Survey on organised editing

Posted by OSMF Data Working Group on 20 September 2017 in English (English)

The Data Working Group is conducting a survey as part of its work on a policy covering paid mapping.

When OpenStreetMap started, it was largely a project of hobbyists contributing to OSM in their spare time. They chose freely what to map and which tools to use, and they took individual responsibility for their contributions.

The continuing growth and popularity of OSM have also brought more and more organised mapping efforts, mostly in the form of companies setting up paid data teams to improve OSM data in specific regions or for specific use cases, but also unpaid groups like school classes that are directed to work on OSM.

These organised mapping efforts are an integral part of today's OSM contribution landscape and, when done well, help make OSM better and more widely known.

In order to ensure good communication, and a level playing field, between individual community members and organised editing groups, the OSMF Data Working Group has been tasked with developing guidelines for organised groups. These guidelines will above all set out some transparency requirements for organised groups - things that are already voluntarily followed by most groups today, like informing the mapping community about which accounts edit for the team.

We have prepared the following survey with a few questions about such a policy to give us a better understanding of what the mapping community expects from such a policy. The survey is aimed at everyone editing (or planning to edit) in OSM, whether as individual mappers or as part of a team, and your answers will help us in fleshing out a draft policy.

Within the scope of the survey, and the policy to be written, we define paid mapping (or paid editing) as any editing in OSM performed by someone who is told by a third party what to map (and potentially also how to map it) and who receives money in exchange. We define other organised mapping (or editing) as any editing that is also steered by a third party, but where no money is paid.

Gravar tracks / trilhas usando gps automotivos

Posted by Tomio on 19 September 2017 in Brazilian Portuguese (Português do Brasil)

As vias dos novos loteamentos normalmente não estão visíveis nas imagens satelitais disponíveis no OSM para edição, em razão da frequência de atualização das mesmas. A solução é percorrer as novas vias, gravando tracks/trilhas gpx para utilizar nas edições.

Realizei alguns testes comparativos, gravando alguns tracks utilizando um gps automotivo Garmin Nuvi 2580 e um gps de mão, o Garmin 76csx.

Para obter uma maior precisão, em ambos gps foram desativadas a função "Lock on road". Isto é muito importante, para forçar o gps a gravar a sua real localização. Sem este procedimento, o equipamento realiza "correções" a fim de coincidir a localização com o mapa visualizado na tela, obtendo um track impreciso.

No Garmin 76csx, o procedimento consiste em:

Nos gps automotivos Garmin Nuvi, o procedimento varia um pouco conforme o equipamento, mas de forma geral:
- linha nuvi 1000 ou superior:
- linha nuvi 2xx e 7xx:
- nuvi:

Após a gravação, foi realizado o efeito comparativo e concluíu-se que a diferença entre os tracks gravados pelos equipamentos é praticamente desprezível:

  • Exemplo 01:

  • Exemplo 02:

  • Exemplo 03:

Assim, os colaboradores do OSM que quiserem utilizar seus gps automotivos para obter tracks para edição, podem fazê-lo sem maiores problemas. Ou podem ser adquiridos equipamentos usados a preços reduzidos, viabilizando os mapeamentos.

Quem tiver interesse, mesclei os tracks do gps Garmin 2580 com o Garmin 76 e subi para as trilhas do OSM:

Kathmandu beckons

Posted by ramyaragupathy on 19 September 2017 in English (English)

Quite excited to be at the SOTM Asia 2017 Conference in Kathamandu this weekend. This year I'll be talking about my OpenStreetMap readiness assessment work and walk through on how the approach varies from prior art, opening new avenues for mappers to explore data coverage.

I'm also collaborating with Jennings Anderson on his contributor metrics analysis & trying to understand how does mapping community health reflects on the readiness work.

If you're at Kathmandu this weekend, do catch me up for more conversation over a Chiya! 👋

Posted by elmoneto on 19 September 2017 in Brazilian Portuguese (Português do Brasil)

Depois de alguns meses de dedicação e aproximadamente 23 mil buildings adicionadas, atingi a meta de desenhar casas e demais edificações em todas as vias da área urbana de São Gabriel (RS). Ao todo, 37 bairros e 3 núcleos urbanos autônomos. Faltam casas que estão encobertas ou que ainda não aparecem nas imagens aéreas, as quais serão adicionadas quando eu ou outros mapeadores formos coletar dados a campo (o que eu considero a melhor parte do mapeamento). A tarefa por muitas vezes parecia interminável mas vendo o resultado final valeu o esforço. O trabalho agora é de melhorar o mapeamento na zona rural de São Gabriel em paralelo com outras tarefas na região central e campanha do Rio Grande do Sul. Espero que com a geometria disponível, usuários sejam incentivados a adicionar informações, como numeração e nomes de estabelecimentos, relativas a cada building.

