Indexing spatio-temporal data warehouses [PDF]

Proceedings 18th International Conference on Data Engineering, 2003
Spatio-temporal databases store information about the positions of individual objects over time. In many applications, however, such as traffic supervision or mobile communication systems, only summarized data, like the average number of cars in an area for a specific period, or the number of phones serviced by a cell each day, is required.
