@malte @qgis @qgisDE @openstreetmap IIRC @josmeditor https://josm.openstreetmap.de/ has support with a plugin, otherwise simply convert to GeoJSON and you can use JOSM and @vespucci_editor. Naturally you should check that you are permitted to use the DEM to contribute to OSM.

Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.

There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
Yes, JOSM has GeoJSON and OpenData plugins.
The technical side is only half of it though as the source has to meet the license requirements and there is a process to follow for imports:

Great! Thank you, I looked into JOSM befit but didn’t really now what to look for. (Until now I only used it for HOT tasks.)
I’m afraid you just stole a lot of time from me but made the map better 😬
