Create a DEM using Sentinel-1 Data - NASA Earthdata This recipe from NASA's Alaska Satellite Facility guides you through creating a Digital Elevation Model (DEM) from two Sentinel-1 SLC scenes Follow the steps: create an interferogram, perform phase unwrapping, and generate the DEM
ASTER Global Digital Elevation Model V003 | NASA Earthdata The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator)
New in CSDA: High Resolution Digital Elevation Models High-resolution Digital Elevation Models (DEM) for non-polar regions at two-meter spatial resolution are now available through NASA’s Commercial SmallSat Data Acquisition (CSDA) program
Access to High-Resolution DEMs | NASA Earthdata NASA's Commercial Satellite Data Acquisition program enables this Satellite Needs Working Group solution by providing access to two 2 0 m Digital Elevation Model (DEM) products
我想下载且只想下载某个省份的DEM数据，该如何下载? - 知乎 插值算法来自于Reuter et al （2007） 这里我以SRTMDEM 90M 分辨率原始高程数据下载为例，选择以行政区来进行数据下载 然后点击检索，可以看到江西省需要五副DEM影像才能完整覆盖，那么把列表显示的五个数据下载下来就好了。
