.SH DESCRIPTION
\fIr.in.srtm\fR imports SRTM hgt files into GRASS.
SRTM Version 1 and improved Version 2 data sets can be downloaded from
NASA at this site:
.br
http://dds.cr.usgs.gov/srtm/
.PP
Gap\-filled SRTM Version 3 data can be downloaded from USGS at this site:

.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:
.br
.nf
\fC
d.grid size=1
\fR
.fi
To import TOPEX/SRTM30 PLUS data, use \fIr.in.bin\fR.
