ASTER Digital Elevation Model V004
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aster/ast14dem.004
Description
The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (AST14DEM) product is generated using bands 3N (nadir-viewing) and 3B (backward-viewing) of an ASTER Level 1A image acquired by the Visible and Near Infrared (VNIR) sensor. The VNIR subsystem includes two independent telescope assemblies that facilitate the generation of stereoscopic data.
The band 3 stereo pair is acquired in the spectral range of 0.78 and 0.86 microns with a base-to-height ratio of 0.6 and an intersection angle of 27.7 degrees. There is a time lag of approximately one minute between the acquisition of the nadir and backward images. For a better understanding, refer to the diagram depicting the along-track imaging geometry diagram of the ASTER VNIR nadir and backward-viewing sensors.

Known Issues
* Data acquisition gap: On November 28, 2024, one of Terra's power-transmitting shunt units failed. As a result, there was insufficient power to maintain functionality of the ASTER instrument. ASTER resumed acquisitions for the VNIR bands on January 18, 2025.
Users should note the data gap in ASTER acquisitions from November 28, 2024, through January 16, 2025, for VNIR observations.
