WebBSP trees are useful for building an "exact cell decomposition". A cell is any region which is used as a node in a planning graph. An exact cell decomposition is one in which every cell is entirely occupied, or entirely empty. The alternative is an "approximate cell decomposition", in which cells may also be partially occupied.
