Dear OpenStreetMap community,
I want to tell you, that I’ve created Digital Terrain Models (DTMs) of many European countries. These are based on precise Opendata LiDAR-elevation data of the country’s Geographical Institutes.
The improvements in accuracy, quality and fine details of these model’s compared to those of satellite-based datasets like SRTM, ASTER, ALOS, COPERNICUS are enormous. Especially in wooded areas, steep rocky terrain or narrow valleys.
Download and use are for free, although I appreciate a donation to support my work 
You can find all infos and download links on my website:
