admin boundaries: TIGER vs OSM...

Wow. There are some interesting challenges in trying to figure this out.

I have figured some things out about how to find TIGER info in OSM. I can do things like look for "tiger:reviewed"="no".

I have downloaded a bunch of the TIGER data. I am going from the directories under ftp://ftp2.census.gov/geo/tiger/TIGER2015/. One challenge I am having is finding the longitude and latitude data. I know it is there somewhere. Is it in the files under EGDES? No. Under ROADS or ADDR? No. Only 40 or so more to check.... But I am looking at only the dbf files in those zipped files, using the dbf2mysql utility for Ubuntu. Is the lat/long data only in SHP files? That would be obnoxious.

But the TIGER data does have TLID fields. So this should help me. Because OSM features have a "tiger:tlid"=num value. So, I should be able to pick a TLID from the TIGER data and see it in OSM, or see and id on OSM and find it in the TIGER data, right? Maybe not so much.

I have over 12,000,000 edges. I have all of OSM. Can I find one place where an id appears in both? No. How should I search? Randomly? I have done a bunch of random checks and so far I hit nothing. Which kinds of id values appear in both? Does OSM only include polygon objects? Or any of the other 20 or so types in TIGER? There are so many ways to slice this. I am sure when I figure this out, it will be sooooooo obvious..... :-)

We will see.

CheckAutopista2 is here

If you just want to try it out right away here it is: http://k1wiosm.github.io/checkautopista/

Interstate 15 in California on CheckAutopista

I have been working on this for months now. The new version of CheckAutopista is faster, easier to use on mobile devices and has been completely redesigned from the ground up.

What is CheckAutopista?

CheckAutopista is a quality assurance tool for motorways. This tool allows you to select a motorway in OSM (if it is tagged in a relation with type=route and route=road) and check a lot of features in it.

Car navigation is clearly one of the most popular use cases of OpenStreetMap data. Assuring that data is of high quality is a hard task, and even harder if we don't have any tools that help us detect missing, incorrect or old data. That is how visualization tools can help us.

CheckAutopista allows you to visualize a motorway in a simple interface using colors to detect missing information such as maxspeed, lanes, destination, exit_to, name, ref and to visualize exits, toll booths, service and rest areas.

What is new on CheckAutopista2 ?

  • CheckAutopista now comes with a custom designed background map which emphasizes motorways.

  • CheckAutopista has been totally remade externally trying to make it more beautiful and easier to use.

  • CheckAutopista can be used easily on small mobile devices. You can change the size of the circles on the settings.

  • CheckAutopista now supports destination:ref and destination:int_ref tags on the exit panels.

  • I am trying to contribute to the usage of destination tags instead of exit_to tags, so CheckAutopista now uses the green color only for destination and yellow for exit_to.

  • CheckAutopista is now much more efficient on the Overpass API requests making it much faster.

  • CheckAutopista has also been totally remade internally to make it faster and improve on the readability of the code.

Examples

Here are some examples of some motorways of the world on CheckAutopista:

That is all. I hope you like it. If you have any suggestions please leave them in the comments below and if you would like to see the code, report any bug, contribute or fork it: https://github.com/k1wiosm/checkautopista2

Когда осмеру делать нечего...

...он садится на велосипед, достаёт блокнотик/смартфон и мапит свой город поквартально. Результаты сей деятельности в исполнении автора видны из приведённой ниже схемы:

Конечно, в "красных" кварталах на севере не только квартиры добавлены: если бы я занимался только этим, то было бы слишком просто. Там и все дороги нарисованы, и дома в 3D, и лежачие полицейские, и детские площадки, и много чего ещё. Тут ведь как: начнёшь с одного, а там вылезет ещё что-нибудь, а потом ещё и ещё. Расположение подъездов малоинформативно, если дом нарисован криво, а если выправлять его, придётся и дороги двигать, и заборы, и т.д. Но именно по ситуации с addr:flats результаты работы нескольких месяцев выглядят максимально наглядно.

В общем, за 4 тёплых сезона (немного - в 2011, 2012, и побольше - летом 2013, и в июле-августе нынешнего) в OSM были внесены номера квартир в более чем 10 тысячах подъездов, в которых проживает, по общим прикидкам, миллион человек. Не обошлось конечно и без интерполяции, там где она была уместна. Тем не менее, считаю полученные данные достаточно валидными для подсчёта численности населения в том или ином квартале (исключая, пожалуй, лишь общежития и подобные им здания - к ним нужен отдельный подход).

