Hi all, You already implemented high resolution hill shading in Switzerland. There is something similar in France with the SCAN25TOUR_PYR-JPEG_WLD_WM layer from https://wxs.ign.fr/YOUR_KEY/geoportail/r/wms?SERVICE=WMS? The state of the art DEM from IGN is now RGE ALTI® 1M. Documentation here: https://geoservices.ign.fr/rgealti and https://geoservices.ign.fr/documentation/donnees/alti/rgealti

Thank you. I will put it to my long TODO priority queue.

Used RGE ALTI® 5M.

Note that RGE ALTI® 1M would require much more volume to download and process but would bring no remarkable improvements as it often contains only upscaled data from the lower resolution.
