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.
