DEM
ALOS World 3D 30 m (AW3D30)
ALOS Global Digital Surface Model. 30 m surface model from PRISM optical stereo.
A digital surface model resampled from JAXA's 5 m AW3D product, derived from the PRISM stereo camera on ALOS. It often beats SRTM in steep terrain; like all optical DEMs it has small voids under persistent cloud and snow.
