I am working on a project cataloguing a collection of ~200 sites around the world, at varying scales. For each site, I would like to extract a DEM from the Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) or any other global DEM with 30m or higher resolution.

Where I can download the full ASTGTM all at once? So far, I've only been able to find links to download subsets of this dataset.

Alternatively, if anyone knows of a better source for global elevation data or a better method for getting high-resolution elevation data for sites around the world from a single source, I am all ears!

Thanks!

Hi, 

Try to download Alos Palsar 12.5 (DEM)  resolution.
