oops, originally sent this just to Jody. This is using the GeoServer 'release' data; the style for this layer is the default GeoServer 'raster' style. (http://svn.codehaus.org/geoserver/branches/1.7.x/configuration/release/styles/raster.sld)
That said, this problem affects WCS GetCoverage requests, so SLD's should not be coming into the equation, as I understand it. -David Jody Garnett wrote: > Hi David; Emily and myself are working on raster symbolizer support in > uDig; and as such we are testing > some of the functionality you describe.
