However, most commentators on the mailing list of "tagging" believe that it is better for it to use other tags, such as, asphalt:type=*, asphalt=whisperor noise_reducing_surface=yes.
  • The iD appeared tag for what is forbidden in most countries shop=cannabis.
  • The changing table tagging scheme ( changing_table=*), developed by Velor Naram, received mixed reviews after it was voted on.

Do you know …

  • ... to please Christopher Beddou (Christopher Beddow), Pascal Neiss said editor Deriviste in statistics participants the OSM " How DID You a Contribute ".
  • ... about the advent of Harry Potter Wizards Unite is a new augmented reality game from Niantic , creators of Ingress and Pokémon Go . The game Pokémon Go became known in the OSM community as a reason for constant dubious edits because it used OSM data for maps and game data. These edits were mainly parks added by gamers in the hope of increasing the number of Pokemon creatures in the right area (the so-called 'spawn rate').
  • ... Site Richard Feyhersta? This is a cycling website using tags surface=or other OSM bike related data to make it as useful as possible.

OSM in the media

  • The Internet portal has published (automatically translated ) an article about Franco Benedetti ( @mweper ) from the small Argentinean town of Funes , who cycling through it makes his map in OSM more accurate. In this he is helped not only by Mapillary panoramas, which he himself removes, but also by Wikipedia.

Other “geo” events

  • Pascal Nays uploaded all his presentations about OSM (most of them in German) to GitHub .
  • The online magazine Entre-Temps described the work done by the Old Maps Online portal on digitizing and geo-referencing historical maps from libraries around the world over the past 10 years. They managed to find and digitize not only old maps of many cities, but also such “diamonds” as the “ Orbis terrae compendiosa descriptio ” by Mumoldus Mercator (1587).
  • Guy Schrubshall of Friends of the Earth (UK) wrote a book on land ownership in England - Who Owns England ( review by The Guardian ). For several years, he spoke in his blog about the details of the study, which in the end is easily the basis of this book. For example, not so long ago, he drew attention to the fact that almost 17% of the country's territory is not registered in the Land Registry (cadastral registration authority in the UK).
  • May 2 marks the 500th anniversary of the death of Leonardo da Vinci . He drew maps and city plans, as if he had seen them from the air, for example, in 1502, he executed the plan of Imola in this style . A short film from VOX details how he did it.


  • The founder of the OSM office in Ghana Enok set Nyamador entered the master's course in GIS technology in Munich. Unfortunately, he was not able to get a scholarship for the Erasmus Mundi program, and now he is trying to raise funds for his studies through the Go Fund Me crowdfunding platform .
  • Mexican TV channel UNAM did an interview with representatives of the OSM community-Mexico Miriam Gonçalo and Celine Zhakin.
  • Valery Trubin began a series of interviews ( 1 , 2 ) with Russian mappers. He is interested in how they came to OSM, how they see his future and what they want to change in this project.

  • Maitray Das, a researcher at Northwestern University in Evanston, Illinois , spoke about his work on gender analysis of the contribution of OSM participants to the United States at the ACM CHI 2019 conference held by the Computer Science Association . He analyzed the edits of the 2 thousand most active users who noted or edited POIs. Depending on the specifics of the POI, the information entered (in the author’s terminology) was either “masculine” or “feminine”. Previously, where it was possible, the gender of the participant was determined. As in other works, it was concluded that 95% of OSM users are men, but it cannot be said that the information entered is determined by the influence of gender.
  • At the end of April, a paper atlas of the city of Pokhara (Nepal) was released , which was prepared using data from OpenStreetMap, as well as the Geonode web portal (Secondary Cities - 2C project). With the support of the 2C Pokhara project, Kathmandu Living Labs (KLL) collected on-site data. KLL also interacted directly with the local administration, which allowed to add quite a lot of POIs related to healthcare, water supply, education and business.


  • Robert Bell (a member of Itsamap! In OSM and bjjptq in Reddit) gives a very detailed description of how they accessed local data and then imported it into OpenStreetMap.

  • Over the past months, the HOT team has studied the workflows of mapping and checking information in the Task Manager to prepare it for a major update. It is planned to introduce machine learning, which will entail even greater use of open data. HOT Blog Leila Pinho talks in detail about how they work to improve data quality, increase the speed of mapping and increase the percentage of users who are willing to participate in the project regularly.

Open data

  • The UK Department of Industry supports the local government initiative to make transport data more accessible for various purposes. One of the transport providers, Nottingham City Transport, recently announced the opening of a data set to achieve this goal.

  • In response to our article last week about Oracle licensing changes in Java, JOSM developers published a statement explaining that nothing has changed for the free version of Java, OpenJDK or Oracle JRE 8. Therefore, licensing changes do not affect JOSM and developers recommend continuing to use the current version Java, apply any updates and wait for the publication of OpenJDK, published by the community, which will be available on each platform.
