Hi stephen, May be this? g.region rast=`g.mlist pat=srtm* sep=,` r.series input=`g.mlist pat=srtm* sep=,` output=srtm_leste method=maximum
of you can play with r.mapcalc to identify where is zero, and calculate the mean using [-1,-1][-1,0],.... [1,1] (not use [0,0]) to average (sum/8). good luck, miltinho 2009/8/21 Markus Neteler <[email protected]> > On Sat, Aug 22, 2009 at 12:33 AM, stephen sefick<[email protected]> wrote: > > I have four maps that I would like to patch together.
