I need to convert a vector contour map to a raster so I can apply the hydrologic models modules.
Reading the v.to.rast manual page I learned that I needed to add categories to the input contour map. Running v.category added no categories: "0 features added." v.info does not tell me anything about the elevation values of the contour lines. Looking at the v.* modules, and trying v.univar, didn't help. I could try v.to.3d, but I need information about the vector map's contents. Which v.db* should I use to find the elevation colum associated with each contour line? TIA, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
