DESCRIPTION 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):


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 itentify a tile name, a grid can be easily visualized in the GRASS monitor:
d.grid size=1
