Raster support in GRASS GIS

The GRASS Development Team and members of the user community have collected numerous screenshots on these pages.

For details, see the raster map and 3D raster data (voxel) processing guides.

GRASS 6.3

Catchment basins and water courses for Spearfish, South Dakota. Generated using commands given in the r.watershed help page

Elevation, slope, land cover, and training areas example for Spearfish, South Dakota. Generated with ps.map using the commands found in this script. Commands to create a similar image with the display modules can be found in the d.out.file help page.

GRASS 6.1

Void filling in SRTM DEM data with splines (r.fillnulls). See related article in GRASS Newsletter #3, June 2005
screenshot: M. Neteler

Accumulated daily global radiation for 1 year at Trento (Italy) without shadow and cloud correction (r.sun). The valleys are at 200-600m elevation while the mountains reach 2100m.
SRTM V2 data, screenshot: M. Neteler

Accumulated daily global radiation for 1 year at Trento (Italy) with shadow correction (r.sun). The valleys are at 200-600m elevation while the mountains reach 2100m. This map is much closer to reality, optional cloud correction was not applied. The color table is identical to above uncorrected map.
