On-Line Discovery of Dense Areas in Spatio-temporal Databases
[chapter]
2003
Lecture Notes in Computer Science
Moving object databases have received considerable attention recently. Previous work has concentrated mainly on modeling and indexing problems, as well as query selectivity estimation. Here we introduce a novel problem, that of addressing density-based queries in the spatio-temporal domain. For example: "Find all regions that will contain more than 500 objects, ten minutes from now". The user may also be interested in finding the time period (interval) that the query answer remains valid. We
