An Investigation on Patterns that Affect the Performance of Spatial Joins Sandro D. Gatti and Geovane C. Magalhaes   View Paper (PDF)   Return to Spatial Databases Abstract This paper analyses spatial index methods for spatial joins, considering factors such as bufferpool size, buffer replacement policies, page size and intermediate join indexes ordering criteria. This analysis was based on real data, taken from a GIS application for public utilities. Results of this work assess the way those factors affect spatial join performance and can be used for tuning their methods. DiSC'01 Copyright ©2002 ACM Inc.
