ШТОСМ: Наш вкусный спонсор

Tue, 15 May 2012 19:06:19 +0000

Похоже, не только народные картографические проекты пытаются увлечь школьников. Оказывается, четвёртый год подряд всероссийскую олимпиаду по географии спонсирует Навител. Со всеми причитающимися бонусами: общими снимками на фоне логотипа и внедрением своих технологий в семьи победителей. Выглядит мило, но не могу не вспомнить, что до того, как я узнал и утонул в OpenStreetMap, я считал лучшей в мире работой (хотя и недостаточно денежной) ежедневные автопутешествия со сбором данных для коммерческих карт. Знают ли победители олимпиад, ребята, увлечённые географией, про альтернативу?

"OpenStreetMap.org User's Diaries": Pustell

Tue, 15 May 2012 18:08:25 +0000

This morning's ramble was the Robert Pustell Reservation. At 2:40 and 6 miles, it was a bit longer than I planned to be out; it's not that dog and I aren't up to it, but I have other things I should be doing.

The map is very nicely drawn, with lots of detail about paths, stone walls, and wetlands. The problem is, it's largely a work of fiction. There are a couple major trails that I just couldn't locate, there are a number of trails that aren't on the map, and the trails that are there often don't bear much resemblance to the map.

To be fair, it looks like the bikers have created a number of new trails. There are prominent yellow diamond arrows throughout, and some of the new trails go over fairly big drops. More problematically, there are banked turns and constructed jumps in a couple places. OTOH, someone else has laced the banked turns with brush and rocks, so it looks like there's some passive-aggressive push-back.

Tom Chance: Routing around pollution - any help?

Tue, 15 May 2012 09:38:45 +0000

While we’re benefiting from all this rain in London, which keeps air pollution at bay, I’ve been wondering about including pollution data in OpenStreetMap-based routing engines. The trouble is that I lack the technical skills to implement this, so I’m writing this post in the hope that somebody might be inspired to give it a go.

Another hazy air pollution episode in London

Air pollution is the second biggest cause of premature deaths in the UK after smoking. Here’s a little league table of nasties taken from Department of Health data:

Smoking – 87,000 premature deaths per year
Air pollution – 29,000
Alcohol – 22,000
Obesity – 9,000

The main pollutants in cities are particulates (PM₁₀, PM_2.5), nitrogen dioxide (NO₂) and nitrogen oxide (NO). Unlike the pea souper fogs of years gone by, these are invisible to the human eye but very deadly. They’re most concentrated on busy congested roads and around airports – so unsurprisingly in central London, around Heathrow and City airports, and in congestion hot spots dotted around the rest of London. We have some of the worst air pollution in Europe.

Long term exposure to these critters is obviously a bad thing, so it would be nice if we could find routes to walk or cycle without being affected. To some extent it’s just a matter of avoiding main roads, but some are much worse than others and in central London there are plenty of non-A roads that should be avoided as well.

WalkIt has a neat little feature that lets you choose a “low pollution” route. This basically tries to avoid roads with high concentrations of nitrogen dioxide. But it doesn’t cover the whole of the city, it doesn’t take account of nitrogen oxide or particulates, and it’s only for pedestrians.

So… who fancies taking the London Atmospheric Emissions Inventory maps, delivered in 20m grid shapefiles, and plugging them into one of the various OpenStreetMap routing engines to provide a walking & cycling “avoid polluted roads” option for London?

Bonus points could go to anyone who uses live data from the London Air Quality Network and Defra’s air quality monitoring web site (with its latest readings from a few monitoring stations) to give more or less priority depending on conditions.

Derick Rethans: Ignite London: Crowd Sourcing a Map of the World

Ignite London: Crowd Sourcing a Map of the World

London, UK

Tuesday, May 15th 2012, 09:47 BST

Almost two weeks ago, I gave a talk at Ignite London about OpenStreetMap, titled "Crowd Sourcing a Map of the World". Ignite's presentation style is 20 slides which automatically advance every 15 seconds. Having never done this before I actually wrote the whole talk out. The presentation that I gave slightly diverges from this but I thought it'd still be good to reproduce here. I did add some links to more information, and if you want to see the recording, you can find it at the end of this post.

1. This talk is about a project, started here in the UK with as its major goal to create a free map of the whole planet. From roads and motorways to country-side footpaths, restaurants and of course pubs. This talk is about OpenStreetMap, the free map of the world.

2. There are of course already plenty of mapping solutions available. Maybe one of the best maps can be acquired through Ordnance Survey. They can be regarded as the national authority on this subject. It's however expensive to get access to their maps, especially the very detailed maps from OS MasterMap. Additionally, it's only for the UK.

3. Besides the commercial solutions, you might wonder why we simply can't do with GoogleMaps? It's mostly freely available for use and also provides you with satellite imagery and StreetView. They even allow you in some areas to update the map through Google MapMaker.

4. But one thing Google doesn't give you access to, is the data behind the map. All you will ever see, is the rendered map tiles and perhaps some APIs to lookup locations and points of interest. Even for data that you have added yourself through MapMaker.

5. Both aspects; the cost of commercial maps, as well as the access to the data that is behind the map tiles is something that the OpenStreetMap project addresses. But which steps have to be taken to obtain this enormous amount of geographical data?

6. We start by getting our wellies and trusty GPS out. Maybe even some pen and paper. We find a location that looks rather empty on the map and travel to that area to see what's on the ground. This is step one: data gathering in the field.

7. In urban areas such as London the roads have often already been mapped and a GPS is not accurate enough to be useful. Then we just use pen and paper to record points of interest, such as shops, landmarks, restaurants and postboxes, my personal favourite.

