Product Sheet

About NakedEarth – the unique terrain model

Product Information

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.
Measured from space AW3D30 presents the heights at the tops of trees, buildings and other "first surface" features. NakedEarth estimates the elevations of Earth's terrain as if these features were removed.
