At the moment there is no out of the box way to do so. There are things under construction that can do it though: - the new security subsystem (http://geoserver.org/display/GEOS/GSIP+57+-+Improving+GeoServer+authorization+framework) allows to write a custom security implementation that cuts rasters on the fly, we have it working but not released to the public right now (it uses a lot of API from the customer that sponsored its development, it's not generic) - on trunk (what will become 2.2.0 in 6 month to one year time) the "rendering transformations" feature allow one to chain a wps process into the sld, in particular one could chain the gs:crop process that does exactly what you want, cookie cut a coverage on a user provided polygon. We have a blog post showing different kind of processes, but the machinery remains the same http://geo-solutions.blogspot.com/2011/01/developers-corner-have-your-sld.html Cheers Andrea -- ------------------------------------------------------- Ing.
