Castles and palaces in Switzerland, including neighboring countries, Germany, France, Italy. The combination of OpenStreetMap + Wikidata + Wikimedia Commons + Wikipedia 1 | Data Members OpenStreetMap, ODbL


  • At the Pacific Visualization conference, Jochen Gertler together with his colleagues won the Best Paper award for his work “Stippling 2D scalar fields ”(mostly maps).
  • [1] Stephen Keller of Rapperswil University of Applied Sciences published the “Map of Castles of Switzerland”. Currently, this is the most complete web map of castles and palaces in Switzerland, including nearby countries (Germany, France, Italy) - right up to Neuschwanstein Castle. A multilingual web application uses data from OpenStreetMap, Wikidata, Wikimedia Commons (images) and Wikipedia. The source code of the project is available on GitLab.
  • The historic.place service has been updated and now shows a new castle map in Switzerland based on data about Wikimedia locks  (de) .
  • The official app of the London Marathon is amazingly used tiles from the OpenStreetMap server that did not cope with the load (probably due to an incorrect their CDN configurations). See also tile usage policy and switch2osm.org as tutorials for setting up your own infrastructure.

Open Data
  • The German branch of the Open Knowledge Foundation reports (de) about new EU 2018/0111 guidelines: reuse of public sector information , which will facilitate access to public information. The new guidelines apply to public sector companies, state that any EU documents should be “open in design” and “open in default” and provide further improvements. However, the EU still lags far behind domestic prohibition on copyright protection, which benefits the work of the US government. < li>


  • Oracle is changing the licensing model for the Java platform. How this affects JOSM usage is discussed on the German forum (automatic translation ).


  • Development Seed has created osm-coverage-tiles that visualize information about infrastructure, in particular, buildings and roads from OSM, to improve verification of machine learning results. Pilar Gabriela Serrano Quispe gives more information in a medium.com article


OSM in the media

  • The Saarbrücker Zeitung website writes (de) Historic.Place and OpenStreetMap, he combined both hobbies and now conducts excursions (fr)/ (de) article on apnews.com tells how they combined and analyzed data from the US Census Bureau, Cal Fire and OpenStreetMap to evaluate evacuation routes for Californians living in areas where there is a risk of fire.


  • On April 26, a daily action on drawing Lesotho (a country in South Africa) was organized by the laureate The Best Cartographer Award in 2018 Tshedy (Matseliso Thobei). In her Twitter, she thanks all participants for their support and words of gratitude. The campaign was held to improve the quality of the map of this state.
  • Colin Blackburn reports that he has kept his word and examined one territory in the Netherlands, which was called "Clothing is optional." He notes that he did not find any evidence that this place was so called.
  • Now going to vote for the new landcover = barren , which is proposed to mark areas without vegetation and with bare soil. However, by this time the majority voted against its introduction. Quite possibly, the comment of Peter Elderson, which he left to his voice, explains the reason for this reaction: "... your thinking [of the one who proposed the new tag] does not correspond to the opinion of the majority of OSM participants" .
  • Started voting for the golf_cart = * key, which is proposed to indicate the possibility driving golfcars or similar small non-speed electric cars.
  • Joseph Eisenberg added a new section to the “Verifiability” wiki about non-verifiable geometries , such as natural = bay (bay), natural = strait (strait) and place = * .However, not everyone supported this initiative, for example, Tobias Knerr made against .
  • Instead of starting the process of discussing the new tagging scheme, Joseph Eisenberg immediately created wiki page for natural = mountain_range , because I thought the tag was already in use in OSM. Currently, almost 80 cartographers have used it, and have marked over 600 objects with them.
  • Joseph Eisenberg created a page for each of the new tags he proposed: natural = mesa and natural = butte . Mesa is a geological formation, also known as the plateau, potrero or tepui. Butt - something like a month, but somewhat smaller in size.
  • Ian S. voted to vote a shortened version of the “Police Institutions” tagging scheme which was recently rejected. Now it consists only of the police = * tag.
  • fanfouer offers to introduce new keys for traction substations ( substation = traction ), to better describe their purpose, and therefore waiting for comments.
  • Anna and Karen from the University of Geography, Heidelber University decided (de) improve the Heidelberg map so that participants in the State of the Map conference in September 2019 can navigate around the city and build correct routes in OSM. They plan to clarify accessibility information, add entrances to various buildings and on site. It would not be Germany, if the very first reaction to this message would not be a proposal to abide by the rules. By the way, to coordinate the action was created (de) wiki page.
  • It turns out that the differences between waterway = river and waterway = canal are not as obvious as one might think. Dave F. started a discussion on this issue, as considered that other cartographers incorrectly mark the channelized sections of rivers near gateways as waterway = canal .


  • Adam Steer shared information about the proposed program FOSS4G SotM Oceania , which will be held November 12-15, 2019 in Wellington, New Zealand, and asks for comments before the end of May when the submission of reports should begin and seminars.
  • Now the is open to receive topics for presentations and workshops for FOSS4G UK, a conference on free and open geospatial software. The conference will be held in Edinburgh on September 19-20, 2019.


  • JOSM team has released a new stable version. version 15031 fixed error , due to which the comment on the change group was loaded, despite the empty comment field on the change group with the last one used. The download_along plugin functionality has been added to JOSM and is now available in the Additional Tools section. As always, there are many other improvements , bug fixes and new features.

They were organized by members of the Chadian community and Togolese cartographers with the support of the International Organization Francophone . Also during the training, a multi-day campaign was held to draw the area near the lakes Itasi , which was held in the framework of the decentralized cooperation "Itasi/New Aquitaine". All of this is documented on WikiOSM in an appropriate way, following the principles of OSM Foundation edited editing.

The project was organized by the World Bank, Potentiel 3.0 and the local OSM community in Democratic Republic of Congo with OSFAC ( video in French ).
  • Deleting articles from WikiOSM remained unregulated. The proposal to introduce relevant rules did not find support . One of the main remarks: along with the rules, complex bureaucratic procedures will appear that only delay the process of deleting articles. Although some of those who opposed this version of the rules, still recognized the need for rules of removal in one form or another. It is possible that over time and an increase in the number of obsolete articles, this question will arise again. In the last issue of WeeklyOSM, we told about a noticeable complaint to a remote page on WikiOSM.
  • flowolf and his colleague started create a free enterprise directory based on OSM (Yellowosm). This was reported in a conversation on Grazer Linuxtage 2019 At the moment, only Austrian enterprises are shown on the map.