8. In the country side, donated aerial imagery makes it possible for us to easily trace tracks and footpaths. However, you can't be sure whether the imagery is up-to-date, and you can't always see where fences, streams and local wild life create barriers.

9. In both situations, surveys are best done in groups: at mapping parties. It helps spread the workload and a larger area can be surveyed in one go. As an additional benefit, it allows us to go the pub and discuss our mapping adventures!

10. Doing a survey is important. We take photographs, video and notes with pen and paper of everything that seems to be of interest. This leaves a record that everything we map is actually existing and we can prove that nothing has been copied from other copyrighted maps.

11. After collecting the data, we enter it into the database. This includes basic information such as street names, but we also record whether a café has wheelchair access, or whether a pub has wifi. Updates to the map show up on the site close to real time.

12. Every map object has tags associated with it. Tags tell whether a line is a road, or perhaps a fence. All the tags are free form so you can generally add as much information about an object as you want. Sometimes however, this gets slightly out of hand and people tag pandas in trees and eyes on postboxes.

13. Once the data has been added to the map, we can make use of it. One of the primary uses is obviously showing the data as map tiles. But with all the extra data, we can generate maps that show all the information you're interested in-and nothing more.

14. Clockwise, we have four different visualisations of the map data: we have a cycling-specific style, a style that shows transport routes, a rendering with MapQuest's style sheets and even a water colours inspired style.

15. Having mentioned MapQuest; they were one of the first companies to make use of OpenStreetMap data. They provide, free of charge, map tiles with their own rendering style as well as an instance of Nominatim, OpenStreetMap's geolocation sister project.

16. Lots of companies have already switched to OpenStreetMap. The property search site Nestoria recently switched from using GoogleMaps to OpenStreetMap. Partly because of their costs, but also partly because "The maps are equal or better". geocaching.com, TfL's countdown website and Apple also use OpenStreetMap maps and data.

17. Although OpenStreetMap provides a free and editable map of the world, there are certain requirements for using the data as well. The most important one is that you always need to attribute the OpenStreetMap project.

18. In order to help people start using OpenStreetMap for their mapping needs, the Switch2OSM site has been launched. This website provides background information, case studies and technical information on how to use OpenStreetMap data.

19. Right now, OpenStreetMap has very good data coverage in the country, but we are not nearly finished. A lot of work still has to be done, and we rely on you to improve the data too, even if you add just a postbox.

20. In the last 5 minutes we have looked at what OpenStreetMap is, how the data is gathered and how the data is added to the map. Further more, we had a look at different use cases of the data. OpenStreetMap in the UK: Footpaths and pubs a speciality!

And then I planned showing the "Year of Edits" video, but that sadly didn't work out. I'm including it for good measure here though. (If you want it in HD, follow the link).

ШТОСМ: Рот наросхрыст, язык на плячо

Mon, 14 May 2012 21:04:35 +0000

В апреле участники белорусского MapMaker решили в очередной раз договориться, на каком языке писать географические названия. На беду, известный активист Игл назвал тему «Как сплотить комьюнити?» После такого заголовка совершенно закономерно, что в итоге меньше, чем за неделю, все перессорились, а тема, вопреки попыткам некоторых участников выдержать линию обсуждения, скатилась в знатный роддом мемов и музей образцового использования белорусского языка. Особенно великолепны «Это письмо в семи главах» в середине второй страницы и «Куды заносіцца нарматыўная транслітарацыя?» в начале третьей.

Увы, языковой вопрос так и не был закрыт: жар темы привлёк какого-то индуса с непроизносимым именем, который а) залочил тему; б) сообщил, что по всем вопросам пусть ждут официального решения гугла. С какой скоростью последний принимает решения, мы все знаем (вернее, не дождались ещё ни одного). Никто даже не икнул. «А можа, так яно и трэба?»

CycleStreets: Cycling on the national stage

Mon, 14 May 2012 16:25:08 +0000

The last few months have seen a big resurgent movement of people wanting to see better cycling conditions around the UK. We couldn’t let this pass without some brief comment!

Cities Fit for Cycling – Times CycleSafe

The Times newspaper has been running a fantastic campaign, Cities Fit for Cycling, which has massively raised the profile cycle safety issues, with its 8-point manifesto that echoes many of the key issues often raised by cycle campaigners.

As a search for #CycleSafe on Twitter will show, Cities Fit for Cycling has really captured the imagination and interest of cycle campaigners – and increasingly the general public – around the UK, and especially in London.

A series of articles has really upped the pressure on decision-makers, leading to parliamentary debates, and London Cycling Campaign have helped pile on the pressure by organising The Big Ride.

Through our own project Cyclescape we are hoping to enable the enthusiasm of campaigners to be facilitated more at a local level.

Summer of Cycling

This summer sees the Summer of Cycling. It’s a great opportunity to encourage someone you know to get on their bike!

The Summer of Cycling is a national campaign running this summer which aims to encourage more people to cycle. The All-Party Parliamentary Cycling Group and The Bicycle Association, alongside the force of 23 cycling organisations are aiming to double cycling this summer.

It’s about encouraging everyone with an interest in cycling to share the fun and introduce just one friend, neighbour, colleague or family member to cycling.

Who’s your +1 ?

Go Dutch! says London Cycling Campaign

London is seeing a resurgence of interest in the idea of Going Dutch, thanks to cyclists led by London Cycling Campaign, of which we are proud to be members, and others.

