Remote sensing at ITC-irst - MPA group
SRTM Shutte Radar Topography Mission
Software used: GRASS 6, GDAL and Povray
SRTM90 and VMAP0: Lago di Garda, Italia.
SRTM90 and LANDSAT-7: Val d'Aosta, Italia. View to North-West, to Monte Bianco (any camera
position can be rendered).
Data access
-
The official SRTM V1 data (original degree tiles)
Oct 2005: SRTM V2 data (original degree tiles)
-
SRTM V1 patched to larger WRS2 tiles
(Landsat scheme) and reprocessed to GeoTIFF
You are invited to use our scripts for SRTM data processing:
srtm_generate_hdr.sh: general shell script to make GeoTIFF from original SRTM90 files (reads the hgt.zip file and generated a BIL file with header). Requires GDAL tools to be installed.
r.in.srtm: GRASS script to import original SRTM files. To be used in Lat/Long LOCATIONS (WGS84, to be precise EGM96) - integrated into GRASS 6.0 (or later)!
Holes in the SRTM data can be closed within GRASS with r.fillnulls (uses splines, see reference below).
