    Earth cake?, Globe cake?, Geo cake?, Map cake! [1] | Photo © 2018 Mikel Maron


  • User 817817 explains in his blog (ja) why he’s mapping surveillance cameras, and he encourages others to map them too. 817817 says that mapping surveillance cameras contributes to both privacy and security and that it will trigger people to reconsider their own privacy. (automatic translation)
  • Thejesh GN wanted to print some maps with Marble in the Kannada language, which is spoken by 40 million people in southern India. He noticed that this language is underrepresented in OSM. He created instructions to fix that problem using iD.
  • Voting has started for highway=toll_gantry, proposed to be used on nodes to denote a transponder or camera gantries to toll bridges.
  • Daniele Santini prepared a proposal for the key assembly_point:purpose= to specify for which kind of hazard – fire, tsunami, earthquake, tornado – an emergency=assembly_point was created.
  • Joseph Eisenberg is proposing the key prominence= for peaks. While the established ele= provides the value for the height of the peak, the new key is intended to indicate how tall a peak is compared to the surrounding area.


  • Frederik Ramm started a discussion on the dev mailing list about extending the range of possible user blocks and making them more granular. The questions raised might not be most appropriate for that mailing list.
  • The Wikibase extension (which we reported earlier), that is intended to store structured tag metadata, is now live. However, response to this promising change has been muted to date.
  • OpenSnowMap.org’s maintainer yvecai has compared the data at Skimap.org and the ski pistes in the OSM database. Neither project is complete so it is hard to estimate OSM completeness.
  • The organisation Potentiel3.0 wrote two tweets [1, 2 (fr)] about the QGIS and mobile data collection training for agricultural engineers at the University of Grande Anse in Jérémie, Haiti.
  • David Morais Ferreira (OSM dmlu) was chosen as mapper of the month by OSM Belgium.

OpenStreetMap Foundation


  • [1] Mikel Maron tweeted how a cake should look like if it was made for mappers.
  • The INTERGEO fair, which will take place in Frankfurt from 16th to 18th October 2018, will also host the OSGeo-Park this year. OSGeo-Park informs visitors about Open Source GIS, free geodata, GIS technology, and OpenStreetMap. The organisers are still looking for a A0 printer to print maps on the fair. The program is still a work in progress.
  • HeiGit will present Openrouteservice.org at INTERGEO 2018 (Frankfurt, Germany 16th-18th October) in the booth of the German Federal Agency for Cartography and Geodesy.

Humanitarian OSM

  • Nicolas Chavent tweeted from Haiti about his preparation of his second OSM, open data and GIS training week.
  • HOT prepared a short analysis about the use of available imagery sources. It shows that the majority of HOT tasks use Microsoft’s Bing imagery.
  • RichRico wrote a post about the cooperation of Development Seed’s data team with HOT in the previous months and detailed the projects they were working on.


  • In Haïti an 11 day workshop was organised from 17 till 28 of September. During the first 2 days participants were taught field surveying, JOSM, uMap, and QGIS for editing and rendering the data.


  • Klokan Technologies tweeted about the simplification of map creation with its MapTiler Cloud product. According to a blog post it is possible to design a personalised map with only five clicks.


  • In Belem, Brazil, there is an annual religious parade that attracts two million people. The state IT agency Prodepa has created an OSM-based online map of the "Círio de Nazaré" procession including prominent contact points, specially set up medical stations and time restrictions on road closures.

Open Data

  • The Open Data Institute launched a fund to encourage local governments in the United Kingdom to release geospatial data as open data and to explore collaborative approaches to data collection, management and use by the Ordnance Survey, OpenStreetMap and other open data or civil society groups.


  • The Suspect Lists of BRouter, that can help finding errors and inconsistencies in the road network, are now available worldwide.


  • Sascha Fendrich from Heidelberg University calculated the size of the OSM history data in terms of raw data as it would be represented in systems programming languages such as C and Rust and derives some interesting numbers in comparison to data structures in XML.


  • Daniel Koć, maintainer of OSM’s main map style, just announced the release of a new OpenStreetMap Carto stylesheet. The changes in version 4.15.0 include new colors for gastronomy objects, farmland and societal amenities, rendering implementation of man_made=wastewater_plant and man_made=water_works, new icons, missing country label fixes and many others.

Did you know …

  • …. Map Compare, which can also be used to show the different addressees of the OSM mapping. The example of Falkirk in Scotland shows that on OSM, what can be seen on the ground is shown as far as possible. A comparison of video and map are worth watching.
  • MapRoulette? There are always possibilities to improve the OSM data.
  • … the tool Who’s That? If you want to lookup the former name of a mapper or you have the former name and want to find out the current username, the tools will do the job.

OSM in the media

  • The Factor Daily wrote a comprehensive article about OSM. It covers OSM’s relation to Google, what market potential is estimated in the map industry, why companies switch to OSM and the relation to government bodies, the Indian, here in particular.

Other “geo” things

  • Locusmap tweeted a picture of its map app running on a Samsung Gear under Samsung’s proprietary smart watch operating system Tizen.
  • Emily Badger published an article with an interactive map in the New York Times about how connected locals in the US are on Facebook.
  • There is not much time left to take pictures for #WikiLovesMonuments 2018, the world’s biggest photo competition around cultural monuments.
  • COBI.Bike proposes hardware to interface with your bicycle or e-bike. The app for iPhone is described in this article (de) (automatic translation). It exists for Android too. It uses OSM data for navigation.
  • Linda (Hecht) Stevens wrote an article on medium.com about her view that the availability of geospatial data like imagery, base maps and localised information, fuel a GIS revolution that has yet produced new spatial analysing tools like for 3D rendering or data visualisation.
  • kerook.eu published an article about nice looking pouches with OpenStreetMap renderings printed on the fabric.