OpenStreetMap US Mappy Hours Reboot

Posted by mvexel on 18 September 2017 in English (English)

A few years ago I started a bi-weekly video chat for US mappers, called Mappy Hours. They were fun and varied, with topics ranging from tagging discussions to a presentation about OpenHistoricalMap and many things in between.

Then we all got busy and the Mappy Hours stopped. I was recently reminded about them on the OSM Slack channel, and I thought it would be nice to restart them. So here are the details of the first Mappy Hour:

Wednesday September 27 at 5:30pm Pacific Time

We used to use Google Hangouts, but there were problems with that: a limited number of video participants, you couldn't call in, plugins.. There is no perfect solution but I have had success with Zoom so we will try that. You can either download the Zoom client or call in using your phone.

Zoom link

There are local dial in phone numbers for many countries.

The topic for the first Mappy Hour will be State of the Map US. What are you looking forward to? Do you have a presentation you want to promote? Do you have ideas to make the conference even better than previous years? Let's talk! Even if you are not planning to attend SOTM US, I invite you to attend: there will be plenty of time to talk about other things as well.

OSM Analytic Tracker (OSMAT)

Posted by Cascafico on 18 September 2017 in Italian (Italiano)


Tracking vandalisms is often not an easy task. To accomplish this activity I hardly find useful digging in the history of OSM changesets.

Instead OSMAT features a clean list of create/modifiy/deletes and tag changes; the latter one is particularly useful to track "advanced vandalism".

OSMAT focuses on fast detection, so don't expect to configure it on a national base, since rows will start to scroll too fast for spotting problems. For the same reason, OSMAT relies on minimal base of mappers and (quoting its wiki) "Improve[s] team spirit of a regional OSM team/task-force".

The following installation procedure has been brought live on a OrangePi PC single-board computer. Here you can find a regional live instance for Friuli Venezia Giulia Italy.

Docker installation

OSMAT deployment is Docker based, so refer to Davide's Docker installation

OSMAT download

Then download OSMAT sources:
$ git clone

Check docker service

$ sudo service docker status
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled)
Active: active (running) since Sat 2017-09-16 11:40:37 CEST; 2 days ago

OSMAT configure

Once you got docker up and running (I had to upgrade linux kernel > 3.10 for my Jessie Orange Pi) and before compiling container, you have to configure active region.

Default available regions are the ones defined by Geofabrik. For instance, navigate to nord-est, take note of .poly link (nowadays is and edit configuration file:

$ cd osm-analytic-tracker
$ vi config.json
You'll need to replace 3 occourences of default "denmark.poly" with your poly (for instance "nord-est.poly", without any trailing URL).

Optionally, here you can also adjust:

  • map zoom level and time horizon, just search for "map_scale": "6"
  • logging interval, search for "horizon_hours": "48"

Compile container

Once you're done with region & zoom configuration, set your device OS (mine is Armbian, which I've found Raspian compatible) commenting one of the following lines :
$ vi Dockerfile #FROM debian:jessie FROM resin/rpi-raspbian

then compile container:
$ sudo docker build -t osm-analytic-tracker .


Then choose which port to listen (mine is 8889) and run it!
$ docker run -d --restart=always --name=osmat-container -p 8889:80 osm-analytic-tracker

[optional] Customizing

If you need a particular Area Of Interest, I've found easier to add a line in default regions list:

  1. Build a polygon: use JOSM opendata plugin to easily build and save a .poly which will be your AOI.
  2. Publish myAOI.poly somewere in internet
  3. Edit docker/regions.txt adding (or replacing) geofabrik URI's with your URI, for instance:
    $ cd docker
    $ vi regions.txt
  4. Stop, remove and re-run container:
    $ docker stop osmat-container
    $ docker rm osmat-container
    $ docker run -d --restart=always --name=osmat-container -p 8889:80 osm-analytic-tracker

Try it

Go to http:127:0.0.1:8889 and wait for some changeset :-)

If you don't see any changeset, at least you should see the map centered in your AOI and read in the upper right corner "Lag" around 1-5 minutes. Just wait for the next OSM changeset.

State of The Map 2017, Aizuwakamatsu, Japan

Posted by AnisKoutsi on 17 September 2017 in English (English)

This post was aggregated form my personal blog ( )

My first introduction to OpenStreetMap was almost a year ago, when Redon Skikuli, a fellow friend from Open Labs Hackerspace presented me this great project, which I really liked since the beginning.