LCC have done a brilliant job over the last year in challenging decision-makers to do better in places like Blackfriar’s Bridge and Parliament Square, and to do what virtually no other group has done, and actually showcase actual alternative designs, putting forward a wonderfully positive agenda. From our own experience in cycling around the Netherlands, we know how much this would benefit every Londoner, and so we fully support LCC’s efforts.

Have a look at more Photos from the Netherlands in our Photomap, some of which were from our own trip with Cambridge Cycling Campaign.

We hope some of the above will inspire you to get more involved, wherever you are!

Mappa Mercia (UK Midlands): More canals than Venice?

noreply@blogger.com (Mappa Mercia) — Mon, 14 May 2012 14:40:00 +0000

“More Canals than Venice” is something you’ll hear often in Birmingham or from Brummies anywhere, to describe the city. It’s mostly a defensive mechanism, I believe, because Birmingham does not enjoy the best of reputations in the nation’s affections and is the butt of many a joke. It’s repeated incessantly, completely oblivious of perhaps better claims from cities like St Petersburg or Amsterdam, which have the added advantage of being much higher in the tourist destination stakes than Birmingham. (Though curiously one of the few boom sectors in Birmingham is hotel construction, with increasing numbers of visitors filling the rooms once they’re completed.)

Perhaps those with the database skills could analyse the OSM data and settle the argument once and for all – which city does have the most canals?

However Birmingham does have one unique claim to fame: a canal roundabout at the junction of the Birmingham and Fazeley Canal and the Birmingham Canal Navigations. And yes, it is tagged with junction=roundabout, although I don’t know whether the direction is correct as I’m not a boat navigator and don’t understand the “rules of the road” for boats. There are certainly no oneway signs present. And I’ve never been present when boats are going round it so I haven’t seen which direction they take.

Birmingham’s canals were built for commercial heavy-lifting during the Industrial Revolution and until fairly recently were woefully neglected. There are still large stretches which pass through industrial areas which can be pretty grim waste-strewn and graffiti-heavy thoroughfares. In contrast, around the City Centre there have been lots of developments of waterside apartments and cafés and nightspots using the canals as an attraction. You have to understand Birmingham is one of the few cities in the world not sited on a major river so water has a special attraction for the city’s inhabitants and visitors. We even have a waterbus which plies the short distance from the Mailbox (an upmarket shopping mall) to the NIA (National Indoor Arena – a major indoor sports and event venue). It’s mainly used by tourists: locals find it quicker and cheaper to walk.

It makes a strange journey to cross the city via its canals, avoiding the traffic and not being aware of the usual landmarks. All your usual mental landscape of knowing where you are evaporates and you look at the city in a new way. On the subject of avoiding traffic, the canal towpaths make excellent cycle routes and are used regularly by the city’s cyclists.

If you visit Birmingham, take half an hour to descend from its streets to wander along its canals – you’ll come away with a much better impression of the city – not comparable perhaps to Venice, but better than when you arrived.

"OpenStreetMap.org User's Diaries": WOF#4. Database server load

Mon, 14 May 2012 12:10:28 +0000

I want no offence. Forgive me if I speak wrong. I state my mind in best words I find. If I fail to find words please help me. Not say "go away and stop critics".

I try to fix worst things. First I thinked they were tags. Trying to fix tags I found larger issue. I will no more fix tags without approval. I got idea of "Caring community preview" proposed by user Matt. I want not my posts to be read as "justification for unaccepted edits". I want my edits accepted. But when unacceptance reasons are technical, I want fix technical reasons, not get "no do not just because".

User woodpeck said "Ten guys like WorstFixer and we can fill a separate $15000 database server just with the likes of him". Think: ten users can kill $15000 server.

I respect system administrators. They do good job.

But looks we have worse problem than database bloat. Database server IO load. I read wiki and munin. Here is how it looks it works.

Ramoth is main OSM database server. It is not cheap. But it is upset. And users are angry about it.

OSM Database server not calculates. It stores, reads and writes data. So it needs not to have lots of CPU. CPU is not used. Look:

It uses 2 cores at most. And look on top of graph. It always waits for IO. All it can do is wait IO. And do nothing. And be upset.

Here is how it waits for data:

Midnight spikes are some database cron jobs. I think they show top of possible performance.

Slowness comes if it needs to read faster. And it almost reaches top load when usual people edit. Not even WorstFixer.

Here is list of things I propose:

1. $0. Calculate statistics.

I want daily update of database table sizes. So people can really see data base bloat. And maybe start fixing code if it is really issue.

To do this, system administrators need add results of this query to http://www.openstreetmap.org/stats/data_stats.html page.

SELECT nspname || '.' || relname AS "relation", pg_size_pretty(pg_total_relation_size(C.oid)) AS "total_size" FROM pg_class C LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace) WHERE nspname NOT IN ('pg_catalog', 'information_schema') AND C.relkind <> 'i' AND nspname !~ '^pg_toast' ORDER BY pg_total_relation_size(C.oid) DESC;

2. Move all frequently accessed data to SSD.

There are already SSD in server. But less than half of it is really used. It is used to speed up read of some regions of disk. Needs checking what it actually stores. I afraid it stores GPS Points for Germany and not map data.

2a. $2000. 2xIntel® SSD 320 Series 600GB.

Decide which tables can fit into 600 GB array of two mirroring SSDs. Move all index to it. Preferably move all current_ tables if fits. Needs no rails code change. Just database table spaces.

2b. $1000. 1xIntel® SSD 320 Series 600GB.

Reorgznize disks. Use only 1 SSD disk for CacheCade. Use two other as in 2a.

2c. $600. 1xCrucial 512 GB SSD.

