[mapserver-users] adding a palette to a greytiff

[Alexander Petkov]

For some reason I can;t get to the file you posted, so I have a few question.

1. Is your file indeed georeferenced?
2. The style definitions look good, the only thing I see missing are
the class names. Not sure if that matters if you don't display a
legend.
3. Have you got the map file working without the class definitions?
I.E get a grayscale map?
4. Have you attempted to discover what is wrong by looking at the
mapserver log? You will need to enable logging in your map file.
