@infeeeee @Munkisquisher Bing providing access to their imagery goes back when Steve Coast worked for them.

@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.