Reorgznize disks. Use only 1 SSD disk for CacheCade. Use 512 GB disk for that. CacheCade not uses more anyway. Use two other as in 2a.

If you like this proposals, you can donate to openstreetmap. http://donate.openstreetmap.org/ is easy. If OSM has money specially marked "for disks" it will surely buy better disks.

Are my calculations flawed? I want comment from OSM administrators, if possible. And any other opinion.

"OpenStreetMap.org User's Diaries": Как мапить? Просто мапить!

Sun, 13 May 2012 21:27:28 +0000

Вот Буки, Житомирская область. Оказывается довольно интересное место и покатушки туда устраиваются. А на карте (осм, конечно) белое место! Блин. ну еще Россия с огромными пространствами, но тут где все перепахано вдоль и поперек.... Белое пятно.

Начал по космоснимкам с дорог: 1) более всего востребованы в реальном применении; 2) просто распознаются и 3) просто рисуются. Черт, именно последний пункт и становиться к несчастью определяющим. Просто!

Все потому что -- ОСМ это любительская картография. Не по профессионализму, по возможности время уделить. Т.е время выделяется урывками и в этом режиме совсем другие приоритеты и в первую очередь простота. Просто, значит быстро. Просто значит не сложно, значит 5 минут на изучение и 40 минут на созидание, 40 мин на нанесение на карту объектов.

И в этом есть удовольствие исследователя, открывателя. Есть дорога значит можно отрисовать маршрут, значит можно потом выпутаться, выехать.

Вот немножко дорог по Буки сегодня отдал (Житомирская обл). Попробовал землепользование обозначать через отношение -- забросил, трудоемко и не очевидно. А дороги всегда востребованы. И их просто рисовать. Тем более где кроме точки больше ни чего на карте нет.

Нарисовал. Получил удовольствие. Отдал на сервер. Отдал людям. Получил удовлетворение. Дополните. И вы получите такое же удовлетворение.... :-;

Why grey revert? Reverting store is cheap. "Version 1 is same as version 3". You keep current version in current data base and just pointer in archive.

Look closer at archive and visible separation:

It is sane way to do servers for OSM. You need not tell contributors not to contribute because of large database. Real users need archive part not.

"OpenStreetMap.org User's Diaries": Schnelles und einfaches Aufzeichnen von Tracks mit etrex 30

Sat, 12 May 2012 21:53:17 +0000

Ich habe mir diese Woche mit einem etrex 30 mein erstes Garmin gekauft. Ich möchte das etrex hauptsächlich zum biken mit openmtbmap brauchen. Da openmtbmap auf OSM basiert möchte ich mithelfen fehlende Wege und Strassen einzutragen. Dafür möchte ich selektiv Tracks aufzeichnen.

Nun sind wir bei meinem Problem: Es ist ziemlich kompliziert auf dem etrex von der Karte die Trackaufzeichnung zu starten. Um den Weg zu verkürzen habe ich mit Seitenfolge das Einstellungsmenue auf eine neue Seite gelegt. Nun habe ich folgenden Weg um die Trackaufzeichung zu starten: Karte -> back, back -> Joystick runter, runter- > Joystick -> Joystick -> ein oder zweimal runter-> Joystick -> back, back -> Joystick

So nun habe ich nach elf Interaktionen die Trackaufzeichnung eingeschaltet und bin zurück auf der Karte...

Ich möchte nur einzelne Wege aufzeichnen, zB. solche die auf OSM nicht eingetragen sind. Und das möglichst so einfach dass man da während des Fahrens machen kann.

Gibt es eine Möglichkeit das einfacher zu machen? zB. Mit Apemap auf dem iphone brauche ich genau vier Interaktionen... Klar das Garmin hat einem Smartphone gegenüber andere Vorteile: Regenwasserdicht, längere Akkulaufzeit, und das Display ist bei wechselnden Lichtverhältnissen besser ablesbar...

Die Frage ist nun: gibt es eine Möglichkeit die Trackaufzeichnung schnell und einfach ein und auch wieder auszuschalten? Gibt es vielleicht einen Hack? Es ist mir auch egal wenn ich beim etrex die Garantie verliere... Weil so kann ich das Gerät nicht so einsetzen wie vorgestellt und ich muss mir überlegen ob ich's in's Ebay stellen will...

Bin über jeden konstruktiven Vorschlag froh. Gruss Snifi

"OpenStreetMap.org User's Diaries": Öschinger Klufthöhle

Bisher haben wir die Daten für den genauen Ort der Öschinger Klufthöhle nur aus dem Geoinformationssystem des RP Freiburg extrahiert. Bei der heutigen Besichtigung des Ortes selbst sind wir dann 10m dran vorbeigelaufen. Also geht es am Sonntag wieder in den Wald hinterm Freibad - zum exakten Einmessen.

ШТОСМ: Фонд + премия

Sat, 12 May 2012 13:20:30 +0000

OSMF объявил о создании Фонда памяти Ульфа Мёллера (известного участника, погибшего в январе). Средства из него пойдут на «продвижение OpenStreetMap». Учитывая, что счёт фонда тот же, что и у обычных пожертвований, последние даже с основной страницы идут в фонд памяти.

Кроме того, учредили Премию имени Ульфа, которую будут вручать раз в год единственному участнику, который по мнению большинства больше всех помог проекту. Как и со стратегией перелицензирования, на мой взгляд, здесь OSMF несколько недодумал. Можете вы назвать одного человека, который помог OSM в масштабах всего мира в прошлом году? Не двух, и не того, что заметен только в русскоязычном сообществе. Отобрав несколько кандидатур, мы с большой вероятностью обнаружим, что они не нуждаются в очередном подтверждении своей полезности сообществу и карте (есть же лолкот), и кого стоило бы поддержать на самом деле, так это менее заметных людей, кто каждый день рисует карту, собирает треки и улучшает инструменты для мапперов. Их, правда, сотни — но значительно меньше, чем хотелось бы.

