Dear listers,
STRM 90-m DEMs for Africa are now available at this FTP-thread:
ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/Africa
30-m SRTM DEMs are now available only for USA, future prospects
on their public distribution for other territories is not clear.
Free SRTM DEMs are interesting, in part, in that one may use these
raw data to decode forest boundaries (SRTM elevations are 2-5m
larger in forests), roads, tree boundings of agricultural fields, and
so on. Their essential disadvantage is that elevations are rounded
to whole number of meters. Nevertheless, these are the only
high-resolution global DEMs.

Subject : Africa SRTM release
NASA and NIMA have released the Shuttle Radar Topography Mission
Digital Elevation Model (DEM) for Africa and the Middle East. These
preliminary elevation data are posted at 3 arc-sec and are in the
same format as previous releases for North and South America and
Eurasia. They may be accessed by ftp at:
edcftp.cr.usgs.gov/pub/data/srtm/Africa and will soon be on the USGS
Seamless Server site. Documentation is also available at the
ftp site.
The last data release including Australia, New Zealand, and other
islands, is planned for June, 2004.
We also note that a public bulletin board for exchange of information
between users of SRTM data is now available. The bulletin board may
be accessed at:
http://pub6.dream-tools.net/tools/messages.mv?index%20srtm2004forum
Please note that this forum was set up to allow anyone to discuss
publicly information regarding the Shuttle Radar Topography Mission.
The site is independent from the JPL SRTM web site and is neither
funded nor supported by JPL, NASA, NGA, nor any related partners.
