ArcticDEM (2m)

ArcticDEM is an NGA-NSF 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. ArcticDEM data is constructed from in-track and cross-track high-resolution (~0.4 meter) imagery acquired by the Maxar constellation of optical imaging satellites.