Четыре месяца назад порадовались, что нам выдали в свободное пользование кучу неплохих (жаль, чёрно-белых) снимков OrbView-3. ГИС-Лаб написал пару статей, любители попробовали привязать пару снимков — и всё заглохло: слишком сложно. Но сейчас началась движуха: иностранцы уже вовсю делают покрытия целых стран, выдавая удобный для работы TMS.

У нас же есть Александр Зейналов, который не поленился написать цепочку скриптов и настроить mapserver на серверах Рамблера. Загрузил пару самых вкусных снимков — и вы можете подключить их в JOSM (как WMS). Подробнее про всё написано на странице проекта, там же есть ссылка на карту, где можно посмотреть покрытие и уже загруженные снимки. Для добавления новых фотографий скачайте их, выложите куда-нибудь и дайте ссылку Александру. Так обведём!

"OpenStreetMap.org User's Diaries": 鈴鹿山系御在所岳

Sat, 12 May 2012 00:39:23 +0000

三重県滋賀県境にある鈴鹿山脈の代表格である御在所岳を、三重県側からマッピングしました。もともと Yahoo/Alpsmap のインポートデータがあったのですが、GPS データとかなりずれているようだったので、Bing 写真を参照しつつデータを修正しました。山上公園の舗装路は highway=residential でマップされていたのですが、residential はふさわしくないが、track でもないだろうとちょっと悩んで highway=service に替えました。

ロープウェイやリフトは Mapnik ではレンダリングされませんね。名前だけが表示されていますが。

登山道名は過去に登った知識で入力しましたが、いつか GPS を持って歩いて登りたいものです。また、新しくできた「一の谷新道」の入り口だけ確認しましたが、これは Yahoo/Alpsmap にもなさそうです。これはなかなか楽しそうな登山道なので、いつかそのうち機会があったら登りたいものです。

私の GPS には気圧に基づく高度計がついているので、あらかじめ既知の場所で校正して登りました。誤差は 20 m くらいはあるような感じですが。アップロードした GPS track にはそのデータも含まれています。GPS による高度と気圧計による高度が併記されています。このデータを簡単に活かす方法はあるのでしょうかね。

山頂は一等三角点の他に、「こちらが本当の山頂」と言われる場所があります。そちらから見ると一等三角点がやや下に見えます。高度は山頂には表示されておらず高度不明ですが、そちらにも natural=peak を打ってみました。拡大した時はそちらも表示されてほしいですが、低倍率では一等三角点が表示されてほしいところです。富士山など、山頂に複数のピークがあるのはよくあることですが、これが倍率ごとに綺麗に表示されるとありがたいですね。何らかの方法でグループ化してこれが主峰、と指定する方法はあるのでしょうか?

CycleStreets: CycleStreets Mobile web site judged “Best Application Design” by usability expert

Fri, 11 May 2012 22:17:15 +0000

We’re delighted that the CycleStreets Mobile web site has been judged one of the “Best Application Designs”, by renowned web usability guru, Jakob Nielsen!

The mobile site was one of the winners in the Lightweight Applications category. You can read the report announcing the winners on his site, and a fuller downloadable report is available (for a fee).

The site is a small-screen version of our main site, and is intended to work on a range of mobile devices, such as iPhone, Android, modern Blackberry devices and more. (We haven’t quite got full compatibility for Windows Phone 7.5 Mango yet, but if you can help, do contribute to the codebase.)

As the report outlines, our aim with producing a mobile web browser app was to enable quick and simple planning of journeys on a small screen, offering the key functionality of CycleStreets with a minimum of fuss, a quick download time, and providing clear large buttons. We were able to include much of the usability learning from the main site and the iPhone and Android apps in creating the site, and as such it includes many of the best elements of each of them. For instance, there is a quick way to switch routes directly and to see the details of the route without going to a different screen. Also, the crosshairs concept enables quick and accurate planning and avoids problems with large fingers obscuring the start/finish points.

The site was created by Anna Powell-Smith, who we’d like to congratulate! We’d also like to thank Tom Steinberg of MySociety whose insight into one key aspect of the app really helped improve it.

I listen to you attentively. I put notes.

Why no mailinglist post?

Won't work. Ever. Maybe only if you write that to dead local mailing list. Where nobody reads anyway.

Have a look at our license change. Workflow #1. When the fuck will they finish?!

I propose alternative. It is not ideal. Nobody is ideal. But it will work. Because it needs people with editors. Not bureaucrats with mail boxes.

I work on scheme #2, until someone proposes better option in non-blocking discussion.

ШТОСМ: Элементарные вещи

Fri, 11 May 2012 15:49:55 +0000

Несколько дней назад PShA выложил на гитхаб несколько плагинов к Leaflet, часть из которых уже используется на openstreetmap.ru: загрузка GPX и KML, полоска масштаба и ссылка на карту. Моя попытка их использования обломалась: кажущаяся простота библиотеки оборачивается ужасом для казуального программиста из-за отсутствия документации и примеров. Вроде, простая задача: показать для каждого примера от OpenLayers, как быстрее и проще сделать его на Leaflet. Это тяжелейшее бремя ещё ожидает своего программиста, но Павел осилил-таки написание примеров для своих модулей. Наконец-то можно сделать отображение трека без жонглирования проекциями.

