Is there any way to get GeoServer to render more than 255 colors for my geotiff? I can create a .sld with over 500 ‘colorMapEntries’, add it to GeoServer, and even add it as the default style for my layer. However, GeoServer throws an error when I subsequently do a ‘GetMap’ request on the WMS. Maybe there’s a way to embed a large colormap into my tiff that I’m not aware of?
Thanks for any help.

Hi Don,
have you tried the “extended” attribute of the element?
extended
The extended attribute specifies whether the color map gradient uses 256 (8-bit) or 65536 (16-bit) colors. The value false (the default) specifies that the color scale is calculated using 8-bit color, and true specifies using 16-bit color.

I think the 'extended' parameter worked. Thanks, Peter!
