This is what is happening already provided you're providing the image with 0-1-...7 to GeoServer for display and use the raster symbolizer to turn the numbers into colors. For reference see the sf:dem layer we have in the GeoServers you can download, or see this online version: http://demo.opengeo.org/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=sf:sfdem&styles=&bbox=589980.0,4913700.0,609000.0,4928010.0&width=512&height=385&srs=EPSG:26713&format=application/openlayers Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