Два года назад я первый раз подбил статистику по использованию тега addr:flats. Что же изменилось с тех пор? Общее количество употреблений тега возросло в три раза, с 15 до 47 тысяч. При этом доля России не только не уменьшилась, но и выросла, превысив 72%; а вместе с ближним зарубежьем достигла 90%. Рейтинг же по городам, по состоянию на нынешний день, выглядит так (топ-22):

  1. Санкт-Петербург 12917
  2. Москва 4994
  3. Витебск (Беларусь) 3876
  4. Владимир 1342
  5. Краснодар 1273
  6. Россошь (Воронежская область) 1209
  7. Луцк (Украина) 1206
  8. Киев (Украина) 995
  9. Жуковский (Московская область) 886
  10. Новосибирск 806
  11. Томск 776
  12. Выборг (Ленинградская область) 745
  13. Троицк (Челябинская область) 729
  14. Коломна (Московская область) 694
  15. Архангельск 671
  16. Ульяновск 538
  17. Екатеринбург 421
  18. Хельсинки (Финляндия) 389
  19. Авдеевка (Украина) 384
  20. Калуга 332
  21. Каменск-Уральский (Свердловская область) 328
  22. Шлиссельбург (Ленинградская область) 300

Вид рейтинга очевидно странный, и наличие в нём целого ряда райцентров говорит о том, что даже в России тег addr:flats используется лишь отдельными энтузиастами, рисующими карту "в поле". Можно даже сказать, что на постсоветском пространстве он является одним из индикаторов происхождения данных (а также и их качества). Ведь вряд ли где-то есть базы в открытом доступе, где содержатся геопривязанные данные по нумерации квартир.

Que tal jogar "Pac-Man" pelas ruas da sua cidade? - Conheça o BucketMan - Coloring your city

Fiz a tradução para Pt-Br sobre o wiki do aplicativo. Confira:

"BucketMan - coloring your city" ("BucketMan - colorindo sua cidade") é um jogo para dispositivos móveis que é similar ao Pac-Man mas o cenário é as ruas do mundo real. Atualmente ele só foi elaborado para dispositivos com Android. Mas em breve você também poderá jogar em seu IOS. O jogo está em seu estágio beta e pode ser baixado na playstore. Ou também pelo site oficial do game. Você pode ver o video de divulgação do game em português (Pt-Br) no youtube.

O Jogo:

No jogo você controla o BucketMan para colher água e tintas de modo a evitar que os VIA (Veículos de Inteligência Artificial), em inglês AIV's, dirijam pela cidade com um unico objetivo: dirigir o máximo possível, congestionando a cidade. Você pode pular sobre os AIV´s e recolher tintas para pintá-los, deixando-nos inofensivos. Você pode desbloquear as supertintas para ficar o "hulk" e daí quem atropela os carros é você. Dependendo da cor, você tem a recompensa. Durante o jogo você pode mudar a água e as tintas para melhorar as habilidades (velocidade, tempo de pulo, ...) e as características (tempo de vida, entre outros).

O tempo não pára e você precisa coletar água para poder passar de fase, com a água você ganha tempo, e matando os AIV's também.

Há dois principais modos de jogo: Missões e sobrevivências. Nas missões você tem que fazer as tarefas, como pular sobre 8 AIV's, pintar certos AIV's de determinadas cores, matar um certo número de AIV's de uma específica cor, ...

No mapa de sobrevivência você simplesmente tem que... sobreviver. Aqui você pode coletar águas e tintas para deixar seu BucketMan melhor. Existe também um ranking mundia via Google Play Game Services para mapas salvos, onde constam as pontuações de cada mapa. Além dos mapas salvos você pode também jogar os mapas online do local onde você está (desde que haja conexão com a internet e GPS).

Os mapas online são enviados pelos usuários de todo o mundo. Cada mapa online tem seu próprio ranking que permite uma batalha pelo comando de seu bairro.

Missbrauch des name tags

Zunehmend finde ich Objekte bei OSM die einen ziemlich obskuren bis kaputten name tragen. So z.b. name=Kuhtunnel oder auch name=Neuer Radweg oder sogar nur ein name=Radweg

Das name tag sollte den namen tragen und nicht eine ausführliche Beschreiben des Objektes oder dessen Nutzung. Das das ein Radweg ist wird sich durch eine Sammlung von highway tags erklären dazu bedarf es keinerlei Beschreibung.

Das ganze fällt immer dann auf wenn wirklich jeder name gerendert wird und dann mit einem durch zufälliges label placement nicht mehr der Name der Bundesstraße sondern dort "Kuhtunnel" steht.

Mal ganz davon abgesehen das dieserlei Namen dann jeglichen Index aufblähen.

Wer sucht schon nach "Radweg".

