  • Data curator arredond explained how working on map layers for the Felt company was an opportunity to find and correct tagging errors.
  • In the fourth part of a series about the specific challenges of working with map data, Daniel Mescheder wrote about the importance of tracking changes.
  • MarcoR noted that there are templates (KeyDescription and ValueDescription) in the OSM wiki that are used by taginfo to display some useful information to the user. Since the same information is included in the data element associated with the feature page, some wiki users in good faith truncate these templates to their minimum (e.g. ‘{{KeyDescription}}’), preventing taginfo from retrieving the data.
  • willkmis shared a personal view on urban road classification from a North American perspective.
  • The proposal for county, city and local highway networks in the United States was approved with 17 votes for, 0 votes against and 2 abstentions.


  • Amanda McCann wrote about the new moderator team and etiquette guidelines for the talk and osmf-talk mail lists.
  • Amanda’s work report for May 2022 is available online.
  • The OpenStreetMap Taiwan Community (OSMTW) gathered for its second workshop. Whether participating on-site or online, the participants worked very hard to map on OpenStreetMap or uploaded related images to Wikimedia Commons. Even during the peak of the COVID-19 pandemic in Taiwan, there were two geographic teachers who attended the workshop to learn more about OpenStreetMap, and how to use OpenStreetMap in the curriculum. OpenStreetMap Taiwan will use the resource supported by the alliance grant from the Wikimedia Foundation to support related workshops scheduled from March 2022 until February 2023. OSMTW is dedicated to organising at least six street-view expeditions and six edit workshops.
  • Zhengyi Cao and Chris Park briefly reported on their projects in this year’s GSoC.
  • Ed Freyfogle talked to Ilya Zverev about mapping in general and about Ilya’s new OSM editor Every Door, in Geomob Podcast #132.
  • OSM Belgium has chosen Nicxon Piaso, from Papua New Guinea, as Mapper of the Month and introduced him in an interview.
  • Pieter Vander Vennet wrote about educational facilities, the current way of tagging them, and examined how to converge towards unified tagging of schools. Previous discussions on the subject and the difficulty in unifying even a simple country are reported by other contributors.

OpenStreetMap Foundation

  • Paul Norman pointed out the North American capacity issues with pyrene, the only US render server. It looks like Amazon may help with the server problem.
  • Simon Poole shared his insights about the limits and possibilities of reaching a EU-wide General Data Protection Regulations (GDPR)-compatible OSM world.

Local chapter news

  • There are still places available (de) > en at the OSM-FOSSGIS community meeting on the weekend of 1 to 3 July at the Linuxhotel in Essen. Travel is at your own expense; accommodation and meals will be provided by the the FOSSGIS Association, the German regional representation of OSM.


  • Anne-Karoline Distel shared a new video on the topic ‘Adding roads to hiking route relations’.
  • Daniel Capilla presented (es) > en a brief exposition of the possibilities offered by the OpenStreetMap data mining tool for those who wish to collaborate in the task of field verification of recycling containers in the municipality of Malaga, based on the key check_date and using the overpass turbo query wizard.

OSM research

  • Veniamin Veselovsky, Dipto Sarkar, Jennings Anderson and Robert Soden published a scientific paper about the development of an automated technique for identifying corporate mapping in OpenStreetMap.


  • Christoph Hormann published the third and fourth parts of a series about the depiction of trees in maps.
  • Holocrypto provides OSM Planet, Europe and Netherlands vectorial MBTiles for personal or educational use. The MBtiles packages are updated regularly.
  • Neue Züricher Zeitung is publishing an OSM-based daily updated interactive map of developments in the Ukraine war.


  • Grab launched GrabMaps, which aims to tap into the US$1 billion map and location-based services market in Southeast Asia. Grab still uses OpenStreetMap as its map base.

Did you know …

  • flipcoords, OpenCage’s new tool for reformatting coordinates to and from lat/lng to lng/lat or into named parameters?

Other “geo” things

  • [1] You might think the whole world knows about OpenStreetMap, and then you read this light-bulb moment (aha moment) from Chaz Hutton on Twitter. ‘Shout out to Ed Freyfogle for getting me onto it’, Chaz comments on his new insight.
  • Without words
  • The European Space Agency has released (fr) > en a three dimensional map of the Milky Way, including nearly two billion stars. It took ten years for the Gaia satellite, 1.5 million kilometres away from Earth, to collect the data and the mission will continue until 2025.
  • About a hundred people were rescued (fr) > en during a school trip this week in Kleinwalsertal, Austria. The teachers were apparently misguided by false information on the internet, leading the group onto the Heuberggrat path without warning them about its sheer difficulty.
  • As TechCrunch reported, Russian tech giant Yandex has removed national borders from its map apps.
