Operation ID: getGlobalDem
Auth: api_key
Description

Access global topographic datasets including SRTM GL3 (Global 90m), GL1 (Global 30m), ALOS World 3D, SRTM15+ V2.1, GEBCO IceTopo, and GEBCO SubIceTopo. Note: Requests are limited to 500,000,000 km² for GEDI L3, 125,000,000 km² for SRTM15+ V2.1, GEBCO IceTopo, and GEBCOSubIceTopo, 4,050,000 km² for SRTM GL3, COP90 and 450,000 km² for all other data. Requires API key.
