me too :-) in other words - I've also been trying to display single band coverages with float or double data. I've been trying to do it programmatically by creating a simple ColorMap and using this in the creation of a RasterSymbolizer. I then use GridCoverageRenderer.paint() with this symbolizer and get yet another grayscale image <sigh>
There are some sexy images of dems, temperature coverages etc on the geotools site. What's the secret ?
