Display Geotiff-Data: Problems

[Oliver Wesp]

Hi,

I guess you're using 256 color output so the rgb image is mapped to 256
colors. Switching to rgb output should solve the problem. Put something
like this in your mapfile

IMAGETYPE PNGRGB
OUTPUTFORMAT
 NAME PNGRGB
 DRIVER "GD/PNG"
 IMAGEMODE RGB
 TRANSPARENT OFF
END
