Using the JOSM Conflation plugin [1] | © JOSM – watmildon | map data © OpenStreetMap contributors


  • SherbetS documented the HIFLD dataset with a walkthrough on how to adjust this kind of file to match OSM tagging guidelines. HIFLD is a large corpus of public domain licensed geospatial information about infrastructure around the United States. Matt Whilden used this and the JOSM Conflation plugin to detect unmapped items.
  • [1] Matt Whilden showed how to add 1500 addresses to OSM in 10 minutes using the JOSM Conflation plugin.
  • Anton Khorev was happily surprised to find out that iD also worked on his mobile phone. In order to optimise the experience, he advises directly opening the respective frame (https://www.openstreetmap.org/id instead of the usual https://www.openstreetmap.org/edit?editor=id) which spares you losing space to the navigation bar.
  • User publicerination wrote about replacing quantity=* tags on pitches in the San Francisco Bay area.
  • The ‘Markers subject refinement’ proposal is open for comments. It proposes the introduction of a subset of marker=* with subject=* to allow a clearer indication of what a utility marker is referring to.
  • The ‘Public Transport: Auditory Information’ proposal is open for voting until Tuesday 2 May. The proposal aims to establish multiple tags to gather different types of auditory information that may be provided at a public transport stop and/or platform.


  • Anne-Karoline Distel wrote about how the OpenStreetMap community actively responded to the idea of mapping milk churn stands (we reported earlier). In particular, the number of these objects mapped in Finland significantly increased after the collaboration of users houtari and Jyrki Kokko – Finnish milk churn stands are very much a thing [fi]►. Discussion is ongoing about creating a dedicated preset for the iD editor, to make it easier for beginners to map milk churn stands.
  • In episode 177 of the Geomob Podcast we hear from the maker of ‘The Melbourne Map’. Steven Feldman interviewed self-proclaimed ‘accidental map maker’ Melinda Clarke.
  • Growebis is looking for help in mapping buildings in Montreal.


  • Knooppuntnet is an OSM-based website that documents the node networks that are common in the Netherlands and Belgium (routes for walking, cycling, horse riding and more). Check out the homepage or have a look at the demo.

Open Data

  • OpenStreetMap US shared its insights on the way ahead to benefit from Public Domain and OSM data, taking into account the different licences that apply to them.


  • Starting with version 3.7, GDAL’s OpenStreetMap XML and PBF formats driver has a new setting to format ‘all_tags’ and ‘other_tags’ as JSON instead of hstore. In particular, users of ogr2ogr that redistribute OpenStreetMap can enable the feature, so that the recipients of the data do not need to depend on PostgreSQL or GDAL to parse the column.
  • Stefan Keller [recommended>>>, a kind of ‘Street View’ for cyclists! It is open source and uses OSM data.


  • Recently darkonus decided to experiment with GPT-4, a state-of-the-art language model by OpenAI, to see if it is possible to come up with a fresh approach to visualising the history of OSM data. They shared their initial attempts, examples of the traditional OSM Deep History table, and the new visualisation created with GPT-4’s assistance.
  • taginfo is a long-standing OSM project that analyses OpenStreetMap tags. The developer Jochen Topf has modernised the website’s JavaScript and CSS to improve its performance and compatibility with modern web technologies. While the site’s appearance and functionality remain largely unchanged, the update paves the way for better support on smaller screens, such as mobile phones. Despite some minor issues introduced during the update, Jochen is satisfied with the current state of the website and plans to focus on content improvements in future iterations.

Did you know …

  • Notes Map ? It tries to guess what an OSM map note is about by using keywords and hashtags. To load notes, zoom in, click on Notes dazu Laden.
  • … the OSM ↔ Wikidata matcher, which was recently presented by developer Edward Betts at the FOSS-North 2023 conference?
  • … there is a modified version of StreetComplete called SCEE? It is aimed at experienced OSM contributors who desire advanced editing capabilities in StreetComplete and is available on F-Droid.

Other “geo” things

  • Swisstopo announced that they will be producing a series of SoundCloud podcasts ( only). The first episode covers the development of the cartography of glaciers, lakes, and other water and wetland features. The second episode deals with the stages of the digitalisation of the main topographic maps series.
