Integration of SATURN System and VGIS

Abstract

This paper reports on the integration of the SpAtio-Temporal Uncertainty ReasoNing (SATURN) system being developed in our group with the Virtual GIS (VGIS) system in order to improve its performance and scalability to complex dynamic environments as well as to enhance its functionality as a collaborative planning tool. To achieve this we added three new components to VGIS: a spatiotemporal object manager, a performance monitor, and a task database. The spatio-temporal object manager uses SATURN techniques for indexing dynamic multidimensional (spatio-temporal) objects to support effective and efficient object traversal during visualization. The performance monitor adjusts the resource allocation between VGIS components and adaptively adjusts image quality to guarantee bounded visualization performance. The task database extends VGIS as a tool for collaborative planning. Performance results illustrate that the SATURN techniques for object management and the performance monitor significantly improve VGIS performance allowing it to scale to complex scenarios with a large number of dynamic objects.
