Dear GRASS users, I'm a new GRASS user, and need to calculate the percentile rank of a cell within a moving window. Specifically, from a raster of wildlife habitat quality (ranked from 1 to 100) at 100m resolution, I would like to find the percentile rank of each focal cell relative to all of its neighboring cells within 20km of the focal cell - with an analysis extent of the western United States.
It looks like r.neighbors calculates other moving window statistics (but not percentile rank), and r.univar calculates percentile rank. Is there a module that does both, or a way to make r.univar calculate percentile rank within a moving window? Would there be a relatively simple way to script this? Many thanks, Tristan _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
