Service Description: Dynamic Image Service covering data for Antarctica Region at 8m resolution. The Reference Elevation Model of Antarctica (REMA) built by Polar GeoSpatial Center (PGC) provides high resolution elevation data. REMA is generated from Digital Globe Imagery acquired between 2009 to 2017. Each Pixel is attributed with a date at which it was captured. This service provides access to elevation values for use in analysis with server-side functions for slope, aspect, hillshade and contour. For more information on this service, including the terms of use, visit us online at AntarcticDEM.
