Abstract
A method of updating information stored in an index associated with spatially-related objects. The method includes accessing a hierarchical multi-level index having leaf nodes containing information about an object and non-leaf nodes storing information about a number of nodes related to the non-leaf nodes, adding a representation of the object at a leaf node in the index, and traversing parents of the leaf node toward a root node, and incrementing counts of each node in the traversal path.
