Processing and optimization of multiway spatial joins using R-trees

Abstract
One of the most important types of query processing in spatialdatabases and geographic information systems is the spatial join,an operation that selects, from two relations, all object pairssatisfying some spatial predicate. A multiway join combines dataoriginated from more than two relations. Although severaltechniques have been proposed for pairwise spatial joins, onlylimited work has focused on multiway spatial join processing.This paper solves multiway spatial joins by applying...
