Global Digital Terrain Model 10m
LuxCarta utilizes readily available digital surface models, along with its imagery mosaic and land use/land cover (LULC), to generate a global digital terrain model (DTM) at 10m. DTMs are essential for accurately representing the Earth's surface, enabling precise analysis of topography, flood risk assessment, urban planning and environmental management.
The LuxCarta DTM is produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.
