Patent abstract
The number of index entries in a grid index for indexing geometric shapes is reduced by establishing a pool storage area for geometric shapes, selecting a threshold number of grid cells which a geometric shape may overlap, storing the shape in the grid index if a geometric shape overlaps a number of grid cells not exceeding the threshold number, and storing the shape in the pool storage area if the geometric shape overlaps a number of grid cells which exceeds the threshold number.