Ich bin durchaus dafür zwecks Mapper kommunikation strittige Objekte mehr zu beschreiben oder im Freitext zu attributieren. Das sollte dann aber in einem note stehen und nicht im name

Пешеходный роутинг — новый вызов для OpenStreetMap




Вокруг пешеходной навигации и сообщества открытых карт сложилась интересная ситуация. Пешеходные картографические данные OSM уже уникальны. Ни один поставщик в мире сейчас не способен предоставить такого количества тротуаров, переходов и троп, которое есть у OpenStreetMap. Но вместе с тем до удобного промышленного использования этих данных ещё очень далеко. В результате OSM и его сообществу снова придется пройти испытание на прочность.

Trvelling and explore places connented with World War II

World War II was vary cruel time in national history. This time show what people can do to be on the high of the authority. This time show us how much cruelty people have inside. This time should be warning for new generation to do all what we can to not allow to happen such a big conflicts, and especially racial conflict. Nowadays people are more tolerant for any kind differences. People want to integrate, we want to integrate and piece to live comfortable. Our mind should feel comfortable. It's very important to educate new generation, and not only young people, but also this who lived a lie, who couldn't find out what really happened. we should spread knowledge about history of this time. I am going to plane my route in the footsteps of the World War II to create program which will be attractive for people and simultaneously will be educate. If someone is willing to help me or could give me some tips please write comment.
I'll be glad.

Expanding the OSM Community

One common theme weaved into the State of the Map US conference was the difficulty of community onboarding...once people are finally drawn into OpenStreetMap, how can we retain them and help them feel like a part of the community? I think we should have some sort of OSM Ambassador program. A welcoming committee, or mentoring program, that reaches out to greet new users as they join the community and serve as a contact point for questions about OSM, correct tagging, using the data, or just why this community is so great. This group can also be the connection from individual mappers to local OSM chapters, Maptimes, and other organizations.

The program should be somewhat local, focused on the country, province, or even city to provide a “local” touch to the communication--not just a generic response. The ambassador/mentor/welcomer doesn’t necessarily have to live there, but it would be great for them to have some knowledge of the location to provide advice tailored towards that region. This initial contact would perhaps help the new mapper realize they aren’t the only person in a TIGER desert of nodes. It would also give them a direct contact point if they don’t want to approach the mountain of mailing lists or try their hand at IRC and other help mediums.

A similar mechanism has likely been informally happening already by many of us in the community. I have personally sent messages to people as I’ve randomly seen a new editor show up in the history, usually when they are in my area. Minh Nguyễn, had a great talk at the SOTM US, where he touched on how he has also reached out to new mappers in the bigger picture of inspiring local mappers. It makes sense that we already do this, because we truly care about the OSM community. But we should organize our efforts so that we can ensure all of the areas are covered.

This project is, I think, the biggest step forward for springboarding an ambassador program. We should look to organize this worldwide and rally around welcoming people into our community to provide a group of fellowship for mapping and open data!

admin boundaries: school districts in CA, US

My continuing effort to learn, before I start adding a bunch of data, the proper way to get relations for the school districts in CA into OSM is making me aware of some interesting issues.

Question: Is there a tool that takes a relation id (or presumably a node or way id) that allows you to add or edit a key-value setting? In the relational db, this would be a simple update statement. Is OSM, you download the entire relation, add the value and upload all (I think) the data. This to change or add one key-value pair. It seems a command-line tool for doing this would be an obviously useful thing.

I recently spoke with someone at the Santa Clara County Registrar and found out how they use GIS data. Or rather, how they do not use it. They have to run elections, such as school board elections, and also state or country races. The state gives them district boundary information as TIGER data. The county gives them something else. And school districts provide them, basically, with textual lists, like narrative maps. Apparently they list streets and which side, or both sides, in a completely non-standard ways. So, the Registrar has to manually sync this up with their data. Could these government entities be using OSM data? I think they could....

That being said, TIGER says this:

 STATEFP: 06
 ELSDLEA: 38460
 GEOID: 0638460
 NAME: Sunnyvale Elementary School District
 ELLSAD: 00
 LOGRADE: KG
 HIGRADE: 08
 MTFCC: G5400
 SDTYP: 
 FUNCSTAT: E
 ALAND: 35549740
 AWATER: 9341
 INTPTLAT: +37.3897355
 INTPTLON: -122.0247588

Obviously there is TIGER meta-data in the OSM map. But locating the ways defined via TIGER for "GEOID" = "0638460"? I am still trying to figure out how this works. Maybe the Overpass syntax for this will one day be obvious. (sigh). I hope so. For now, I can re-use and extend queries that people are handing me, but I do not grok enough to actually write any query that works as I expect.

It would be good to be able to go to government entities and say: "If you verify your geographic boundaries in OSM, you will be able to use this set of lines defined by this tag and track/verify/ignore changes to them so that your internal systems can use OSM." I can't say that yet. We will see.

