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: 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.
