Description
The Copernicus DEM is a Digital Surface Model (DSM) which represents the surface of the Earth including buildings, infrastructure and vegetation. This DEM is derived from an edited DSM named WorldDEM&trade, i.e. flattening of water bodies and consistent flow of rivers has been included. Editing of shore- and coastlines, special features such as airports and implausible terrain structures has also been applied.
The WorldDEM product is based on the radar satellite data acquired during the TanDEM-X Mission, which is funded by a Public Private Partnership between the German State, represented by the German Aerospace Centre (DLR) and Airbus Defence and Space. More details are available in the dataset documentation.
Earth Engine asset has been ingested from the DGED files.

EDM |
0 | 13 | The Edit Data Mask indicates all DEM pixels that were modified during the terrain and hydro editing process. |
FLM |
0 | 101 | The Filling Mask is created primarily during the terrain editing process. |

The Height Error Mask represents the corresponding height error for each DEM pixel in the form of the standard deviation derived from the interferometric coherence and geometrical considerations. |

WBM |
0 | 3 | The Water Body Mask shows all DEM pixels which are classified as water and edited according to the categories Ocean, Lake or River. |