From JOSM search & replace to processing Openstreetmap with your favorite text edition tools

There you are, in some Openstreemap editor, correcting the same typo for the 16th time, cursing contributors who neglect correct capitalization and thinking about how tedious this necessary data gardening is. While JOSM is endowed with unfathomable depths of cartographic potentiality, you long for a way to simply whip out your favourite text editor and apply its familiar power to the pedestrian problem of repeatedly editing text. Or the problem requires editing multiple mutually dependent tags and some XML-aware logic is therefore required – all the same: you just want to perform Openstreetmap editing as text processing.

Daily MAPS.ME data updates

If you are not yet using MAPS.ME, you are missing out :) The most frequent complaint from the mappers was that official maps in that application get updated only once a month, along with new releases. I usually map stuff the day before I'm going out, so this update cycle does not suit me. And since I work for them now, I can fix this.

Since this month, there are daily updated map files for MAPS.ME. To install downloaded files on Android, find MapsWithMe directory on your device (you can check "Settings → Map storage" in the app), and put new files there. You should delete old maps and directories with same names (the latter is to clear caches). And probably restart the app. On iPhone and iPad, just use iTunes: find and open MAPS.ME application, delete old maps, upload new.

Maps are published every day at around 5am UTC. Mwm files are maps, routing files are needed for car routing (pedestrian routing doesn't need them). In a couple of days a new version would be released, and it will be required for daily maps to function.

These files are not official. The application may behave strangely (there will be notifications about outdated maps), data may be broken (it's OSM, it is always broken), and your application may crash. If you encounter anything strange, you can clean the MapsWithMe directory and/or move the app from SD to the device memory, which must fix most bugs. Daily maps are my initiative, and MAPS.ME company is in no way responsible for these. Of course, I'm ready to answer any questions.

Geomob London

September 30th #geomob details

Fellow geomobsters,

I hope the summer is treating you all well. 

Our next event will take place on the evening of the 30th of September. As always we’ll kick off at 18:30, and likewise we shall stick to our time honored formula: 5-6 speakers from across the gamut of those doing interesting things in London in geo.

We’ll be back at UCL in the Pearson Lecture Theatre, there is a map on the Lanyrd page for the event (please sign up so we can get a sense of the numbers). I’d like to explicitly thank longtime friend of #geomob Muki Hakley Professor of Geographical Information Science at UCL for once again making their facilities available to us. It is only through such generosity that #geomob is possible. Muki you are ace!

We are still finalizing some of the speaking slots, but at this point I can announce three of our speakers for the evening:

Following the talks we will, as always, vote for the SplashMaps best speaker and then head to a nearby pub where the drinks will be paid for by our sponsors. Please check our their services and let the world know how great they are.

As one example of many of how great our sponsors are, and as an added incentive to join us on the 30th, our new sponsor Esri UK will be raffling off a beautiful book on map design to all attendees in what we hope to make a new #geomob tradition.

One final point, for those who can’t wait until the 30th of September to get their geo fix, keep in mind that GeoHackDay is happening on the 5th of September. 

See you on the 30th of September at UCL,

Ed

post-vacations map editing

Amorgos view

Greek islands are a great place for summer vacations. This year I visited Amorgos, part of the Cyclades island group, and had a short visit at Pano Koufonisi.

Being in a new place means you need some kind of map to guide you through the endless number of beaches, paths and villages. I've been using OpenStreetMap as a map source for a long time and occasionally I contribute back. OpenStreetMap is a collaborative project to create a free editable map of the world. Many people call it the Wikipedia of maps, and it is in some extent. In contrary with all the major industry map services, which utilize free labor from volunteer contributors and give nothing back, OpenStreetMap data are freely distributed to be used by anyone for any purpose.

You can find many places where OpenStreetMap has more rich data than other sources or read stories on how targeted mapping on specific incidents saved thousand of lives. But there are also many places where it lacks reliable data. Amorgos (and unfortunately many other Greek islands) is one of these cases.

During my vacations there I used the only equipment available (my phone) to keep notes that would help me later to enrich OpenStreetMap. I extensivly use Osmand as my main navigation tool so this was my first option of keeping notes. You can either add favorites to mark any POIs or use the notes plugin to take photos or record audio notes. Osmand has also an editing plugin that can help you edit data on the fly, but I prefer to do this later. If you are searching for a more simple app OSMtracker is a better choice, for tracking routes and keeping notes. If you don't have a smartphone during your vacations you can just use paper and pen. Field Papers will help you print the map area you are interested in and you can keep notes with a pen.