У самой библиотеки, кстати, есть страница сбора пожеланий. Первые места там ожидаемо занимают подписывание и кластеризация маркеров, а также векторное рисование.

Mappa Mercia (UK Midlands): Birmingham: the less glamorous side

noreply@blogger.com (Mappa Mercia) — Fri, 11 May 2012 13:40:00 +0000

Regular readers of this blog might have the impression that Birmingham is filled with splendidly maintained examples of architectural heritage, as I try to liven up mapping on the ground by centering surveying trips around them.

Nothing could be further from the truth.

Owning a listed building is an onerous (i.e expensive) undertaking. Whilst wealthy businesses and individuals, and large state institutions can enjoy the prestige that occupying such buildings confers upon them, for others it’s more of a struggle. Often the National Trust or English Heritage have to step in and rescue buildings that are in peril. But their budgets are not limitless so few can be rescued in this way. Birmingham Civic Society also does its best to preserve listed buildings that are in danger within the City, but with even more limited funds.

Not only are owners restricted on how they can adapt and extend their buildings, in order to maintain their architectural integrity, but they are often restricted to using original materials. Original materials are rare or non-existent and have to be specially manufactured, sourcing both of which is expensive. Then craftsmen skilled in using such materials have to be found and hired, again at premium rates. All this makes the planning process even longer and more complicated than usual, adding to project timelines and costs.

It’s not surprising then that some owners just give up and let these building slide into decay, as some of these pictures show. The building covered in scaffolding is to prevent it collapsing, not an indication it's being refurbished. The buildings shown here are all within a 5 minute walk within the Jewellery Quarter, which las led to a whole area becoming blighted as far as development is concerned. (Generally the Jewellery Quarter’s large and varied population of listed buildings is very well-maintained and has been the subject of previous blogs ). Trying to persuade developers to enter such areas is yet another headache suffered by City Council planners.

The cynical amongst us might well suggest that the owners are hoping that the building eventually has to be demolished purely for safety reasons, which then gives them a free hand to develop the site

Chris Hill: Fire hydrant locations are confidential

noreply@blogger.com (Chris Hill) — Fri, 11 May 2012 10:29:00 +0000

Strolling around the village I saw a man working in the street. The van had a Humberside Fire and Rescue logo and the man was fixing a hydrant sign to a wall. A quick chat established that he was checking they were present and replacing imperial hydrant signs with metric ones. I asked him if any data about the location of the hydrants is available. He said he would ask someone to call me about it.

A little later I got a call from HF&R. I asked if the location of fire hydrants was available and was told in no uncertain terms that they were not. I explained about OpenStreetMap and the caller told me that OSM had no reason to add hydrants, adding that their locations are confidential. When I said that as the data is not available I would just continue to add the ones I see as part of surveys he repeated that their locations are confidential and added that they belong to Yorkshire Water, the local water company. He asked why I wanted to put hydrants into OSM and I told him that such details make a richer map.

The locations of hydrants are hardly confidential, there is a yellow sign showing where each one is. I was a bit surprised by the HF&R man's indignant reaction. It does seem that the notion of opening up data has not reached into that public body at all.

I have only added a few hydrants experimentally and stopped because it didn't seem worth the effort. I may add a few more, but not, it seems, based on HF&R data, and only under the cover of darkness.

"OpenStreetMap.org User's Diaries": Worst OSM Fixer

Fri, 11 May 2012 00:00:50 +0000

Problem of OSM is graphomania.

People want to write.

To write long books about openstreetmap.

To write long threads on openstreetmap. Even longer to prevent disputes.

When someone imports loads of shit, they keep silence.

When someone posts pictures of that, they laugh and make fun.

When someone fixes that, they ban him.

Nobody ist perfect. Ich am not.

I not wanted to write this post. But I have 24 hours free time to think. I was banned, and will be banned in future if laws not change. If you want to fix something in OSM you have to be graphomaniac. You will write tons of letters to change tens of objects.

That sucks.

I was told to announce so I announce.

is_in tag is_indikator of bad import. Look yourself at taginfo. If object author used is_in tag instead of Karlsruhe scheme he did his import carelessly.
ele tag is another bad import indikator. Look yourself at taginfo. ele=0 ist used on carelessly imported parkings, and non-touched GPS way points. I am not saying anything about http://taginfo.openstreetmap.org/keys/ELEVATION which sucks too.

For that reasons, I declare:

I will not upload any object with is_in tag. I will remove that tag. Not to lose data I will store all data from it into Karlsruhe schema.
As first thing after ban finishes, I process all un-elevated objects. Remove ele=, latitude=, longitude= tags. See what to do with other.
Ich want no war. OSMF und DWG will ban me if Ich edit too fast. I will wait for all the bans to finish. They limit maximum speed. I limit minumum speed. Ich set minimum speed fur mich as 50 000 nodes a day. If Ich edit 100 000 objekts per ein day, it is O.K. to ban me for day. If 150 000 - for two and so on. No more please, if you want no war too.
Being Worst OSM Fixer, remembering that OSMF promised to never tell anyone who Ich really am, Ich collect any letters and tweets about shit-imports, bad tags und other fixable stuff.
I promise to never tell any one who you are. Show me things you dislike. If thing you show me convinces me that all is bad there, I will fix it.
My twitter ist https://twitter.com/#!/WorstFixer und Ich read it.

