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:
To import TOPEX/SRTM30 PLUS data, use r.in.bin.