Getting back home I had many notes and plenty of work to do. OpenStretMap has a great in-browser editor and the Map Features (really long) wiki page can guide you through the supported map elements. I added/changed around 90 map elements (beaches, paths, roads, buildings, etc) and it took me about an hour. Less than a day later the changes were rendered to the live website and I could feel proud about my contributions :)

So did you enjoyed your vacations? Now start contributing to OpenStreetMap so more people can enjoy the travel to all the places you visited. Happy mapping :)

Mapeando mais locais históricos em grupo

Registrando rapidamente a atividade, nesta quinta, dia 20/08/2015, visitamos o bairro Barreiro Cabral nas proximidades de onde ficava o bairro Freguesia Velha. Lá se encontram grandes riquezas visuais, naturais e históricas.

Primeiro visitamos o cemitério que foi transferido da Freguesia Velha para construção da fábrica de cimento por volta da década de 70 e a igreja erguida ao seu lado.

Depois fomos um pouco mais na frente até uma mina de ouro abandonada, dos tempos do ciclo do ouro na região, onde existe ao lado uma famosa figueira gigante e logo abaixo, no Rio das Almas, um Encanados, construção de pedra para exploração de ouro apresentando pedras que foram cavadas por intervenção humana.

How many HOT contributors never complete their first task?

I only recently realised that HOT contributors need to mark at least one task as "done" to be listed as project contributor in the tasking manager. This made me wonder: how many people start contributing to a HOT project but never finish their first task? What proportion of all HOT edits are contributed in this manner?

Summary: about half of all HOT contributors never complete their first task on a project, although they do contribute to the map. These "partial" contributions account for 10-20% of all HOT edits.

Here's a timeline of the number of monthly HOT contributors, compared with the number of those who completed at least one task:

HOT contributors with completed tasks

And here the corresponding timeline of the number of edits contributed by both groups of people:

HOT contributions and completed tasks

Expressed as percentages:

Share of completed work

We don’t know why these contributors never completed the task, we can speculate but really we would need to ask them. Some may have forgotten to close it after they were done, some may not have had the confidence to mark it as "complete" and wanted someone else to have a second look, some may have gotten distracted, or lost motivation, etc.

It's also worth bearing in mind that we can always expect some proportion of tasks to be abandoned early: not everyone is interested in contributing to HOT in the long term. Many people are likely simply curious and try it out for a bit. Many may have come across HOT because a friend sent them a link, or because it was in the news, and we can't expect all of them to stick around.

However we should also be mindful of these early experiences. On one hand we can improve our understanding of what makes people stop early. On the other hand we should also consider the impact these contributions have on our map, and on validation and QA efforts. Where should we send absolute newcomers the next time we're in the news?


Some background info on the analysis...

I’m identifying HOT contributions in the OSM edit history as follows:

  • The contribution needs to fall within the geographic boundaries of a HOT project
  • The contribution needs to happen within the activity period of the HOT project
  • And then...
    • EITHER the user is a listed project contributor (they marked at least one task as done),
    • OR the changeset is tagged with a valid HOT project ID (the contributor never marked a task as done, but likely did start a task in the tasking manager before contributing edits.)

There are some caveats with this data:

  • In this analysis, one completed task by a contributor is enough to regard all their contributions to the same project to be marked as "done". The simple heuristics above do not allow me to distinguish task completion states for all individual changesets of a contributor to a project.
  • We can't distinguish contributors who never mark a task as "done" from validators, or expert contributors who manually tag changesets with a project ID. We don’t have the data to distinguish these cases, e.g. there is no published list of validators to compare against.
  • We can only reliably track this from Aug 2014 when iD started carrying over project-specific changeset tags from the tasking manager. We won't be able to identify "unsubmitted" contributions before then.

[Из песочницы] Установка и настройка генерации тайлов на основе OSM данных под Windows


Дисклеймер


Недавно по работе возникла задача генерации тайлов на основе OSM данных. Поискал, прочитал несколько статей, но везде фигурировали *nix-системы, а у меня был в наличии сервер под управлением Windows. В конце-концов, более-менее внятный туториал нашёлся, но он слегка устарел и не везде подробен, посему пришлось повозиться. После удачного завершения подумал, что мой опыт будет полезен.

Кого заинтересовал, прошу под кат.

A complete map

I saved my 10,000th changeset yesterday, as part of a months-long surveying and mapping spree in San José, California, where I currently live.

I never intended to map the Bay Area. Instead, I typically spend my free time helping to map my hometown of Cincinnati and tame TIGER deserts elsewhere in Ohio from the comfort of my (armless) chair. I always assumed that the middle of Silicon Valley would be full of tech enthusiasts who occupy their time by micromapping every last bench and bush. The map sure looked complete, with lots of highway=primarys and highway=secondarys, landuse areas covering every square inch, and plenty of rail and bike infrastructure.

