Hi, I have added a new script to the wiki addons page: v.colors.
http://grass.gdf-hannover.de/wiki/GRASS_AddOns http://trac.osgeo.org/grass/browser/grass-addons/vector It is just like r.colors but for vector maps. You give it a vector map and data column, together with color rules like you would for a raster. It creates a new column in the database with R:G:B values suitable for use with 'd.vect -a'. Hopefully it helps supplement the ongoing thematic mapping efforts. It is mildly tested so far and pretty simple; seems to be ~75% error checking code. How it works: it creates a dummy raster map with the same data range as the vector's column then runs r.colors on that. Then it uses r.what.colors for each value found by v.db.select and uploads it to the DB. Better would be a C module which rendered directly instead of saving the colors in the DB. See also r.cpt2grass in the wiki addons for converting GMT color tables to GRASS's color table format. (for use with '{r|v}.colors rules=') enjoy, Hamish _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
