El DEM de Copernicus es un modelo digital de superficie (DSM) que representa la superficie de la Tierra, incluidos los edificios, la infraestructura y la vegetación.
Este MDT se deriva de un MDV editado llamado WorldDEM&trade, es decir, se incluyó el aplanamiento de las masas de agua y el flujo constante de los ríos. También se aplicó la edición de costas y litorales, y de elementos especiales, como aeropuertos y estructuras de terreno inverosímiles.
El producto WorldDEM se basa en los datos de satélite radar adquiridos durante la misión TanDEM-X, que se financia a través de una asociación público-privada entre el Estado alemán, representado por el Centro Aeroespacial Alemán (DLR), y Airbus Defence and Space. En la documentación del conjunto de datos, se incluyen más detalles.
Se incorporó el recurso de Earth Engine desde los archivos de DGED.
