The GRASS GIS software - GIS Seminar
Introduction to GRASS GIS and QGIS for newcomers
Course duration: 6 hours course with practical
examples based on GRASS 6 and
QGIS 0.8 using the
Spearfish 6.0 dataset.

Further ideas for Spearfish related GIS tasks in GRASS/QGIS
- Overlay and compare the spatial precision of the road map and a LANDSAT satellite image (get from:
LANDSAT-7 scene reprojected for Spearfish location). Why don't they match and which map is more precise?
- Take the included DEM 'elevation.10m' and generate new maps from that such as aspect, slope (in degree), curvatures, watersheds, streams (vectorize them and compare to the existing streams map), topographic index, flow lines, direct/diffuse/reflected radiation for a certain day etc.
- Visualize with nviz the elevation model with a RGB LANDSAT color composite draped above
