Don't worry man, I am just trying to light up some dscussion on this issue since it could be a good way to push forward the development. As of your involvement, you could do this, you could provide a brief description of what you are willing to achieve which could become one of the test-cases to drive the development, as well as some sample-data (which you already provided and I should already have somehwere on my laptop :-) ). I would like to see that other people think about this idea of development proposals (cholmes? aaime?). >If I > were more fluent (and felt more confident) in java I'd sponsor by > coding, but my java skills are very basic, and geoserver is imho a > pretty complicated project.

Give a detailed test-case and I can try to force we have in the background to work you. Not sure however about timing, but once we have a test-case we can see what we can do. > Anyways, I hope you do find some good sponsors, I think geoserver is > definely worth it and you guys do an awesome job! > I know, I know... :-) Thx, Simone. > Cheers, > Vincent. > > Simone Giannecchini wrote: > > Ciao Vincent, > > sorry to answer with such a delay, but we are quite busy these days. > > This email is of interest for anybody who's interested in styling > > coverage using a WMS+SLD with RasterSymbolizer > > Please, read below. > > > > On 1/9/07, Vincent Schut <[EMAIL PROTECTED]> wrote: > >> Hi all, > >> > >> I am encountering problems when trying to apply an sld with > >> rastersymbolizer to my coverages.
