REMA version 4.1 DSM strips are a 13-year time series of elevation data derived from satellite imagery using photogrammetric methods.20092021Antarctica-180180-88-56Digital Elevation ModelDataset downloads, description, and documentation can be found at https://www.pgc.umn.edu/data/rema/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 Maxar satellite imagery, including data from WorldView-1, WorldView-2, and WorldView-3, and a small number from GeoEye-1.See PGC Acknowledgement Policy at https://www.pgc.umn.edu/guides/user-services/acknowledgement-policy/This dataset is made available under a Creative Commons CC4 license with the following additional/modified terms and conditions:Arcticdem, EarthDEM
