the region is set from the outer bound of a cell. For example, a 1x1 cube is centered at 0.5,0.5 within a region of 0,1 0,1: G63> g.region -p n=1 s=0 e=1 w=0 res=1 G63> r.mapcalc one=1 G63> r.out.xyz one 0.5|0.5|1 see the first few lines of rasterintro.html Hamish _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
