The Global Multi-Resolution Topography (GMRT) synthesis is a compilation of multibeam sonar data collected by scientists and institutions worldwide, edited and merged into a single continuously updated compilation of high-resolution seafloor topography.

The synthesis began in 1992 as the Ridge Multibeam Synthesis (RMBS), and now includes other bathymetry from throughout the global and coastal oceans.

全球海洋的测量已经融为一个大的数据体了。

GMRT is maintained as a multi-resolution gridded digital elevation model that includes seafloor bathymetry to ~100 m spatial resolution (to ~50 m in some coastal regions).
是一个多分辨率的网格化的数字高程模型包括海底测深数据高达100m的空间分辨率，在一些沿岸区域高达50m。

Multibeam data are merged with lower-resolution compilations including the General Bathymetric Chart of the Oceans ,
多光束数据也和低分辨率的融合起来。

the International Bathymetric Chart of the Arctic Ocean 、and the SCAR Subglacial Topographic Model of the Antarctic (. Also included are elevation data from NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer global DEM which provide 30 m resolution of terrestrial areas throughout the world, and the USGS National Elevation Dataset providing up to 10 m resolution in some areas of the US.

所以分辨率对研究的力度有一定影响。.
