Hi Ian and Andrea,
I wrote down my plan for using a quadtree to cache features :
http://docs.codehaus.org/display/GEOTOOLS/SoC+2007+Caching+data#SoC2007Cachingdata-ideasquadtree
Could you have a look at this ?
I implemented a stub quad tree for this purpose, based on
org.geotools.index.quadtree.QuadTree, but this new implementation suits
better my needs, as I can use visitors to query the tree and query
strategies to traverse the tree by level.
This tree is in package org.geotools.caching.quadtree.
Thank you,
Christophe
