Notes

The OGD terms list the accepted source references in German, French, Italian and English (for example "Federal Office of Topography swisstopo" or "©swisstopo"); use one of them. Some products, including swissALTI Regio and swissEO, require different wording, so check each product's own documentation.
Data is a surface without vegetation and buildings. The 0.5 m grid is oversampled where the source density is too low.
Formats per the product page: Cloud Optimized GeoTIFF (LZW) and ASCII X,Y,Z; ESRI ASCII GRID on request. A 2 m tile is about 1 MB, a 0.5 m tile about 26 MB, full coverage 44 GB at 2 m.
Coordinate system is Swiss LV95 / LN02; reproject before importing into a game engine.
Excessive use of the geoservices may be throttled; download tiles rather than scraping services.
