Benefits of using NakedEarth

About NakedEarth – the unique terrain model

NakedEarth is produced based on the global, 30m posting Digital Surface Model AW3D30 (released by Japan Aerospace Exploration Agency, ©JAXA) and ancillary data (forest, settlement, water masks) to remove man-made construction and vegetation heights. It was processed with Novlum’s proprietary DTM generation system, a fully-automated, high sophisticated processor which preserves terrain features (breaklines, ridges and depth lines) while removing building areas and forests. NakedEarth covers same areas as AW3D30.
