Indexing Range Sum Queries In Spatiotemporal

The Rtree is known to be one of the most popular index structures to efficiently process window queries in spatial databases. Intuitively the aggregate Rtree aRtree improves the Rtrees performance in range sum queries by storing in each intermediate entry preaggregated sums of the objects in the subtree. Fig. 1 shows an example of an aRtree.
