A Spatial Index Based on Clipping Bounding Box of Space Partitioning Tree [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2022
In spatial databases, spatio-temporal indexes based on R tree use minimum bounding box(MBB)to approximate spatio-temporal data to improve query efficiency, and the efficiency of indexing can be further improved by by clipping the bounding box.To ...
