range aggregate processing spatial databases

We rst review the range aggregate processing methods in spatial databases the range aggregate ra query was proposed for the scenario where users are interested in summarized information about objects in a given range rather than individual objects thus, a ra query returns an aggregation value over objects qualied for a given range in