"OpenStreetMap.org User's Diaries": Hacker Bus: Mapping Party in Paraty, RJ, Brazil

Tomorrow morning (Friday, May 11th) the hacekr bus will leave São Paulo in another trip, this time it is the city of Paraty, Rio de Janeiro for the event Virada Digital

As part of the many workshops(15 and counting) and hacks that we will be doing during the trip and while there, such as the file share market, data scrapping with python and others, there will be a Mapping Party too. We plan to improve OSM for that area and gather more contributors/teach how to use the tools.

If you live nearby or know someone that will be going to the same event, please share the invitation. The time and details of the mapping party will be fixed in a flipchart with the bus, that will be parked most of the time between the "Hub Estrela" and "Hub Dome".

CycleStreets: Cyclescape: More features in place

Thu, 10 May 2012 19:40:09 +0000

Cyclescape is the toolkit for cycle campaign groups that we’re developing. Here’s the latest update, cross-posted from the Cyclescape blog:

Work is continuing apace with Cyclescape, with more features now in place as we work up to a wider release to Campaign groups around the country.

There are still quite a number of unfinished areas, but we’re getting there. Andrew and (most recently) Andy have been busy adding more in place for us.

Deadline setting
Collision data
Per-thread attachments
Committee-only privacy setting
Popular issues

Read about these below:

Deadline setting:

Deadlines (or other dates) can now be set.

Our experience of cycle campaigning is that it’s often easy to miss a consultation deadline or some other date, if there’s a lot going on. By then, it’s too late, and the opportunity to see improvements to cycling are missed.

The set dates are now listed in ‘My Cyclescape’, the user’s main summary area. We’ll be developing this interface further.

Collision data:

Collision data is now integrated, using a new data feed from CycleStreets, and linking through to their collision reports.

This feature has been developed for the Cambridge group, pushed forward because of the large number of planning applications in that area, for which collision data can often provide a useful context.

Development of this feature, and various underlying code pre-requisites, has been possible thanks to a grant from Cambridge Sustainable City, whose support has been invaluable.

This screenshot, for instance, shows the site of collisions in Mill Road, an area subject to continuing pressures on cyclists from lorries. Several planning applications in recent years would have benefitted from this data being available.

The finalised interface for collisions isn’t quite in place yet – buttons for this will be added to finish it off.

Per-thread attachments:

Attachments can now be added to individual discussion threads. Previously the only way to add an attachment was to add it to the Library, which is always public.

Currently there is a slight limitation that, if e-mailing to the discussion thread (since you can reply to things via e-mail, not just via the website), attachments do not get through. We’re working on this!

Committee-only privacy setting:

There are now three privacy options for each discussion thread:

Public (publicly visible)
Group (i.e. available to all members of the group)
Committee (available only to current Committee members)

The latter option means that groups can discuss sensitive matters in privacy if required, e.g. pre-consultation plans from a developer.

There is a setting in the group’s area which sets the default (public/group) when their members start a discussion thread.

Popular issues:

Cyclescape has a voting system, which now results in a list of popular items, ensuring that key strategic issues can stay floated to the top.

More will be done to expose this feature in due course, as the rest of the interface is improved, but the underlying functionality is now in place.

The What’s New? link at the end of each page on the site has a log of individual features and bugfixes as they are put in.

Bit by bit, the site’s functionality and interface is falling into place!

In our next Cyclescape blog post we’ll talk about what we’re currently working on, i.e. what’s missing and what’s not yet finished.

"OpenStreetMap.org User's Diaries": Kanata Lakes updates

Thu, 10 May 2012 14:35:12 +0000

It has been raining those days I wasn't motivated to take new trails around but I managed to record two loops since last week and I updated them today. They're located west of the Beaver Pond Park. The two entrances are just across the parking area (that I also added to the map) on Goulboum Forced Rd. There are more trails there but I'm taking the larger loops and not-so-wet paths. I'm not sure if it will be convenient map every side trail in that area, but I think I will. Unfortunately, those trails are marked to be vanished as development in the area advances against the woods. That area is marked as for development and they will be gone in few years as what happened with the woods north of the Beaver Pond. I roughly contoured the area to mark the clear cut and update the map. If the development is inevitable, at least my hope is it should take 20 years or so.

Habrahabr OpenStreetMap (RU): Отображаем карты OpenStreetMap на iPhone 4 с учётом сетчаточного дисплея при помощи Leaflet

Thu, 10 May 2012 13:23:26 +0000

Всякий, кому до сегодняшнего дня доводилось запускать полноэкранный пример работы движка Leaflet на новейших мобильниках iPhone 4, неизменно получал перед собою вот какую карту OpenStreetMap в новоайфоновском разрешении 640×960:

Как видите, векторный гипертекст (подпись под картою) выглядит существенно лучше по качеству, чем растровый текст (надписи на карте) и чем контуры дорог на карте. Это потому, что растровые картинки на сетчаточном дисплее по умолчанию состоят из квадратов 2×2 реальных (физических) пикселов — стало быть, растровый текст получается угловатым, контуры дорог получаются ступенчатыми, и так далее.

Сегодня это положение дел изменилось к лучшему.

