R-tree Structure Appended with Spatial Topology Restrictions in 3D GIS
After detailedly researching on the mechanism of R-trees and combining with the 3D entity object,a bran-new R-tree structure appended with topology restrictions in 3D space is presented,four rules are defined which enable to decrease the overlap of R-trees' area when constructing spatial indexes and enhance the query efficiency assuredly.
