- For indexing spatial data, some methods (R-trees) enclose each spatial object
- in a Minimum Bounded Rectangle (MBR) in the n dimensional space and all index
- operations eventually turn into spatial, geometric operations involving these
- rectangles(cubes etc) such as finding how much they overlap, least area
- enlargement to include one another, intersection etc. I am looking for
- source code which performs these kind of geometrical operations. Also any
- advice on the efficient representation of spatial objects by mimimum
- bounding rectangles would be appreciated. Do you know any _book_, paper
- references on these kind of spatial algorithms and data structures?

- Since I don't often read this news group. would you please send your replies
- to my email address.

- thanks in advance
