Location prediction and queries for tracking moving objects
Ouri Wolfson, B. Xu, Sam R. Chamberlain · 2002
Our Mobitrack prototype is intended to serve as a platform, or a toolkit for developing moving-objects-database type of applications. The system is the third in a three-layer architecture. The first layer is an object relational DBMS. The database stores the information about each moving object, including its plan of motion. The second layer is a GIS that adds capabilities and user interface primitives for storing, querying, and manipulating geographic information. The third layer, Mobitrack, adds temporal capabilities, capabilities of managing the uncertainty that is inherent in future motion plans, capabilities for location prediction, and a simulation testbed. Currently, Mobitrack runs on both Unix and MS Windows. On both platforms Mobitrack uses the Arc-View GIS. It uses the Informix DBMS on Unix, and DBAccess on MS Windows.
