DESCRIPTION
r.in.srtm imports SRTM HGT files into GRASS. SRTM Version 1 and im-
proved 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:
https://e4ftl01.cr.usgs.gov/MEASURES/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 by d.grid:
d.grid size=1
To import TOPEX/SRTM30 PLUS data, use r.in.bin.
