[GRASS-user] Global Multi Resolution Topography dataset

[John A Stevenson]

I've just come across the Global Multi Resolution Topography dataset.  
It combines multibeam sonar with satellite bathymetry to produce a DEM 
of the oceans, and uses SRTM for the land.  Data can be downloaded at ~1 
arcsecond resolution (~90 m).

I've put links and more information on the wiki: 
http://grass.osgeo.org/wiki/Global_datasets#Global_Multi-Resolution_Topography_.28GMRT.29

There is a WMS server for the data but I haven't managed to use it 
successfully.  Instead, I downloaded tiles using wget, which I found 
very convenient.  I generally have mixed results with r.in.wms.

Cheers

John
