Dhaka College; The Statistical Team not only Dynamic

Posted by Sawan Shariar on 6 March 2018 in English (English)

“I will do it. I want to do. I wish I will do it one day…” those sentences are not for this team. There is no place for a single performer. It's a team. Here is not any places for the word ‘I’ without the word ‘We’. They are loves to say “We did it. We had done it.” The team is know that The word ‘We’ is more stronger than ‘I’. But here is a problem is that we don't want to show the team’s work more than they talks. But by this blog we are wanting to inspire others for a competition of humanitarian work. We are a ultimate ghost. No one know us but feels so much by our works.

Missingmaps Leaderboard:

See the top 10 mappers of the missingmaps leaderboard. Here staying the three mappers (red marked).And if you see top 50 you will find more mappers of the team. missingmaps leaderboard


The team is contributed more than 50% mapillary photos. YouthMappersBD

Not only the statistics are the main issue. We have done all the works with maintaining quality of map data. We are already contributed more than 1.5 million buildings with around 55k km highways. All the contributions are maintaining quality.

We are ready to work for humanity. We was in action on Malaria Elimination, Nepal Earthquake, Tanznia Project, South Asian Flood or Rohinga Crisis. We achieved Chapter Partnership Award 2017 and took 3rd place on the YouthMappers ‘Mapping to End Malaria’ Challenge: Round-03 2017

It is realy true that all the great achievement was came by the teamwork. So that every team is always need to works together to achieve the big things. Best wishes to all chapters. See you all in the field of winners.

FANGA e.V. - HOT Task in Banfora - Burkina Faso (West-Africa)

Posted by spongezob on 6 March 2018 in English (English)

Me and my friends founded a help organization in Banfora (Burkina Faso) called FANGA e.V. in 2010.

We help children and young people of the poorest families in Banfora with school and job education and medical support.

One problem for us is that these families are scattered all over the town of Banfora (about 80'000 people) and our staff struggles to find the homes because there are almost no street names and house numbers.

That's why we startet GPS tracking and OSM mapping a couple of years ago. We mapped now almost all streets in Banfora, but it is still quite difficult on the ground with a printed map or on a phone to find the right buildings in the chaotic slums with no roads between the buildings.

So we contacted the HOT Team and together we are mapping now all buildings in Banfora. Take a look:

OSM Awards as a thermometer on diversity in the mapping community

Posted by SeleneYang on 6 March 2018 in English (English)

The call for nominations for the OSM Awards de 2018 is now open it the winners will be presented during the SOTM en Milano, Italy at the end of July.

While this is a fairly new initiative to celebrate the achievements of people, groups and projects that support OpenStreetMap, I couldn't but notice the fact that in this two years, in all categories the percentage of women nominations is really inferior than men nominations.

This are the initial categories (Each category holds 5 nominatios):

  • Core Systems Award
  • Innovation Award
  • Influential Writing Award
  • Greatness in Mapping Award
  • Expanding the Community Award
  • Ulf Möller Memorial Award

For the OpenStreetMap Awards 2016, out of 30 nominations, only 3 women were nominated (none for the Greatness in Mapping Award); for the OpenStreetMap Awards 2017, where there were more awards (added: Improving the Latin America Award, Improving the Africa Award, Improving the Asia Award ) only 5 women were nominated.

Now, regarding to the winners, in 2016, no women won an award; in 2017, Geochicas were the only women who won an award. (A disclaimer about this, groups where there was participation of women did win, however no award - apart from ours - was obtained by a woman or a group led or conformed only by women).

The nominations are made by the community, just as the winners are chosen by the community, so my conclusion with this, and because we're getting closer and closer to the #8M, International Women's Day, is that although we might not be many women in the mapping sphere, our achievements are almost never recognised as the contributions made by our male colleagues. From Geochicas we launched the series #WomenMappingTheWorld, because we are not going to allow history to be told from one perspective, and we are not going to let our contributions be forgotten neither the struggles we've gone through to occupy spaces that have been historically denied to us.

