SRTM data sets can be downloaded from NASA at this FTP site (Version 1 and the improved Version 2): .br http://dds.cr.usgs.gov/srtm/ .SH NOTES SRTM tiles are of 1 degree by 1 degree size. The SRTM filename contains the coordinates which refer to the \fBcenter\fR of the lower left pixel (e.g., N51E010: lower left cell center at 10E, 51N). To identify a tile name, a grid can be easily visualized in the GRASS monitor: \fC .DS .br d.grid size=1 .br .DE \fR To import TOPEX/SRTM30 PLUS data, use \fIr.in.bin\fR. .SH SEE ALSO \fI r.in.bin \fR .PP The Shuttle Radar Topography Mission homepage at NASA's JPL. .br The SRTM Web Forum .SH REFERENCES M.
