Quality The Australian Antarctic Division (AAD) DEM is based on a DEM produced by Intermap Technologies from Stereoscopic RADARSAT images acquired in March and April of 1997. Heights in the AAD DEM were referenced to the WGS-84 ellipsoid. The AAD DEM was produced by subtracting 40 metres from all vertices in the Intermap DEM. 40 metres is the average geoid-ellipsoid separation, modelled from EGM-96, in ... View entire text
