I'll probably do if there are once Opendata Lidar sources of this German province (Sachsen). Right now I'm afraid there's no such data available for free use.

No free data for Sachsen, that's sad, I'm sometimes @ Erzgebirge.

Oh what a difference, I reset the height levels in Locus pro for some tracks and the Höhenmeter up/down (elevation gain ?) values went down e.g. from 9xx to 500 something...  :o But I cannot say for sure if I really used the old SRTM data or GPS data pulled by my phone. However, what a big difference. It's overall like 30-40% difference.

Is it possible to use the 20/50m models with Locus?

i'm afraid not. But the 1"  models (.hgt files) are about as precise as the 20m models

I spent many hours and weeks to collect and edit the source data for creating a DTM for the whole country of Italy. Most of the Italian regions provide more or less high quality data. For those who don't, I used 1" SRTM data.
Now the project is finished and available here:

@sonny ...you're awesome!  We'll use it for LoMaps as your previous datasets. Thank you

There's been a problem in the Northwest of the Italian files. Please download the corrected ones here:
