ASTER gathers data in 14 spectral bands: 3 visible and 11 in the infrared region of the electromagnetic spectrum. It has a nadir and backward facing Band 3 which gives it the unique ability to create digital elevation models based on stereo images.
SRTM based on the older Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR), previously used on the Shuttle in 1994.
