A Web-based Tool for Spatiotemporal Filtering and Continuous Animation

We describe MoveMap, a front-end tool for spatiotemporal databases with moving objects. Built over the Google Maps technology, is independent of any underlying data model or query language. It accommodates continuous temporal navigation and aims to both precision and abstraction by employing the Google Maps DirectionsService utility. For filtering and controlling the display, it includes a set of spatiotemporal operators that can be dynamically triggered, as the navigation proceeds in time. Spatiotemporal querying is thus performed in two different layers; first at the server level which can be accomplished by any underlying framework and second on the client through this mechanism of associating query conditions to browser
