Sounds a little like an R*-Tree. I recently reposted an old post from
Wout's list with definitions and descriptions of quadtrees etc. For me
the beauty of an R*-Tree is that it allows very easy localised processing.
To find all locally relevant data nodes, just ascend the tree from the
current location until you find a rectangle which bounds the requested
area. Another nice point is that multiple "thematic" schema can be easily
bound within the same R*-Tree.
