Direction Relations and Two-Dimensional Range Queries: Optimization Techniques

Abstract

Despite the attention that direction relations, such as east, southeast etc., have attracted in several domains related to Spatial Databases and Geographic Information Systems (GIS), little work has been done on their formalization and efficient processing. In this paper we define direction relations between two-dimensional objects in different levels of… (More)
