It should be possible on trunk using the rendering transformations: http://docs.codehaus.org/display/GEOTOOLS/Rendering+transformations http://geo-solutions.blogspot.com/2011/01/developers-corner-have-your-sld.html With the WPS module loaded you should have the CropCoverage process handy, which can crop a coverage over any shape, chain it in the SLD, maybe use SLD variable substitution to get the geometry from the request URL itself and you should get a dynamic crop engine. The above is still a bit experimental, and not much documented, but if you have time to dig into the code you should be able to figure it out Cheers Andrea -- ------------------------------------------------------- Ing.
