ArcticDEM is a digital surface model (DSM) that portrays first-return
elevation values that include 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.
Mosaicked DEM files are compiled from the best quality strip DEM files
which have been blended and feathered to reduce void areas and edge-matching
artifacts. Filtered IceSAT altimetry data has been applied to the raster
files to improve absolute accuracy.
