Abstract: We examine the problem of eciently computing sum/count/avg aggregates over objects with nonzero extent. Recent work on computing multi-dimensional aggregates has concentrated on objects with zero extent (points) on a multi-dimensional grid, or one-dimensional intervals. However, in many spatial and/or spatiotemporal applications objects have extent in various dimensions, while they can be located anywhere in the application space. The aggregation predicate is typically described by a... (Update)
