An example for vector processing using the basins raster created in the previous step: 1) convert the basins to vector areas with r.to.vect -v feature=area 2) load average elevation for each basin to the attribute table with v.rast.stats 3) assign the color table of the raster elevation using average elevation values to the basins vector with v.colors column=elev_mean raster=elevation.10m 4) display the vector using the colors in GRASSRGB BTW, there is no raster map named 'elevation' in the spearfish dataset, but e.g. 'elevation.10m' as seen in one of the screenshots in the quickstart. This should be corrected throughout the quickstart. It seems that the basins in 'Watersheds and streams' were created with the minimum size of the exterior watershed basin threshold set to 100000 cells, not 10000 cells (missed a zero). > > > In addition, on the disc the QGIS-GRASS bridge is broken because > of this bug: > http://hub.qgis.org/issues/2947 > https://trac.osgeo.org/osgeo/ticket/868 The live dvd could use sextante for QGIS to access GRASS functionality. An added bonus would be that sextante has bindings to several GIS engines, one of them being GRASS, but others should also be already available on the live dvd.
