- Digital Elevation Terrain Model (DEM) - NASA Earthdata
NASA's data for digital elevation models (DEM) comes from airborne and space-based sources and are useful for analyzing a majority of Earth's terrain
- 到底什么是DEM？如何获取该数据？ - 知乎
DEM，Digital Elevation Model，DEM，数字高程模型，是描述地表起伏形态特征的空间数据模型，目前可以免费下载到的全球DEM数据主要有SRTM、HGTNASA、AW3D30、TanDEM-X DEM等。
- 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
- NASADEM: Creating a New NASA Digital Elevation Model and Associated . . .
NASADEM is a significant improvement over the available three-arcsecond SRTM DEM primarily because it will provide a global DEM and associated products at one-arcsecond spacing
- 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)
- 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。
- New Version of the ASTER GDEM - NASA Earthdata
Version 3 of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) is now available from NASA’s Land Processes Distributed Active Archive Center (LP DAAC) The ASTER GDEM covers land surfaces between 83°N and 83°S, and was produced through automated processing of 2 3 million scenes from the ASTER archive