But then, in April, I zoomed in. I had recently joined Mapbox to work on iOS map software, and the Show My Location function went right to my unmapped doorstep. Around me was an endless parade of outdated street configurations, missing landmarks, test edits, proposed BART stations tagged as the real thing, and GNIS-imported hospitals that had been closed for years. Most of the map hadn’t been touched in six years. In terms of POIs like shops and restaurants, central San José in 2015 was as blank as Cincinnati was in 2008. (San José is the country’s tenth-largest city, with a population 3½ times that of Cincinnati.)

before
Zoom in all the way to the spot marked San José, and this is what you would’ve found earlier this year.

As I added in pent-up local knowledge, I couldn’t help but notice some unfortunate tagging practices. The Bay Area is (ahem) liberal in its use of highway=primary and highway=secondary. It wasn’t difficult to find quiet residential roads with speed bumps, Child at Play signs, or unsignalized crosswalks being tagged as secondary, the same tag often used for heavily-used roads in other cities or 55 mph state highways in rural areas.

Most of the giant landuse areas that blanket the city need to be redrawn. Many landuse=residential areas conflate distinct neighborhoods or include tree-lined business districts (which look like residential areas from the air). Meanwhile, many industrial areas are being converted into residential areas due to a local housing boom. As much as possible, I’m replacing these generic landuse areas with more specific ones that correspond to individually named subdivisions, office parks, and retail complexes.

landuse
A typical landuse=residential area in San José spans multiple highway=primary roads. Either these aren’t really primary roads or this isn’t really one coherent residential area.

I suspect that the highway classifications and generic landuse areas, combined with decent rail data, made the map look a lot more complete than it really was. To a newcomer, the total absence of restaurants, buildings, and non-armchair-mappable information might’ve looked like a limitation of the project rather than a blank slate waiting to be edited. And again, there should be no shortage of visitors from San José, because this is Silicon Valley, where people talk about things like OSM. I’m sure the original mappers were doing their best at the time; unfortunately, six years ago, none of us knew as much about mapping ago as we do now.

San José is looking a lot better after an intense few months of surveying. There are plenty of POIs downtown – too many to fit onto the map at z19, in fact – as well as invisible attributes like speed, weight, height, and turn restrictions. I’m having particular fun mapping the many ethnic enclaves around town, which are very poorly represented on commercial map services.

caribees
This popular ethnic strip mall is now fully mapped in OSM (seen here in iD at z20). Apple and Google make a mess of things.

dgsmetoc
The San José place=city POI incorrectly sat 12 blocks away from where it should’ve been, at the site of this church, which incidentally is missing from Apple, Google, and HERE.

dgsmetoc name
Meanwhile, OSM now includes that church, as well as its full Amharic Ethiopian name. (Deciphering the Amharic signage was a challenge in itself.)

Still, that’s only one city. We’ve always known TIGER deserts are a problem, but are other cities similarly languishing after an initial burst of detail, flying under the radar because we all think they’re being taken care of? Maybe we can prevent that from happening in the future by making the map look only as complete as it really is.

Creating New Volunteers: OpenStreetMap Training for Students

Under their Child Rights Governance(CRG) project in Dhaka Save the Children International has taken initiative to share local knowledge in open platform and involving community in the knowledge sharing and using process through available technologies. Save the children has decided to teach OSM knowledge to community youth group including adolescents sothat they can share the updates of the surrounding features in Slum areas where they are living. The knowledge will be then used through community health service apps during the needs of people in slum. Keeping the sustainability in mind Save the Children has taken decision to provide the training same time to more 100 university students along with slum youth groups. This capacity of the student community will contribute not only in CRG project areas but also in the open map data base Bangladesh. Ahasanul Hoque(@ahasan4u), GIS specialist and OSM trainer is conducting the trainings starting from 24th August 2015. All training will be held at Save the Children Office, Dhaka [House CWN (A) 35, Road 43, Gulshan 2, Dhaka 1212, Bangladesh] and the mapping parties in slum areas will be held in Mirpur Sector 13 area of Dhaka city starting from October 3rd, 2015. #hotosm #missingmapsproject #osmbd #osm blogs

Hacking on mobile apps with the London crowd

The OpenStreetMap London hack weekend also saw Jo Walsh working on the first stage of a building details editor for Android.

Jo, who goes by the OSM user name zool, has written up her experience of working with Android:

I worked on a mobile app which I was pleased to get into a basically working state. It is called osmbi3, which stands for OpenStreetMap Building Information and/or Zombies. The aim was to geolocate the user and find nearby buildings using an Overpass query. This could then be linked to building management information or form the basis for some location-based game.

OSM retail survey: Conclusions-2

This picks up from previous posts to consider more specifically what tools might help contributors.

