I finally solved it. For the benefit of the next victim, here's the solution. The problem was > r.out.tiff -t -v in=srtm30_$reg out=srtm30_$reg presumably in combination with the colour bucket discussion at http://mapserver.gis.umn.edu/docs/howto/raster_data . Substituting r.out.gdal input=srtm30_$reg format=GTiff type=Int16 \ output=srtm30_$reg.tif createopt="TFW=YES" for the r.out.tiff command creates 1-band tiffs, which mapserver then can colour uniformly with class statements like CLASS NAME "Elevation 1500-2000m" EXPRESSION ([pixel]>=1500 AND [pixel]<2000) COLOR 254 153 41 END On a totally different subject, wouldn't it be better to have the list's reply-to set to the list rather than to the sender, so that replies get archived by default and can benefit more people than just the person asking a question? Z -- The best defence against logic is ignorance. The next best is stupidity. Both can be used simultaneously.