So I will not congratulate you on International Women's Day, but I invite you to continue mapping, to continue to work into building more diverse and inclusive communities, because in the multiplicity of voices and experiences is where the true essence of community lies. Remember that the map is a reflection of its mappers.

Celebrating Open Data Day 2018 with Open Mapping

Posted by GOwin on 6 March 2018 in English (English)

image Happy to see folks from various communities coming together to celebrate ODD with us.

Last Saturday afternoon, we celebrated Open Data Day 2018 in PUP San Juan, with several volunteers from OpenStreetMap Philippines and the local FOSS4G chapter facilitating the parallel workshop sessions we ran.

We mark Women in History month with a beginners' workshop led by the P̶o̶w̶e̶r̶p̶u̶f̶f̶ ̶G̶i̶r̶l̶s̶ awesome ladies of the OpenStreetMap volunteer community 😹:

For intermediate users, we offered a session on Geopandas, and another for Adjusting Imagery Offsets and alignments: image

Meanwhile, the unconference session included a couple of lightning talks, and several impromptu ones that made the discussions more lively and interesting: image

We had students, NGO workers and volunteers, academics, developers, and GIS specialists. We had a good mix of community enthusiasts, private sector representatives, and some civil servants.

We have a number of participants who traveled quite a ways to participate.

image Aaron from the Peace Corps is working with the local government of Carigara in Leyte, and he's been supporting the municipal DRRM office in their effort to comprehensively map their town. He travelled a few days ahead of a scheduled trip to Manila, to join the activity.

image Pierre showcases their activities in the YouthMappers chapter of the FEU Insititute of Technology.

image Martin is flying out of the country that same evening but decided to "drop-by" and participate in the event. His work on LIDAR and his experience with open data, contributed a lot during the unconference discussions.

image Ayoo did an impromptu demonstration of WebSafe, as a response to a question from an unconference participant. He used to work with Project NOAH, as a developer of Websafe.

There are many others who selflessly shared their time with us. We're grateful you came over. It wouldn't have been the same without you.

A special shout-out goes to the crew of volunteers from the university who provided general assistance throughout the event: image

More photos from the event are now online.

Risks of editing nearby high voltage power lines (humour note)

Posted by PierZen on 6 March 2018 in English (English)

There are thousand of kilometers of 735KV power lines over the Quebec territory. There are often trails under these lines and road crossings. While monitoring the edits to these power lines today, I realized that many contributors had again connected roads to the power lines.

Let me describe this interesting case.

Risks of editing nearby high voltage power lines

A few years ago, a dog park was added plus a nearby parking under a 735KV power line. On the nearby boulevard, the connecting segment between the two sides of the road was moved closed to the Power line and clipped to it. Then a road navigation specialist working for an OSM partner company did narrowly edit modifying highway=tertiary to highway=tertiary_link.

Those people should look around. It is quite dangerous to edit this way. If QA is done so automatically by humans, should we add some artficial intelligence in the editors to detect such problems, and why not give a mild electric shock to contributors!

Gladly, the contributors are still editing to OSM. Let's hope that no one lost their dog connecting to the power line! And that they will learn editing in a virtual world «to look sideways».

Open Data Day 2018

Posted by GellieA on 5 March 2018 in English (English)

As we all celebrate Open Data Day 2018, mapping enthusiasts and volunteers gathered and held events all over the world to celebrate this event. I had the chance to attend an event in San Juan, PH to volunteer and give a talk about features of OpenStreetMap. Open Data had been very useful in all aspects and the progress in its objective in mapping the whole world and providing this data for all users had been evident over the years. Beginner workshop on OSM editing using iD-editor The event had been a venue to meet other mappers and to share existing developments in Open Data, which are included in the workshops as well as different projects and efforts made by volunteers through the lightning talks. Beginner workshop on OSM editing using iD-editor I had a chance to help in assisting a workshop for beginners on iD-editor and HOT OSM Tasking Manager. So glad to have shared insights with them, and to discuss interest in maximizing the use of Open Data in their respective fields.