The examples are rudimentary – stuff I've assembled for my own use, rather than robust tools for the wider community. If they have any value I hope it will be as prototypes for something more polished.

Missing data


There are about 385,000 retail properties in England that are missing from OSM, and the obvious way to help contributors is to point out where they are.

To help achieve the most rapid improvement across the whole country I have tried to find dense retail concentrations that haven't been thoroughly mapped yet.



These are the biggest concentrations of unmapped retail property in England and Wales: about 1,000 of them, each with an average of 100 missing retail outlets across an area of under 2 sq. km.

I've used a mix of Food Hygiene Data, Non-Domestic Rates, population data, and various other statistics to identify concentrations of retail outlets at a local level. I've done this for England and Wales. The same basic technique should work in Scotland because similar data is available, but the structure of the census geography, and data on non-domestic rates for Scotland is quite different, so the process needs tweaking, and I haven't got round to that yet.

My formula for estimating the number of retail premises at a local level can probably be improved, but it will never be perfect. At this stage I don't think it is good enough to reliably identify areas that are almost complete, because that needs more precision. But I think it is good enough to flag up areas that are far from complete. Contributors who are looking for significant concentrations of missing retail outlets should be able to do a quick check on the area. If it still looks empty on the map, they can head there with a reasonable expectation of adding enough new retail outlets to make the trip worthwhile.

Feedback based on local knowledge would be welcome, to help refine this a bit more.

Helping contributors to find nearby concentrations of missing retail outlets is one way to quickly increase the overall volume of data. A different starting point is to assume that thorough retail coverage in some areas has a higher value to data users than adding missing shops elsewhere. On that basis we may want to encourage contributors to concentrate first on mapping areas which we think have the highest potential value.




This example picks out a limited number of smaller towns and cities where OSM data might have high value (e.g. to students or visitors).

Areas coloured:
  • blue already contain more than 75% of my estimated number of retail outlets
  • green contain 50-75% of my estimated number of retail outlets
  • orange contain 25-50% of my estimated number of retail outlets
  • red contain less than 25% of my estimated number of retail outlets 

Each area is intended to cover a manageable size: one where a few contributors should quickly be able to bring retail content up to an impressive level. Larger cities are excluded on the basis that they justify a more systematic approach. My list is  bit arbitrary – it is intended to cover a mix of different towns of roughly similar size, distributed across the country. Are these really the areas where OSM retail data is likely to have most value? I doubt it, but that might be a useful discussion point in its own right. For each suggestion of a settlement that should be added, please feel free to suggest one that should be removed.

I can only assess how useful these estimates might be in areas that I know fairly well. Feedback on any unexpected results would be useful: to better understand where the technique can be improved.

Feedback to contributors


All contributors deserve to see the results of their work. But not all retail information is rendered on the standard map. And in my view it never can (and shouldn't) be. So to encourage contributors I would like to see a decent alternative to the standard map which shows more complete retail information. When I want to check specific content of the database I use either a data extract, Overpass, or the “Map Data” overlay on the standard map view. I'm happy to do this, but for many contributors (and particularly for novices) none of these techniques are particularly user-friendly. I suspect this is beyond my own technical capabilities, but there are examples (based on various data extracts) that illustrate the kind of thing that can be done.


Data collection


When mapping retail areas there will normally be some shops already recorded in OSM, which need checking. Alongside other existing features such as road junctions, these also provide reference points for adding new data. When surveying retail premises, it's handy to have a crib sheet to hand, on which to collect notes of any changes, which shows the current state of the data. This needs to show every relevant feature in the database, including some which won't be rendered on the standard map.

Below is an example generated (automagically, with some rather clunky SQL) from OSM data for Winchester High Street (the pedestrian part). It starts at the western (top) end.



I've set this up to collect any shops, amenities and offices within 25 metres of the highway centre line, and display them in order. This simplistic approach only exhibits the most basic information, and includes more features than I would really want: including shops beyond each end of the central line, up side streets, and occasionally from a nearby street running parallel. But it's easy enough to cross out any unnecessary entries. To allow for some additions there's an additional spacer inserted every 20 metres (roughly twice the width of a conventional shop front). I find sheets like this speed up the data collection process and make it easier to add notes.

Consistency checks


I hope I've made a clear case that across most of the UK adding missing retail data is a higher priority than cleaning up tagging inconsistencies. However, this isn't true everywhere, and pointers to inconsistencies could help contributors to clean local data.

Some basic consistency checks are easily carried on Overpass:



But this isn't ideal for finding all quirky data within a local area, and finding more complex inconsistencies sometimes involves extensive processing that isn't really practical interactively. Overpass isn't the ideal solution here, but it is possible to do more crunching on a data extract. Here are some examples. Unlike Overpass, anything here that is fixed won't be quickly updated in the overlay (some of these quirks are already fixed, which could get annoying). Note that, for the sake of simplicity, this overlay only contains some of the features in the UK that exhibit these quirks.