I started contributing at OpenStreetMap, editing the map using ID editor in the beginning , adding information to the map, co-organizing small mapathons and events at the local hackerspace that I am part of, and telling people I know, advantages of using OSM. As time passed by, I found out, that State of The Map, which is the annual gathering of OpenStreetMap enthusiasts from all around the world, would happen within a few months, in Aizuwakamatsu, Japan.

I applied with a presentation, and a few weeks later I received the confirmation email from Rob Nickerson. I was thrilled to find out that I was one of the chosen scholars by OSM Foundation to attend the conference, and that was a great opportunity to meet contributors from other countries and communities and go deeper into the OSM ideology.

Months passed by, after struggling to get the visa, with the huge help of Dorothea Kazazi, I finally made it.

The moment has come to attend SoTM for the first time !!

Long trip to arrive in amazing Aizuwakamatsu, but the excitement to be there was way more intense.

The conference started. After registering and receiving some swag and goodies provided by the organizing team and a delicious Japanese tea, time to start the sessions. I held my presentation “How to start an OSM Community” during the first day of the event, in the main hall. I explained how the OSM Community in my country was created and how it grew up, I shared my thoughts about essentials that are needed to have a healthy community, gave some tips on how to encourage new people to join OSM and how to create communities based on a country’s historical and cultural background.

Didn’t forget to mention the importance of having more women involved, not only in OSM communities but in every other Free Open Source project.

After answering the questions that were kindly asked by the audience, I was ready to enjoy so many great talks, workshops and lightning talks I spotted on the agenda for the next three days, and a very productive meet-up that happened the third day of the conference, where everyone shared thoughts about how local chapters and OSM Foundation can help each-other grow bigger, and we had the opportunity to share the wish of the Albanian speaking community to become a chapter.

Worth mentioning the dinner that was organized for all the attendees where we enjoyed an exquisite traditional Japanese dinner, an amazing show with Aizuwakamatsu traditional music, followed by the OpenStreetMap Awards, organized by Ilya Zverev, where I was more than happy to announce the winner of one of the categories.

Well, after all I didn’t only get to know so many other OSM related projects that I didn’t know earlier, but also earned even more knowledge, learnt even more tools and ways to contribute to the map, and last but not least, I met incredible people that deeply inspired me. We shared not only our knowledge but also some wonderful moments and memories in Japan, that will remain in my mind for a very long time.

Let’s take a moment to thank the organizing team for a wonderful SoTM 2017 !

As one of the phrases I spotted on one of the presentations says : “ The big OpenStreetMap community is like a big family”

I could not agree more.

Travelled to Madeira for a week at the end of February, staying at the excellent Pestana Grand Ocean Resort hotel. I have been prompted to compile this diary entry more than six months later because of lonvia's user diary entry of 10th September, regarding, and my particular interest, First, though, I must comment on the excellent level of detail in OSM for Madeira; I was extremely surprised, but so pleased, too, of course. It was of help in all ways: our journeys, our walks, and restaurants, even. What a difference it makes! We undertook three walks during our stay: the first, to get our legs moving, from the hotel, directly on the seafront, to Cãmara de Lobos alongside the beach. The second was to take no. 81 bus from Funchal to Eira do Serrado, then walk to Curral das Freiras (Nun's Valley). What a scenic walk! The third was to take no.96 bus to Estreito de Cãmara de Lobos, then walk Levada do Norte (South) to Cabo Girão. We had hoped to walk from Monte to the botanic gardens, also, but there had been a landslip, unfortunately, and the way was closed. Second, lonvia's waymarked trails were excellent in highlighting and naming the officially recognised walks: Madeira is such a complex arrangement of hills that it would be difficult to choose routes otherwise. Together, and continuing to use my same resources on my 'phone, they contributed to a most enjoyable holiday. Finally, I recollect the usefulness of the waymarked trails as I walked sections of the Chiltern Way and created some of its child relations in JOSM.

GSoC 2017 PT_Assistant plugin for JOSM

Posted by Polyglot on 17 September 2017 in English (English)

Giacomo Servadei continued to work on the PT_Assistant plugin for JOSM

Hiking, bicycle and equestrian routes

The plugin is not just about public transport anymore, it can also highlight hiking and bicycle routes and report problems with their continuity. It now also visualizes forward/backward roles, which makes editing them a lot more convenient.

One of the problems I noticed over the past year, was that while fixing public transport route relations, sometimes foot and bicycle routes were broken and the validator didn't warn about this. The other problem is that when bicycle routes fork, forward and backward roles are needed, but they depend on the direction of the way and those little arrows are very hard to see.

Now one leg is coloured in blue, the other in red, which makes it immediately obvious whether the route is mapped correctly and it's easier to know if forward needs to become backward or vice versa.

forked bicycle route relation

Public transport improvements


  • The plugin can now sort stops according to the sequence of the ways in the route relations.

