Alaska Digital Surface Models (DSMs) - USGS National Map 3DEP Downloadable Data Collection
These data are Digital Surface Models (DSM) derived from interferometric synthetic
aperture radar (ifsar) data. A DSM is a 3 dimensional representation of surface elevations
in an area, including elevations of man-made structures and vegetation. The USGS performs
minimal quality assurance and no reprocessing of the DSM data. USGS distributes the DSM data
as received from the contractors, partners or contributing entities.
