- 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
- NASADEM Merged DEM Global 1 arc second V001 - Earthdata
Description The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for the archive and distribution of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Digital Elevation Model (DEM) version 1 (NASADEM_HGT) dataset, which provides global elevation data at 1 arc second spacing
- 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。 SRTM
- 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
Description 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)
- 请问如何在网站上下载免费的DEM数据？ - 知乎
到这里数据下载就完成啦！ 2 数据预处理（镶嵌和裁剪） 将下载下来的压缩包全部解压缩，在ArcGIS中加载出来，顺便将桂林市边界加进来，可以看见，DEM数据完全覆盖了桂林市，但是分幅之间有明显的的界线，一看就是个九宫格，这是我们需要对数据进行镶嵌。
- 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
- 海运中的滞期费 DEM 和滞留费 DET 分别是什么意思？ - 知乎
1、DEM（DEMURRAGE CHARGES）：滞期费 2、DET（Detention Charge）：拘留费 国贸程租业务中滞期费，就必然涉及买卖舍约。 法院认为滞期费是因租船人不能在合同规定的装卸时间内完成装卸货的违约行为而由租船人支付的损害赔偿。 在实务中，速遣费通常为滞期费的一半。
