A system architecture for heterogeneous moving objects trajectory models using different sensors

This paper proposes a general trajectory's meta-model and its architecture. In order to provide a unified meta-model and a powerful framework for trajectory's services and queries, the proposed trajectory's data-model has benefited from advantages of both conceptual and ontological space-time. However, it extends the basic data-model of trajectory with new patterns as Space Time Path to describe activities of the moving object, and Composite Region of Interest. Additionally, the proposed system is distinguished by providing framework for dealing moving objects trajectory, in an interoperable way, using heterogonous sensors that traditional data model alone are incapable for this purpose. The proposed system architecture for moving object trajectory's data-model is focused on service composability and data interoperability combining OGC standards, Service-Oriented Architecture and streaming technology, to allow applications constructed using the framework have better performance.
