exel informs the Talk-FR mailing list that the French OpenStreetMap association has made an application for local chapter status with OSMF. He asks the community to share any questions, comments or concerns.

Events

  • Sev_osm reports on Twitter about two workshops on using free tools for mapping and geoscience (OSM, QGIS, geOrchestra), taking place from June 12th to 24th in Niamey, Niger. This initiative is supported by “Les Libres Géographes (LLG)“, Projet EOF and OSM communities from Niger, Benin, Burkina Faso and Togo.
  • On June 15th, the Mapbox team in Peru conducted an OpenStreetMap workshop for 4th and 5th grade students at the Mariscal Caceres School in Ayacucho, Peru. Students were amazed to see how easily different geographic data can be added in OpenStreetMap.
  • OSM Peru participated in the “Conference on the reconstruction of peasant cooperatives” (after the devastating floods of the past few months) on June 6th in Lima, Peru.

Humanitarian OSM

  • The Drucker Institute at Claremont Graduate University has named the 50 semifinalists for the 2017 Drucker Prize, and HOT is one of them. The winner of the $100,000 Drucker Prize will be announced on September 29th.
  • HOT Indonesia hosts a mapathon with students from the University of Indonesia’s (UI) Department of Geography.
  • Fatima Alher tweets about a mapathon that took place on June 17th in Niamey (see “Events”). It was aimed, through this task, at mapping the surroundings of Diffa, Niger, an area affected by the Boko Haram abuses. See this announce on the HOT mailing list for details.
  • HOT has partnered with the Global Earthquake Model (GEM) and ImageCat on a Challenge Fund focused on developing a global exposure database for multi-hazard risk analysis. The Challenge Fund, formed by the Global Facility for Disaster Reduction and Recovery (GFDRR) and the UK’s Department for International Development (DFID) is aimed at building local and global resilience through innovation in order to better identify risk and enable more effective decision-making.

Maps

  • A major new release, 4.0, of CartoCSS is in the process of being rolled out on the OSMF servers. There is no official announcement yet, but many hints in the mailing lists, here and here. One of the big steps forward in increasing the flexibility of the style is the incorporation of LUA pre-processing.
  • HeiGIT @ GIScience Heidelberg released a dedicated stable disaster version of OpenRouteService (ORS) to support humanitarian logistics for Africa, South America and Indonesia with data from OSM.
  • Lokaler Editor, a browser-based tool for creating maps for print on the web, is now in beta stage. It helps journalists to create maps with their own design and enables them to add their own notes. The service offering is a freemium model with among others SVG export, and should start in autumn. The source code will be opened in 2018. User Spanholz named other possibilities for this tool: “I shared it also with my local police forces. They can now easily create maps for festivals or emergency situations, which can accurately show the area while highlighting more necessary informations.” There is a tutorial video as well.
  • [1] pole_climber published a very detailed blog post on how to create a colour coded map about OSM notes, displayed based on last edit date.

Licences

  • Milan municipality imported a few drinking fountains’ locations from OSM, therefore prompting (it) (automatic translation) a detailed licensing discussion on the talk-it mailing list.

Software

  • Jean-Maxime Fillau recently contributed to the OSRM project by adding an option to compute a route that ensures the vehicle arrives on the correct side of the road for the destination. This is particularly useful for large vehicles such as delivery trucks and fire engines.

Programming

  • Graphhopper is looking for freelancers or companies interested in implementing customizations of the GraphHopper routing engine, jsprit or integrating the GraphHopper Directions API in an application or process.

Other “geo” things

  • An international research team published an article on Nature about crowdsourced validation of land use data collected by remote sensing. They opened four campaigns on GeoWiki platform, analysed the variations in accuracy, and made the datasets available for further research.
  • The University of Heidelberg is looking for a Software Developer.
  • ResearchNReports published the Global Cloud GIS Market Research Report Forecast 2017-2021, a valuable source of insightful data for business strategists. It provides the Cloud GIS industry overview with growth analysis and historical & futuristic cost, revenue, demand and supply data (as applicable).
  • MapMyIndia claims to be India’s most comprehensive GPS navigation & tracking solutions provider, engaging the user on multiple platforms – mapping India years before Google Maps. While Google Maps is an app that allows users to visualise data, the data provided by MapMyIndia allows users to analyse a detailed array of geo-demographic data.
  • User ff5722 asks if there are really over 4.5 million km of roads in China. Several different estimation methods appear to confirm this figure. OSM only has mapped 1.2 million km of Chinese roads so cannot be used yet, to provide a more detailed analysis.

Rate of Interest According to Jagmohan Garg, the real estate market is greatly impacted by the rates of interest. It is recommended to research interest rates using a mortgage calculator, for anyone looking forward to buy a home with a mortgage. Any change in the interest rates directly determines a person’s ability to purchase a residential property. It has been observed that there exists a direct relationship between the interest rates and the cost to obtain a mortgage. As a matter of fact, the decrease in the interest rates reduces the cost to obtain a mortgage to buy a home. Consequently, this creates a higher demand for real estate and increases the prices. Thus, with the increase in interest rates, the cost to obtain a mortgage increases, which lowers the demand and prices of real estate. In the same way, with the cutting down of interest rate, the Real Estate Investment Trust (REIT’s) high yields become more attractive and their value goes up.

Economical Health The overall economical health is yet another important factor, which affects the value of real estate. Jagmohan Garg Delhi emphasizes that there are a number of indicators such as the GDP, employment data, manufacturing activity, the prices of goods, etc, which reflect the overall health of an economy. It is important to note, a sluggish economy leads to stagnancy in the real estate. Though, the cyclicality of the economy can have different effects depending upon the types of real estate. For instance, an economic recession is more likely to affect an REIT having a larger percentage of its investments in hotels, as compared to an REIT that had invested in office buildings.

Government Policies or Subsidies The demand and prices of property are also impacted by the policies made by the government. Mera Baba Group owner, Jagmohan Garg states that the tax credits, deductions and subsidies are the most common ways in which a government can increase the demand for real estate. Thus, it is important to know about the current government incentives for ascertaining the changes in supply and demand, and figuring out the potentially false trends. For instance, in order to increase the home sales in a stagnant economy, a first-time homebuyer’s tax credit was introduced by the US government in the year 2009. As per the National Association of Realtors (NAR), this tax incentive led to a substantial increase in the sales with over 900,000 people buying houses. Certainly, having a complete understanding of the key factors that drive the real estate market can help you in making the best investment decisions. It is also important for carrying out a complete analysis of potential investment options.
