btw, the Swiss Federal Office of Topography (Swisstopo) has lots of cool open geo data: https://www.swisstopo.admin.ch/en/maps

One of the (IMHO) most interesting datasets is the extremely detailed digital elevation model / DSM (swissSURFACE3D):
https://www.swisstopo.admin.ch/en/height-model-swisssurface3...
Lidar scanned terrain model, with a grid size of 0.5m and vertical resolution of ~10cm. Available as a tiled raster or the "raw" classified point cloud (ground, vegetation, water, ...).

Demo (Shaded Relief based on that surface model. Those stair step patterns are not artifacts, but the natural terracing of vineyards):
