We propose the mqr-tree, a two-dimensional spatial access method that improves upon the 2DR-tree. The 2DRtree uses two-dimensional nodes so that the relationships between all obje...

We take another look at the 2DR-tree. In particular, we revisit its node structure, validity rules and the insertion strategy. The 2DR-tree uses 2D nodes so that the relationships...

We provide an evaluation of query execution plans (QEP) in the case of queries with one or two spatial joins. The QEPs assume R -tree indexed relations and use a common set of spat...
