Hello, I find this Alti3D layer could be quite useful mapping path under tree cover or in remote areas. Exemple : https://map.geo.admin.ch/mobile.html?lang=en&topic=ech&bgLayer=ch.sw...
However it is not clear to me if this can be used for OSM mapping. https://www.geocat.ch/geonetwork/srv/eng/md.viewer#/full_view/1964cc81-5298-...
Any advice appreciated. Regards, Yves
