Arctic DEM v1.0

ArcticDEM is an NGA-NSF public-private initiative to automatically produce a high-resolution, high quality, digital surface model (DSM) of the Arctic using optical stereo imagery, high-performance computing, and open source photogrammetry software. The current ArcticDEM release contains version v1.0 of Alaska (except for Southeast Alaska).

ArcticDEM data is generated by applying stereo auto-correlation techniques to overlapping pairs of high-resolution optical satellite images. It is constructed from in-track, high-resolution (~0.5 meter) imagery acquired by the DigitalGlobe constellation of optical imaging satellites and licensed through the NGA NextView contact. The majority of ArcticDEM data was generated from the panchromatic bands of the Worldview-1, Worldview-2, and Worldview-3 satellites. A small percentage of data was also generated from the GeoEye-1 satellite sensor.

DEM strips can be downloaded from the ArcticDEM web page provided below. Arctic DEM is also provided as a webservice and Arcgis online item. See links below for further information.
