AbstractThe spatial join operation matches two sets of geometric descriptions by means of a geometric predicate. This work concentrates in algorithms based in space subdivision, presenting a new algorithm, based on PBSM, called PBSM-NRQB (No-Replication, Quadtree, Bucket). This algorithm uses statistical information, maintained in quadtrees, to adapt the space partitioning to object distribution and uses a file organization, based in buckets to store object descriptors in a more convenient way. The comparison with others algorithms in literature are made by performance analysis and experimental results obtained using synthetic and real data sets, showing that the algorithm is very competitive in all the situations, reducing the number of I/O operations and response time in almost every case.
