Abstract
A distance-associated join index structure is developed to speed up spatial queries, especially for spatial range queries. Three distance-associated join indexing mechanisms: basic, ring-structured, and hierarchical, are presented and studied. The analysis and performance study shows that distance-associated spatial join indices substantially improve the performance of spatial queries, and different structures are best suited for different applications.>
