.SH DESCRIPTION
\fIr.in.srtm\fR imports SRTM hgt files into GRASS.
SRTM data sets can be downloaded from NASA at this FTP site (Version 1 and the
improved Version 2):

.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

d.grid size=1

To import TOPEX/SRTM30 PLUS data, use \fIr.in.bin\fR.
