Description
ArcticDEM is a National Geospatial-Intelligence Agency (NGA) and National Science Foundation (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. It includes vegetation, tree canopy, buildings, and other man-made surface features. The 2m asset is a collection of strips rather than a single mosaic due to projection differences between strips.
Strip DEM files correspond to the overlapping area of the input stereopair image swaths as they are collected by DigitalGlobe's constellation of polar-orbiting satellites. Strip DEM dimensions will vary according to the satellite sensor that acquired the images and the off-nadir angle of collection. Most strips are between 16km and 18km in width, and 110km and 120km in length.
