Resource of the Week: Seamless Shuttle Radar Topography Mission (SRTM) 3 Arc Second (90m)

This week's Map and Data Library geospatial data resource of the week is
NASA/NGA's Seamless Shuttle Radar Topography Mission (SRTM) 3 Arc Second
(90m) Digital Elevation Model. The data have been available to us for a
few years on an external hard drive but this is the first time we have
had enough server disk space to load the data for access on the web.
All files are downloadable and can be identified through an interactive
map index we built on GIS Cloud. The data record is here:

http://maps.library.utoronto.ca/cgi-bin/datainventory.pl?idnum=807&display=full

Please note that these data are also available here:
http://srtm.csi.cgiar.org/ but that this site is extremely slow and
difficult to use. Our site allows for quite an easy location of
datasets and download.

For more information on this resource, please see this PDF document:
