DESCRIPTION

       r.in.srtm imports SRTM hgt files into GRASS.  SRTM Version 1 and improved Version  2  data
       sets can be downloaded from NASA at this site:
       http://dds.cr.usgs.gov/srtm/

       Gap-filled SRTM Version 3 data can be downloaded from USGS at this site:
       http://e4ftl01.cr.usgs.gov/SRTM/SRTMGL3.003/2000.02.11/

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.