ШТОСМ: В конкурентной борьбе проиграли, можно расслабиться

Thu, 10 May 2012 08:30:45 +0000

Danidin9 стахановскими темпами картирует северные районы Петербурга и сетует, что в том же НЯК гораздо больше участников уделяют внимание POI:

Возьмём, к примеру, [один из домов]. В реальности (сегодняшние данные) там 12 объектов разного рода: несколько магазинов, жилкомсервис, почта и т. д. + 2 вакантных места. На НЯК из них отмечено 9, на OSM — 0 (ноль). При этом те 9 poi в НЯК были созданы четырьмя разными людьми. Т. е. это не дело рук энтузиаста-одиночки, а реально труд сообщества, в котором даже если кто-то выйдет из игры, это не помешает поддерживать данные в относительно актуальном виде. И это далеко не единичный случай. Куда не сунусь — везде примерно одно и то же. На Васильевском острове до сих пор полно кривых домов, нарисованных в 2009 году по яху, и до последнего времени никто не брался их улучшать. До сих пор во множестве кварталов не отмечены внутренние проезды, не говоря уже о воротах, шлагбаумах, «лежачих полицейских» и т. д. Небольшой город Каменногорск, если бы я за него не взялся пару недель назад, так и бы представлял собой пустыню с редкими poi, отстоящими от реального местоположения на сотни метров. И даже теперь, я ведь не могу по спутнику отмечать номера домов и уточнять poi! Нужен местный маппер. В НЯК такой есть, в OSM — нет.

В OpenStreetMap всё больше ощущается нехватка полевых мапперов. По самым оптимистичным подсчётам, для поддержания карты в нормальном состоянии нужен 1 энтузиаст «в поле» на городской район с населением тысяч 30-40 (пешком), 10-20 (в центре/у метро) или 50-100 (если есть велосипед). На Санкт-Петербург в таком случае нужно 100-150 человек, на Москву — 200-300. Это в 10-20 раз больше, чем есть сейчас.

Далее он предлагает решать эту проблему упрощением интерфейсов сбора и ввода данных, необходимость которого понятна всем, кроме тех, кто реально может что-то сделать: программистов. И незримо на периферии продолжает висеть вопрос: так ли нам нужно снижать порог входа? Попрут, ведь, многочисленные школьники с синдромом дефицита внимания, поломают все ваши любимые мультиполигоны.

Кстати. Один из мапперов-затворников, наконец, высказался (также в бложеке) и вместо диалога начал жаловаться, что он тут работает, а его труды никто не ценит, и карта отстаёт даже от Эстонии, и что же вы сидите без дела — рисуйте, привлекайте новичков, развивайте картографию, будьте сообществом, вместо того, чтобы набрасываться на трудолюбивых участников. Всё как обычно.

Тем временем, робота всё пилят, дампов давно не видели, а на улице жарко. Осму треки собирай.

"OpenStreetMap.org User's Diaries": Gesamtes Gelände als "Pub" taggen

Wed, 09 May 2012 12:08:58 +0000

Nach dem freundlichen Wink mit dem Zaunpfahl hab ich mich nochmal mit meinem Biergarten- und Gaststättenproblem auseinandergesetzt. Manchmal ist es ja auch einfach besser, die Sachen kurz ruhen zu lassen und dann später nochmal frisch an die Sache heranzugehen. Mein Fehler lag darin, das ich das gesamte Gelände, das zu der Gaststätte gehört (also auch die Aussenfläche) als "Pub" getaggt habe. Hat in dem Moment für mich Sinn gemacht, da es sich dabei um eine Parzelle in einer Kleingartenkolonie handelt und ich eben dieses gesamte Gelände davon abheben wollte. Letztlich bleibt es aber eine Parzelle dieser Kleingartenkolonie, auf der bloß eine Gaststätte befindlich ist. Somit bleibt das Gelände als Kleingarten bestehen und ich stell da nur die Gaststätte und den Spielplatz drauf. Beides kann man flächig etwas größer machen, aber ob ich das jetzt besser oder schlechter als nur das Symbol finde weiß ich gerade nicht. Gibts dazu eigentlich eine Standardvorgehensweise?

Mappa Mercia (UK Midlands): Surveillance gone mad?

noreply@blogger.com (Mappa Mercia) — Wed, 09 May 2012 10:54:00 +0000

Can anyone beat this for density of surveillance cameras? I know we live in a security-conscious world but I think this is a bit excessive. Spotted on Broad Street in Birmingham between the Hyatt Hotel and Symphony Hall. Or maybe there is a technical reason for this configuration? They seem to me, as a non-expert, on cursory examination to be capable of horizontal 360 degree rotation.

Has anyone noticed the growth of ANPR (Automatic Number Plate Recognition) cameras at the exit of many motorway service stations?

Whilst on the subject of ANPR cameras, there was a major national news story last year about a blanket installation of ANPR cameras in the mainly moslem areas of Birmingham, financed by a counter-terrorism budget and erected without local consultation. After a short and controversial political battle they were removed.

Now they seem to be sprouting up on many trunk roads and major routes into and out of Birmingham, so that the entire city is covered. Has anyone else noticed them? Are they sprouting up in other cities? I think there has long been a ring of such cameras around the City of London ( the financial district)

This post I guess has been a long time coming, basically hit it’s zenith and then subsided. About a month ago I had serious doubts within the PhD, around whether I was ‘good enough’ to complete. The majority of doubt focused around completing what I had perceived to be an easy task of implementing a ‘simple’ algorithm. This turned into three weeks of nothing. Breakthrough occured on what was supposedly a three day break in Marseille – before a 12 day conference schedule in Avignon (AGILE) and Amsterdam (WhereCampEU).

It would be fair to say I’d hit the lowest point of the PhD then. It was a sequential thought process, if I can’t do this simple thing, how am I prepared for the harder things later. Doubt set in, and the analysis was concluded in that I should quit. Then the break through came and all was good, confidence restored. I then read ‘The Valley Of Shit‘ a blog about going through the same thing; “Valleys lead to somewhere else - if you can but walk for long enough. Unfortunately the Valley of Shit can feel endless because you are surrounded by towering walls of brown stuff which block your view of the beautiful landscape beyond.”

Anyhow, I feel out of the valley now. All is good.