Bad Weather = Bad Imagery

Posted by apm-wa on 4 March 2018 in English (English)

March 1-2 I traveled to Yoloten and Mary, and passed through Tejen, and tried to collect ground-level Mapillary imagery...during and after a rain storm (unusual in arid Turkmenistan, but not unknown in winter). I must apologize for the poor quality imagery. It was just too dark and gloomy. I collected some useful data and have added information to the maps of Yoloten, Mary, and Tejen (including Tejen's only hotel, which charges 6 manat or $1.71 per night). Nonetheless some of the imagery is less than marginal. Sorry! At least I added some street names to these towns, as well as some major POIs.

Today Ann and I cruised the former vilage of Gokje, now officially a neighborhood of Ashgabat since it was annexed, and collected street names, POIs, and fresh GPS traces for streets that have been created in the past year or so. Some streets had absolutely no signage at all. Not sure how we'll find the names for them.

Issues with Japan imports

Posted by bdiscoe on 3 March 2018 in English (English)

I've run my find_small_displacements program on Japan, and found some problematic imports with a large number of densely overnoded features, here are some:

  1. Bad import of natural=wood around Fukuoka. These were tightly spaced, yet also wildly inaccurate, off by as much as 80 meters and covering lots of non-wood areas, even covering motorways. I've reduced most of them, and aligned a few areas, but there's lots more to align. The original upload was in 2010 with changesets like this one.

  2. Bad waterways, especially in Hokkaido and Kyushu, but also across the country; these are not just overnoded but also overtagged, consider this little stream near Taketa, Ōita:

  • KSJ2:COP_label=1級指定区間
  • KSJ2:DFD=流下方向不明
  • KSJ2:LOC=c03671
  • KSJ2:RIC=8909180118
  • KSJ2:RIN=軸丸川
  • KSJ2:WSC=890918
  • KSJ2:curve_id=c03671
  • KSJ2:filename=W05-07_44.xml
  • KSJ2:river_id=gb02_03671
  • layer=-1
  • name:ja=軸丸川
  • name=軸丸川
  • note:ja=国土数値情報(河川データ)平成18年国土交通省
  • note=National-Land Numerical Information (River) 2006, MLIT Japan
  • source=KSJ2
  • source_ref=
  • waterway=river


Issues with this little waterway:

  • Poorly aligned; off by 20-60 meters in all directions.
  • A large number of tags that belong on the changeset, not the feature; to its credit; this wasn't a practice back in 2010 when it was imported.
  • Overnoding, using 1085 nodes for what is well represented by 40 nodes.
  • It's tagged "river", but is clearly a small stream.
  • "layer=-1" for every single waterway.

Also somewhat alarming, JOSM does not show all the tags (!?), the "KSJ2:" tags are present on the feature but do not appear in JOSM's GUI. I could not find any option in JOSM to make these key/values show up! Perhaps a JOSM expert could weigh in, or I should file a ticket.

The return of the OSM rank table

Posted by bdiscoe on 3 March 2018 in English (English)

To follow up from my previous post, I did some further work on generating and putting online a table of OSM node/way ranks table

The data that's there right now is from today (2018-03-01) and the deltas are vs. 2 weeks ago (2018-02-12).

Standard disclaimer: Last-modified-rank is only vaguely related to contribution, there is no way at all to measure actual quality or value of contribution across users, because it's subjective, and users are very different from each other. However, this table can be very useful for an individual mapper to see how their amount of contribution changes over time, and to identify, for example, accounts that are moving up rapidly which usually indicates they are doing an import. Similarly, if your rank moves down, it can mean that someone (correctly or not) has modified or deleted your mapping work.

For those curious about the technical mess that's currently involved, here is what I did:

  1. Download of the weekly planet file from Planet OSM (39 GB), this takes around 12 hours.
  2. Running a small Linux C++ app that uses Osmium to parse the pbf and generate a CSV of users along with number of nodes and ways that they are the last modifier of.
  3. On Windows, running SQLiteStudio to ingest that CSV as a table in a database.
  4. Run a C++ app that uses SQLite to query the database and generate the HTML output.
  5. FTP that HTML up to a server.

