have a look into the manual of r.horizon: https://grass.osgeo.org/grass74/manuals/r.horizon.html there is an example with the NC sample data set. test this example on your computer and see if it works. kind regards Helmut _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
