I would like to split data into spatial sectors and then start my analysis. E.g.: a) Create a 1km buffer around a coordinate b) Split this circle into sections (subareas) with a certain degree value. If I choose 1 degree the circle would be devided into 360 subareas c) Do my analysis in each sector I am thinking about a solution for b) regards, Otto _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
