Now that's good news, welcome on board (really hope you can choose geotools for good) :-) > We are a company working basically on environmental informatics and > geodata processing, and we have two applications for which Geotools is a > strong candidate to be used within.

Geoserver does use a plain sequential one. Some more research in this topic is needed, but I'm personally very interested in the topic. I hope we can have a fruitful collaboration Cheers Andrea Aime ------------------------------------------------------------------------- Take Surveys. Earn Cash.
