The aim of TessaDEM is to provide an elevation database representing the Earth terrain by combining 30-meter spatial resolution (Copernicus DEM, NASADEM) with absolute bias, stripe noise, speckle noise and tree height bias removal (MERIT DEM).
To achieve this, elevation readings were merged and adjusted according to several factors such as tree height, urbanization and water presence (Forest Height, World Settlement Footprint, Global Surface Water).
