Validity Information Retrieval for Spatio-Temporal Queries: Theoretical Performance Bounds
The results of traditional spatial queries (i.e., range search, nearest neighbor, etc.) are usually meaningless in spatio-temporal applications, because they will be invalidated by the movements of query and/o...
