DEM Copernicus adalah Model Permukaan Digital (DSM) yang merepresentasikan
permukaan Bumi termasuk bangunan, infrastruktur, dan vegetasi.
DEM ini berasal dari DSM yang diedit bernama WorldDEM&trade, yaitu perataan badan air dan aliran sungai yang konsisten telah disertakan. Pengeditan garis pantai dan pesisir, fitur khusus seperti bandara, dan struktur medan yang tidak masuk akal juga telah diterapkan.
Produk WorldDEM didasarkan pada data satelit radar yang diperoleh selama Misi TanDEM-X, yang didanai oleh Kemitraan Publik-Swasta antara Negara Jerman, yang diwakili oleh Pusat Dirgantara Jerman (DLR) dan Airbus Defence and Space. Detail selengkapnya tersedia dalam dokumentasi set data.
Aset Earth Engine telah di-ingest dari file DGED.
