Correct. For things like that I'd also use GlobalMapper and QGIS that can handle such data amounts with ease.

Not true. Meanwhile there are many sources out there derived from LIDAR that have a much better resolution.
See e.g. https://www.data.gv.at/katalog/dataset/l...irolgelnde ,

Hello SaschaT ! any chance you can provide a tutorial to do this in QGIS ? I have made a hudge search over the net and didn't find a solution...some exist but are using plugins that do not exist anymore.
I fact I think the real resolution is not a problem : when you look the Opentopomap they have done probably an "interpolation" map that gives the feeling it's very detailled ( about elevation I mean ) ... and the zone I would like is for sure not in public domain with a 1m detail like in us maps...so the idea is to do a "simulation map" from the exiting one. The one I get for now is quite good for what I would like to do but I am sure I can get much better if I can collect the necessary 1 000 000 points by km2, then glue the 529 needed tiles all together to make the .R16 file I need.
