Copernicus DEM, binalar, altyapı ve bitki örtüsü dahil olmak üzere Dünya yüzeyini temsil eden bir Dijital Yüzey Modelidir (DSM).
Bu DEM, WorldDEM&trade adlı düzenlenmiş bir DSM'den elde edilmiştir. Yani su kütlelerinin düzleştirilmesi ve nehirlerin tutarlı akışı dahil edilmiştir. Kıyı şeritleri ve kıyı çizgileri, havaalanları gibi özel özellikler ve olası olmayan arazi yapılarının düzenlenmesi de yapılmıştır.
WorldDEM ürünü, Alman Devletinin (Alman Havacılık ve Uzay Merkezi (DLR) tarafından temsil edilir) ve Airbus Defence and Space'in Kamu-Özel Sektör Ortaklığı tarafından finanse edilen TanDEM-X Misyonu sırasında elde edilen radar uydu verilerine dayanmaktadır. Daha fazla ayrıntıyı veri kümesi belgelerinde bulabilirsiniz.
Earth Engine öğesi, DGED dosyalarından alındı.