  • It can help with splitting roundabouts, while keeping the route relations that pass over them correct

  • There is a new map mode to add stop_position nodes. If such nodes are added to the first or last ways of the itinerary, the way is split and only the pertinent part is kept.

  • And there is a new map mode to help with ways selection. It will select all ways in between 2 forks, which are suitable for the mode of transport worked on. At the moment this defaults to bus.


There are also some new categories of problems the plugin reports and proposes fixes for.

  • gaps of a single (suitable) way + automatic fix

  • a bug with the detection of relations that could be fixed by simply sorting the ways was fixed.

  • a new category will tell the mapper about relations that end up with less gaps when the ways are sorted. This can help detect routes tagged with public_transport:version=2, which aren't composed of a simple sorted sequence of ways for each variation, but instead still have ways for both/all directions of travel in them.

  • There is a new category for routes that don't start or end neatly on a stop_position node near to a corresponding platform node.

  • The names of the first and last stops are compared to from and to tags in the route relations.

  • A warning is given if the first or last way don't correspond to the first or last stop in the route relation.

Очередной рубеж. За 4 месяца рисования. Вообще то при той недостаточности отрисовки Казахстана достигать такие рубежи довольно таки не сложно. Только рисуй. Хотя это одновременно огорчает. Что так мало отрисованно. Значит активность юзеров в ОСМ Казахстана не слишком велика

OSM Niger au SotM2017, Japan

Posted by ilasolthah on 17 September 2017 in French (Français)

State of the Map (SotM) ou "état de la carte en français" est le plus grand événement annuel qu’organise la Fondation OSM. Cet evenement est à sa 10è edition cette année dont la Founation OSM Japon a eu l'honneur d’accueillir cet événement dans la ville historique Aizuwakamatsu (Aizu Esprits des Samouraï) . La conférence qui a eu lieu du 18 au 20 août a vu la participation de plusieurs personnes de tous les coins du monde entier. Les activités ont ete riches en presentations autour de OpenStreetMap.

Je suis contributeur OSM depuis 2013 et pour la première fois j'ai eu à participer à une conférence de SOTM international. Ceci a été possible que grâce à la bourse obtenu de la fondation OpenStreetMap. J'ai fait ma présentation sur l'effort de contribution de la Communnauté OSM du Niger. Cette session, s'agit de présenter de la communauté, ces efforts et les contributions de la communauté dans l'enseignement et la promotion du projet OSM et des données ouvertes, les différentes activités au niveau national et en Afrique francophone subsaharienne et aussi les projets réalisés avec les données OSM.

Cette participation m'a permis de découvrir l'écosystème OSM à travers les échanges et le partage d'expériences avec les différents participants. Au-delà de la cartographie c'est aussi un cadre de brassage culturel et de de couvertes. chose qui m'a permis d'avoir un apercu sur la culture et l'histoire de Fufushima à travers les visites guidées au musée historique et au Tsuruga castle. On peut noter aussi l'évènement au Tsurugajo castle hall au cours duquel j'ai ont été devoilés les gagants de OSM awards

Au sortir de cette conférence c’était la satisfaction totale sur l’organisation et l'acceuil de cette conférence. J’ai découvert un peuple très hospitalier et très ouverts. Je remercie l'ensemble de l'equipe de OSMF, et la fondation OSM Japon qui n'ont menagé aucun n'effort pour rendre notre sejour agreable tout en esperant se retrouver à Milan, Italie pour la prochaine édition.

Update name suggestion index

Posted by SimonPoole on 17 September 2017 in English (English)

A couple of weeks back I regenerated the data in the "name suggestion index" from a current planet dump, adding a largish number of new entries. The index is used by iD and vespucci to generate canonical spellings for well known brands and apply the correct presets at the same time.

Naturally the raw list contains a lot of nonsense and that's why there are two ways to reduce noise to an acceptable level: a list of (mis-)spellings that are mapped to a canonical value and a filter that removes names that we don't want, for example Bank for banks.

Previously you could only drop names globally, now you can drop them specifically for a type of object. For example in older versions anything with the name "Casino" was dropped, now only casinos with the name "Casino" are (that the reason why in earlier versions the suggestions didn't work for the French supermarket chain of that name).

The was the index works is not perfect, mainly because it is not country specific (and creating such would be, IMHO, too much work), but works quite well even given its limitations.

Now why am I writing this: the update added a lot of names in non-latin scripts and other new entries that need to be checked if they are actually useful, Considering that iD is used by the majority of new mappers improving the index has a direct effect on the quality of their contributions.
