NASA SRTM 30 m (Global)
Shuttle Radar Topography Mission (SRTM). 30 meter digital elevation model.
The void-filled SRTM Global 1 arc-second product (SRTMGL1 v3), flown on the Space Shuttle Endeavour in February 2000. It remains the most widely used near-global DEM for watershed delineation, stream network extraction and hydrological model setup. Tiles are 1° × 1° and named by their south-west corner.
