Itยดs been a fun and insightful week at the #FOSSGIS2026 in Gรถttingen. See you again next year... in Heidelberg!

Thank you @FOSSGISeV, @osgeo and @unigoettingen for organizing such a huge and successful meetup of the DACH free and #opensource #GIS community.

Here are the session recordings, in case you missed any: https://media.ccc.de/b/conferences/geo/fossgis2026

We are now looking forward to being the local host of the FOSSGIS conference 2027 and welcoming the community at Heidelberg University.

A new study analyzed over 15 years of @openstreetmap research, showing collaboration networks and research trends. An interesting reading for the #OSM community and all #VGI researchers: https://arxiv.org/pdf/2601.09338

Weยดre proud that Heidelberg University is at the center of OSM research and our Scientific Director Alexander Zipf is the most prolific author in the field!

@hdvalentin hast du ein gutes Beispiel?

@richlv @heigit

One easy approach to approximate the actual level crossings could be to count all highways that have a node with the tag railway=level_crossing as a node. In overpass a request can look like that for Latvia: https://overpass-turbo.eu/s/1YnB

overpass turbo

A web based data mining tool for OpenStreetMap which runs any kind of Overpass API query and shows the results on an interactive map.

ohsome - dashboard

@richlv @LSM_Eng_rss @heigit Getting counts for all nodes with railway=level_crossing is quite easily possible in OSM. You can use the ohsome dashboard for this (might take a bit to calculate with so many countries). The bigger challenge is that a level crossing in railway terms is not the same as railway=level_crossing in OSM. A level crossing is normally counted once for all tracks it is crossing at the same time while in OSM you have one mapped node for every track a highway intersects.

February 22: Official Launch of the Sketch Map Tool! ๐ŸŽ‰

The Sketch Map Tool is an easy-to-use, open-source and free-of-charge tool which facilitates community mapping. You can use it to collect local spatial knowledge with pen and paper with an OpenStreetMap in the background. With the Sketch Map Tool, you can easily create a base map for your mapping.

Admittedly, these days #mastodons have a very special place in our hearts๐Ÿ˜‰ ๐Ÿฅฐ, so this new research really speaks to us! The oldest #DNA ever recovered, from permafrost in Greenland, has revealed that the elephant-like creatures roamed northern #Greenland 2 million years ago. Now a barren polar desert, the area apparently used to be a lush landscape of trees & home to a diverse flora & fauna. ๐Ÿค— *Go mastodons, go!* ๐Ÿ˜ ๐Ÿ˜‰ https://nature.com/articles/d41586-022-04377-x
