The source code for r.in.tiff and r.out.tiff are in the src.contrib/SCS/raster/r.tiff directory. I got them to compile and work OK, although I had to make an adjustment that I don't recall. Both r.in.tiff and r.out.tiff work fine for bringing in scanned imagery. Bill Baker bakerwl at corral.uwyo.edu Univ. of Wyoming
