The SBS: an efficient index structure for spatial database applications
Proceedings 11th International Workshop on Database and Expert Systems Applications
In reality spatial objects (e.g., Dams) not only have spatial locations but also have quality attributes (e.g., height, reservoir capacity).Given a spatial location S, Quality vector ψ and a set of spatial objects D, a spatial query which retrieves and ranks the objects that intersect the region S and satisfies the quality vector. Based on the inverted index and the linear quad tree, we propose a novel index structure, called inverted linear quad tree (IL-Quad tree), which is carefully designeddoi:10.1109/dexa.2000.875126 dblp:conf/dexaw/Al-BadarnehF00 fatcat:u3zkktg66zftthkz2dz26fjdge
