r.univar can take multiple multiple maps as input and from that you could get max. r.slope and others would work best on a VRT or r.patch from the individual rasters. > Are there alternatives to a virtual raster for situations like this? r.patch? Or for loop over all the individual rasters w/ r.info to find the max? That won't work for r.slope because of edge effects. A VRT is probably easiest / best. -k. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
