DESCRIPTION

       r.in.srtm  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):
       http://dds.cr.usgs.gov/srtm/

NOTES

       SRTM tiles are of 1 degree by 1 degree size. The SRTM filename  contains  the  coordinates
       which  refer  to the center 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:
       d.grid size=1
        To import TOPEX/SRTM30 PLUS data, use r.in.bin.
