Spatial indexing has been one of the active focus areas in recent database research. Several variants of
Quadtree and R-tree indexes have been proposed in
database literature. In this paper, we first describe
briefly our implementation of Quadtree and R-tree
index structures and related optimizations in Oracle Spatial. We then examine the relative merits of
the two structures as implemented in Oracle Spatial
and compare their performance for different types of
queries and other operations. Finally, we summarize
our experiences with these different structures in indexing large GIS datasets in Oracle Spatial.
