## 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.
