Thank you guys, Andrea - I tried to include your example in GeoTools-2.5.4 but i got some errors in CachingFeatureSource class, e.g. FeatureType.getTypeName() is called but it didn't exists and similar.
Jody - Does in GeoTools currently exists some engine for rendering 2D maps in "tiles"? I know that there is 3D map renderer.

To achieve substantial improvements one needs in memory caching. It's not a topic I have a personal interest into, but I did provide some time ago a caching feature source + spatial index that can be used to significantly speed up drawing for small amounts of data. There is also a caching module in unsupported made last year by a summer of code student, but I really never tried it out so I cannot comment on its speed/functionality. Anyways, it's still in the gt2-users archives, here: http://n2.nabble.com/Render-with-gt2.3.1-td1939887.html#a10160606 Cheers Andrea ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
