University of Minnesota The Reference Elevation Model of Antarctica (REMA)
High resolution, time-stamped Digital Surface Model (DSM) of Antarctica at 8-meter spatial resolution.
REMA is constructed from hundreds of thousands of individual stereoscopic Digital Elevation Models (DEM) extracted from pairs of submeter (0.32 to 0.5 m) resolution DigitalGlobe satellite imagery, including data from WorldView-1, WorldView-2, and WorldView-3, and a small number from GeoEye-1, acquired between 2009 and 2017, with most collected in 2015 and 2016, over the austral summer seasons (mostly December to March).
