  • Nuno Caldeira announced on Twitter the excellent work done by the newly created Portuguese OpenStreetMap Telegram group mapping buildings on Porto Santo island, in the Madeira archipelago. They will do monthly mapping challenges, such as this one, to improve OpenStreetMap in Portugal.
  • The decision of the StreetComplete maker to create challenges for adding default values like foot=yes on highway=residential or access=yes on amenity=playground caused lengthy discussions on the tagging mailing list and the forum (de) (automatic translation).
  • Tshedy reported on the MapLesotho blog about an exhibition at Avani Maseru which was held with the help of Fingal County Council and Action Ireland Trust. The «tremendous progress from 2013 to 2018» in Lesotho was featured as image of the week on the main wiki page.

Humanitarian OSM

  • HOT has recently held a Tasking Manager Stakeholders’ Workshop in Washington, DC at which development goals for 2019 were discussed. The focus will be on the functionality to group users into suitable teams based on the users’ backgrounds, statistical features to improve mapping projects and their data quality, the introduction of machine learning workflows into mapping and the observation of usability and user flows.
  • HOT features an article from Peter Ward from the GAL School in Cusco, Peru about the geodata collection for testing their hypothesis that closer rubbish bins means less rubbish on the ground.


  • Lukas Loos, from HeiGIT, introduced a first beta version of the OpenStreetMap History eXplorer (ohsomeHeX). It uses ohsome (OpenStreetMap History Data Analytics Platform) to aggregate OSM data of a first set of selected features into a set of world-spanning hexagonal grids in a configurable temporal resolution. The goal is to allow the exploration of the history of OpenStreetMap data in time and space at varying scales. Further improvements are in the pipeline.
  • Utagawa Hiroshige is one of the great masters of Japanese printmaking. George has created an OSM-based map that geolocalises «impressive images of Japan’s great landscape» made by Utagawa Hiroshige. Antoine Oury has written an article about this on ActuaLitté. (fr) (automatic translation)

Open Data

  • On 13 February 2019, the Brandenburg state government, Germany, passed a bill amending the Surveying Act and providing for the future free use of geodata by surveying authorities. With the amendment to the law, digital geodata will, in future, be made available to the surveying authority free of charge. The offer covers nearly 330 digital data records and data services altogether. These include, for example, high-resolution aerial photographs, maps of roads and properties or the representation of entire landscapes and elevation models. Brandenburg publishes its open data on the Internet portal DatenAdler.de under the license dl-zero-de/2.0.
  • The European Union has launched the third Eudatathon. Participants, who are asked to develop apps and visualisations using open data made available by the European Union, can win prizes of up to €15,000.
  • Ellen Tannam published an interview on siliconrepublic.com with Séan Lynch, the man behind the project openlittermap.com. In the interview he explained his motivation, the benefits of OSM’s open data model and the hopes he has for his project in light of the global litter crisis.


  • The OSMF Licence Working Group has written a Licence Compatibility guide for our current licence ODbL 1.0 and made the evaluation results of the Linux Foundation’s «CDLA (Community Data License Agreement) Permissive» licence available.


  • On Twitter, Quincy Morgan presented a preview of an upcoming feature for the iD-Editor, a tool that shows validation issues to the user while editing. In response to an enquiry from Pierre Béland, Quincy explains that, for example, the upload of untagged objects with area=yes will be blocked. A test version is available here.
  • The WordPress plugin OSM from MiKa is now compatible with WordPress 5.0. This version of the plugin supports the «Classic Editor» and the new «Gutenberg Editor». MiKa has also implemented 200 new icons and support for the humanitarian OSM style.


  • OSM’s main map style, Carto, has received another update. As the maintainer, Daniel Koć, wrote in his OSM diary, version 4.20.0 has added the rendering of boundary=aboriginal_area and boundary=protected_area with protect_class=24. The new version also dropped support for leisure=common, lightened major buildings and added support for oneway arrows for footways, cycleways and paths as well as a variety of other improvements.
  • OsmAnd was released in version 2.5 for Apple’s iOS operating system. The most notable new feature is access to their OsmAnd Live subscription. The app can be downloaded from the iTunes Store.

Did you know …

  • You might have stumbled across fictional data in OSM. Now you can point the authors of such unwanted data to opengeofiction.net. Martijn van Exel asks for help to grow his fictional town and connect it to the rest of the world.
  • Following her tweet that kerbs are become increasingly important nowadays, Daniela Waltersdorfer published an article about kerbs, why she thinks their importance is growing, opens questions with regards to mapping them in OSM and how «curbs»—or, as they should be correctly named «kerbs»—should be added in OSM. She draws special attention to transition points, i.e. where kerbs are lowered, as these are important features to pedestrians, cyclists, and especially to those with reduced mobility. On Twitter, Tobias Jordans points to the parking lane viewer/editor on zlant.github.io as an easy way to add parking information to OSM.
  • … about the supplementary descriptions of the tags used for representing roads and paths as areas, resulting from the original proposal by Marek_kleciak? In 2018 Tomasz_W wrote wiki pages for area:highway= pedestrian, footway, path and cycleway, which are, however, currently at odds with the rules defined in the original proposal.

OSM in the media

  • The Berliner Morgenpost used Hans Hack’s Figuregrounder tool to create a quiz that challenges its readers to identify Berlin locations on the basis of the building outlines from OSM data.

Other “geo” things

  • Mapbox published a community impact summary for 2018, which highlights Mapbox’s social engagement and details some of the 167 non-profit projects they support.
  • Listverse.com shows ten areas on Google maps where the borders between states are not clear.
  • Users of ESRI’s ArcGIS Online have already contributed vector data and aerial images for background maps («Community Maps»). Now ESRI also allows users to edit these data. The edit review process takes one week and inclusion in the main database takes up to three weeks. Needless to say, OSM is a bit faster.
  • The New York Times used the Openrouteservice API to derive walking distances from major subway stations in New York City for their analytical piece «Where the Subway Limits New Yorkers With Disabilities».
  • Dmitry Filippov, a student of “Information technology and applied mathematics” at Moscow Aviation Institute (National Research University), created a startup, “Heavy Geeks”, where he transferred the map of the entire real world into the game “Parallel 42”.
