r.mapcalc doesn't have a definition for pi; you'll need to enter a literal value. Note that all of r.mapcalc's trigonometric functions accept or return angles measured in degrees, so you don't need to explicitly multiply or divide by pi/180. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
