[Geoserver-users] Funny colors from WMS

Hi,

I am getting some funny bands of color in my coverage data that is being served up by GeoServer 1.5. Here is an example image: http://img134.imageshack.us/my.php?image=croppercapture1ng9.png

I had a bunch of tiffs and tfws and generated a load of Geotiffs and an index file before loading it into GeoServer. The GeoTiffs in question look fine in other GIS and image applications.

Any help would be appreciated.

Thanks
Jerry

If I understand correctly, you're loading an image mosaic, right?
If you load the single geotiffs instead, do they look fine?
Also, try to go the Geoserver configuration, server section, and
disable png and jpeg native acceleration, apply, save, and generate
again the images.
