Markus, Thanks for your assistance and explanation. I ended up adding +1 and multiplying by 100 the source raster....
e.g. r.mapcalc "new_raster=(old_raster+1.0)*100" I also transformed the ndvi color table accordingly, and post it here if anyone should wish to use it... 0.00 5 24 82 70.0 5 24 82 82.0 255 255 255 100.0 255 255 255 102.5 206 197 180 107.5 191 163 124 112.5 179 174 96 115 163 181 80 117.5 144 170 60 123.3 166 195 29 126.6 135 183 3 133.3 121 175 1 136.6 101 163 0 143.3 78 151 0 146.6 43 132 4 155.0 0 114 0 165.0 0 90 1 175.0 0 73 0 185.0 0 56 0 195.0 0 31 0 200.0 0 0 0 Thanks, Bill On Fri, 2010-04-02 at 23:10 +0200, Markus Neteler wrote: > <grass-user@lists.osgeo.org> _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
