Category FAQ
Category FAQ
Which free DEM should I start with for global work?
OpenTopography and Copernicus DEM are the most practical starting points because they are global, well known, and easy to explain in search-friendly content.
Do these DEM pages give me direct downloads or official portals?
Both. Each page keeps an official source URL plus the most useful direct or API-style download path when one is available.
