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...

Assuming a setting where the index updates need not be written to disk immediately, we propose an R-tree-based indexing technique that does not exhibit any of these drawbacks. This technique exploits the buffering of update operations in main memory as well as the grouping of operations to ...
