코페르니쿠스 DEM은 건물, 인프라, 식물을 포함한 지구 표면을 나타내는 디지털 표면 모델 (DSM)입니다.
이 DEM은 WorldDEM&trade라는 수정된 DSM에서 파생됩니다. 즉, 수역의 평탄화와 일관된 강의 흐름이 포함되어 있습니다. 해안선과 해안, 공항과 같은 특수 지형지물, 불가능한 지형 구조도 수정되었습니다.
WorldDEM 제품은 독일 항공우주센터 (DLR)와 Airbus Defence and Space가 대표하는 독일 정부 간의 공공-민간 파트너십에 의해 자금을 지원받는 TanDEM-X 미션 중에 획득한 레이더 위성 데이터를 기반으로 합니다. 자세한 내용은 데이터 세트 문서를 참고하세요.
Earth Engine 애셋이 DGED 파일에서 수집되었습니다.

Editing of\nshore- and coastlines, special features such as airports and implausible\nterrain structures has also been applied.\n\nThe WorldDEM product is based on the radar satellite data acquired during\nthe TanDEM-X Mission, which is funded by a Public Private Partnership\nbetween the German State, represented by the German Aerospace Centre (DLR)\nand Airbus Defence and Space. More details are available in the dataset\n[documentation](https://spacedata.copernicus.eu/documents/20123/121239/GEO1988-CopernicusDEM-SPE-002_ProductHandbook_I4.0.pdf).\n\nEarth Engine asset has been ingested from the DGED files.\n| **Note:** See the code example for the recommended way of computing slope. Unlike most DEMs in Earth Engine, this is an image collection due to multiple resolutions of source files that make it impossible to mosaic them into a single asset, so the slope computations need a reprojection.\n\n### Bands\n\n\n**Pixel Size**\n\n30 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|-------|-----|-----|------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `DEM` | | | meters | Digital Surface Model |\n| `EDM` | 0 | 13 | meters | The Edit Data Mask indicates all DEM pixels that were modified during the terrain and hydro editing process. |\n| `FLM` | 0 | 101 | meters | The Filling Mask is created primarily during the terrain editing process. |\n| `HEM` | | | meters | 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. |\n| `WBM` | 0 | 3 | meters | The Water Body Mask shows all DEM pixels which are classified as water and edited according to the categories Ocean, Lake or River. |\n\n**EDM Class Table**\n\n| Value | Color | Description |\n|-------|-------|------------------------------------------------|\n| 0 | None | Void (no data) |\n| 1 | None | Not edited |\n| 2 | None | Infill of external elevation data |\n| 3 | None | Interpolated pixels |\n| 4 | None | Smoothed pixels |\n| 5 | None | Airport editing |\n| 6 | None | Raised negative elevation pixels |\n| 7 | None | Flattened pixels |\n| 8 | None | Ocean pixels |\n| 9 | None | Lake pixels |\n| 10 | None | River pixels |\n| 11 | None | Shoreline pixels |\n| 12 | None | Morphed pixels (series of pixels manually set) |\n| 13 | None | Shifted pixels |\n\n**FLM Class Table**\n\n| Value | Color | Description |\n|-------|-------|--------------------------------|\n| 0 | None | Void (no data) |\n| 1 | None | Edited (except filled pixels) |\n| 2 | None | Not edited / not filled |\n| 3 | None | ASTER |\n| 4 | None | SRTM90 |\n| 5 | None | SRTM30 |\n| 6 | None | GMTED2010 |\n| 7 | None | SRTM30plus |\n| 8 | None | TerraSAR-X Radargrammetric DEM |\n| 9 | None | AW3D30 |\n| 100 | None | Norway DEM |\n| 101 | None | DSM05 Spain |\n\n**WBM Class Table**\n\n| Value | Color | Description |\n|-------|-------|-------------|\n| 0 | None | No water |\n| 1 | None | Ocean |\n| 2 | None | Lake |\n| 3 | None | River |\n\n### Terms of Use\n\n**Terms of Use**\n\nThe GLO-30 dataset is available worldwide with a free license with the\nexception of two countries (Armenia and Azerbaijan).