Reporting Vespucci issues

It is a truism that software has bugs and while as a developer it would be nice to say that they are all somebodies else's fault, but we are probably are all just as bad as each other with respect to slip-ups. In the case of Vespucci the additional complication is that we are dealing with at least 26 different Android versions and 100s of different devices, each with its own manufacturer tweaks to hard- and software.

So unluckily now and then you might experience a crash. I do have to say outside of provoked crashes and early dev builds I haven't had one for ages, but then I use a relative mainstream device for mapping and don't try to edit gigantic areas, The important thing is to either get the issue fixed, or at least find out how to avoid it in the future.

Those readers that have had the unpleasant experience know that post-crash you will be offered the chance to submit a crash report. We do this with ACRA http://www.acra.ch/ and store the reports on a private acralyser server. ACRA gives us a lot of information on the HW and SW configuration of the device, a short excerpt of the system logfile and a stacktrace indicating what the immediate cause of the crash was and where in the Vespucci or Android code it happened. It does not store any personal information of the user in question, in principle we could ask for an e-mail address, but I would prefer not to for data protection reasons. Note on the side: there are some situations in which we'll produce a stack trace just to document an unusual situation, if you don't get an additional warning in general there is no reason to be concerned.

Now if you experienced a real crash (real: as in Vespucci restarted or stopped completely) please submit the crash report, but further please check our issue tracker and our twitter account. If your problem doesn't seem to be known or not already fixed, please open a new issue pointing out that you submitted a report, this is the only way we can get in direct contact with you. Complaining on googles play store or continuously sending the same crash (don't forget it might be related to your device or your editing habits) wont help.

Happy mapping!

Hacking on Taginfo

We recently blogged about the OpenStreetMap hack weekend in London. In that post we wrote about how Jochen Topf & Harry Wood worked on integrating TagInfo into the OpenStreetMap Wiki. They built a solution to auto-populate the wiki with data from TagInfo based on a Taglists template.

Over to Jochen to explain more:

The recent London OSM hack weekend gave me the incentive to work on taginfo once more and we got quite a few things done on the weekend and the days after. Taginfo now works better on mobile, is faster and we have a very cool tag list feature for the wiki. Lets look at these in turn…

You can continue to read this over on Jochen’s blog.

It was great chatting to Jochen and Harry about the potential of this to help keep our wiki up to date and accurate. If you have any comments or suggested improvements feel free to post them below and we will ensure they get passed on.

Mapillary setup redesign

Having done some Mapillary imaging last year for example by Car or by bike i thought of using more professional stuff.

The more dense the map gets the more important it gets to actually go back and proof something exists as you mapped it. Mapping sidewalks, cycleways, surface and lit to all streets is a complex and time consuming task. So i plan to take images on all streets of my hometown and surrounding so i can do armchair mapping in the upcoming winter.

An old Galaxy S4 with broken cell receipt and broken glass used as a GPS enabled camera. Then some RAM mount gear and a buybits mobile cage you all can find on Amazon. This is all not cheap but worth the money.

Then i got into the pitfall only having a Class 2 MicroSD in the mobile which made problems storing the images fast enough. So that got replaced by a Class 10 or U1 which solved the problem.

Then on to fix the GPS reception problem with the Galaxy S4 in its cage. Reviving the years old Wintec WBT 201 or better known as G Rays 2. Pairing that with the mobile and using the developer mode of the Android and Blueooth GPS feeds the GPS informations to the mobile.

Now you need to turn off all "no shoot conditions" in the Mapillary app. Tilt, Shake, Face Down, Move too slow etc as the cage rattles a little so the app will basically NEVER shoot an image.

The problem left is that some images are upside down or rotated as the sensor said i was holding the camera upside down. Typically i delete those images but the App is not really user friendly in reviewing 1-2K images a day.

Simple 3D Buildings

Mysore Palace ( Kannada: ಮೈಸೂರು ಅರಮನೆ ) also called as Amba Vilas Palace located in the city Mysuru, Karnataka, India.

mysore-palace-1

Started this small project a week ago, looking into Palace photos and OSM wiki on Simple 3D buildings, Kendzi JOSM plugin developed this simple geometry building.

The whole building is marked as building = yes on top of it everything is building:part = yes. Texturing is another important thing in 3D development. Used Hexadecimal colour codes to building facade and roofs.

Kendzi3d is a useful plugin for JOSM for 3D mapping. It renders the building parts immediately as soon you change the height, min_height, building:colour... etc tags with out uploading the data to the OSM.
