2024年7月26日 · The ETOPO Global Relief Model integrates topography, bathymetry, and shoreline data from regional and global datasets to enable comprehensive, high resolution renderings of geophysical characteristics of the earth’s surface. The model is designed to support tsunami forecasting, modeling, and warning, as well as ocean circulation modeling and ...
Global relief model - Wikipedia
A global relief model, sometimes also denoted as global topography model or composite model, combines digital elevation model (DEM) data over land with digital bathymetry model (DBM) data over water-covered areas (oceans, lakes) to describe Earth's relief. A relief model thus shows how Earth's surface would look like in the absence of water or ...
Topography and Digital Terrain Data | NCEI - National Oceanic and ...
NCEI's ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions.
11.4 earth_relief: 全球地形起伏数据 — GMT中文手册
GMT提供了从15弧秒到60弧分的多种不同精度的全球地形起伏网格数据供用户使用。 这些数据保存在GMT的 FTP服务器 上（国内镜像）。 当用户第一次使用某个精度的地形起伏数据时，GMT会自动从服务器上下载该数据文件，并保存到GMT的缓存文件夹下（由 DIR_CACHE 控制，默认为 ~/.gmt/server 目录），然后再读取该文件。 以后再使用该数据时，GMT会自动从缓存文件夹下读取该数据文件，而无需再次从服务器下载。 建议用户自行手动下载所有的地形起伏数据并将 …
