weeklyOSM 346


About us

  • Dale Kunce accuses us of selective news coverage about HOT and points out the Validation Fridays. As barely 50% of the added data is validated till date, HOT hopes to have a quality gain and more feedback to the mappers, who are new mappers in many cases, through their initiative.

  • Trudy Namitala describes in a HOT blog post why we need women and girls in mapping. Hint: Especially in Africa women often lack the information about help facilities for gender based violence, family planning or maternity services. Look at the list in the wiki.

  • Emir Hartato announces the completion of his Masters thesis on Volunteered Geographic Information (VGI) for Disaster Management. However, his full work may be published only after review.

  • Various people, including Simon Poole, have expressed surprise that HOT is advertising on Google. Are they running short of volunteers? Do they want more donations? Let’s not forget that the OSM Foundation’s donate link will still happily take any spare cash that you might have…

weeklyOSM 345


About us

  • The weeklyOSM team happily switched from Slack to the open source software Mattermost for internal communication. After tests conducted on framasoft‘s framateam, a dedicated instance is now up and running thanks to FOSSGIS.


  • Inspired by the German OSM-Blog Wochennotiz № 343, and a previous discussion in the German forum, Ogmios wrote an article about the quality of recycling stations and how to improve their tagging. Also there is a new QA page for recycling tagging.

  • Arun writes about broken relations in river banks and wants a good guide to correct such errors. Christoph explains in the comments why there is no easy answer.

Humanitarian OSM

  • Pete Master leaves his job as Missing Maps Project Coordinator.


  • After the ticket about the context menu on the OSM main page had been closed (we reported earlier), the discussion continues on the dev mailing list. Though many who were criticising Tom Hughes, didn’t notice was that the desired feature was actually removed by Leaflet and not by OpenStreetMap.

  • The surveying authority of the German state of Saxony has, after much negotiation, allowed (automatic translation) the OSM community to use WMS services with aerial imagery and topographic maps as a data source.


  • A German Magazine reports (automatic translation) about a tool by Simon Lührs. This enables urban planners to easily generate figure ground plans out of OpenStreetMap data.

Did you know …

  • … the Fullscreen Map on sammyshp.de? Besides its full-screen mode, the Leaflet application offers interesting features such as hillshading, a history of views, a functional context menu 😉 (show the current tile, check its status and request re-rendering), and a distance meter.

OSM in the media

  • Following recent political events, a French TV show tries to know where each member of parliament stands on simple questions regarding transparency. The results are displayed on an OSM-based map.

Other “geo” things

  • Nyall Dawson explains the new map coloring algorithm that will be present in QGIS 3.0.

  • Adam Rousell and Alexander Zipf from the GIScience Research Group at the University of Heidelberg publish a paper, which shows a new pedestrian-based navigation service. "Unlike car-based services where instructions generally are comprised of distance and road names, pedestrian instructions should instead focus on the delivery of landmarks to aid in navigation."

  • The OpenHistoricalMap is online again, but changes after May 19th 2015 are now lost, as Rob H. Warren at the mailing list reported.
