You can use "r.mapcalc" to achieve (almost) everything. Yet, for time-series, you can use the module "r.series". Have also a look at <http://grass.osgeo.org/wiki/Time_series> Regards, Nikos _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