Custom Area (Orphanage grounds)

OSM Scout Server, version 1.4

Posted by rinigus on 28 February 2018 in English (English)

After more than a year of development and 38 releases, I would like to give an update on the status of OSM Scout Server. The server is targeting mobile Linux devices as a drop-in replacement for online map services providing map tiles, search, and routing. As a result, an offline operation is possible if the device has a server and map client programs installed and running. Since its tailored towards mobile devices, the server has been successfully used on devices with as little as 1-2 GB of RAM.

At present, the server can be used to provide:

  • vector or raster tiles for other applications;
  • search for locations and free text search;
  • search for POIs next to a reference area;
  • calculating routes between given sequence of points.

User's guide is available at that describes how to set it up for Sailfish OS.

While started as a wrapper to libosmscout, it now incorporates several other backends:

To use the server, you have to start it and configure the client to access it. With the help of the users, we have setup the distribution of maps in relevant formats that can be downloaded to your device. So, usage is rather simple: through server-provided GUI, users can select areas they are interested in, download, update, or remove them as needed. During the normal usage, server GUI is invisible and the server is started automatically via systemd-provided socket activation when user's map client tries to access it. As a result, you have ability to use offline the map clients that are developed for online operation. It allows also to use the same offline maps in multiple applications, a strategy that has been successfully implemented by several applications in Sailfish OS.

Most, if not all users, are coming from Sailfish OS, but it should be relatively easy to adapt the server to any Linux. Already now it can be used from the command line, although the interface could use some adaptations to simplify management of the maps. However, taking into account that the server if written in Qt (C++ and QML), writing OS-specific GUI would probably require relatively small amount of time if done through QML.

Major Changes in Central Park Mall Jakarta

Posted by Reinhart Previano on 24 February 2018 in English (English)

Changeset details:

The Central Park Mall is one of the popular shopping malls in West Jakarta, Indonesia. It is also inspired by the design of the Central Park in New York City.

This mall has a park for visitors to walk around, called the Tribeca Park. Aside from that, this mall is also connected to the Tribeca (a 2-storey section of Central Park Mall consisting of several restaurants) and Neo Soho (the shopping mall below the new Soho apartment near to Central Park). These malls are owned by the same developer, PT. Agung Podomoro Land.

In this changeset I added the new Tribeca (mall) section at the other side of Tribeca Park, including the skybridge connecting Tribeca ↔️ Central Park ↔️ Neo Soho. I also added more details on Tribeca Park itself, including added new footpaths, restaurants, ponds, fountains and a new escalator. There's 1 more pond left unmapped, as I need to re-check on site for the accuracy of its position.

So far, here's the changes I made to this shopping mall. As of now, there might be some mistakes in my changes to, which I will fix it later.



And here's how my work is compared with Google Maps (as of 25 February 2018):

How should I tag a surf shop/cafe

Posted by ConsEbt on 24 February 2018 in English (English)

Hi everybody, I'm looking for suggestions to improve the tagging of the Surf House Dubai which I have [](added today).

Now I did add some tags to the surf shop as suggested by the wiki however I'd like to have some comments.

  • how should sale and renting of surf, wake and stand up paddling boards be tagged?
  • how to add the surf school?
  • how to add the surf shop - they sell board, parts, tee shirts, shorts, sunglasses, sunscreen etc.
  • how to add Yoga classes

What are your suggestions?

An OSM Logo for Translation Projects

Posted by dcapillae on 23 February 2018 in English (English)

Some time ago, the OSM community in Spain had a discussion to add a country template and choose a new image for our wiki page on the OSM Wiki.

The OSM community in Spain has been using an OSM logo with the letters "ES". This logo was the same one that we were using in the WikiProject Spanish translation.

The Spanish-speaking OSM community in the world is not limited to Spain. Therefore, to avoid confusion between OSM Spain and OSM "in Spanish", we have changed the logo for this one, a simple and more generic logo which can be used in your OSM translation projects and wikiprojects.
