Benchmarking Spatial Join Operations with Spatial Output
The spatial join operation is benchmarked using variants of well-known spatial data structures such as the R-tree, R-tree, R+-tree, and the PMR quadtree. The focus is on a spatia...

Benchmarking Spatial Data Warehouses
Spatial data warehouses (SDW) enable analytical multidimensional queries together with spatial analysis. Mainly, three operations are related to SDW query processing performance: (...

Pipelined spatial join processing for quadtree-based indexes
Spatial join is an important yet costly operation in spatial databases. In order to speed up the execution of a spatial join, the input tables are often indexed based on their spa...

Incremental Distance Join Algorithms for Spatial Databases
Two new spatial join operations, distance join and distance semijoin, are introduced where the join output is ordered by the distance betweenthe spatialattribute values ofthe join...

Common Influence Join: A Natural Join Operation for Spatial Pointsets
We identify and formalize a novel join operator for two spatial pointsets P and Q. The common influence join (CIJ) returns the pairs of points (p, q), p P, q Q, such that there e...
