Video surveillance GIS: A novel application

The integration of GIS and video surveillance systems is very useful for security and city management, which can provide real-time spatial-temporal information and display them on electric map. The key technology mainly includes the mapping between videos and map, the tracking for dynamic objects. Firstly, we propose an integrated framework of GIS and video surveillance system. Secondly, we present a cross-mapping model between videos and 2D GIS. Then, we describe a semi-automatic cross-mapping method based on 2D GIS and some constraints, which needs less interactions and can easily to be used, especially in city management. Finally, we develop a prototype system and discuss the implementation details including cameras´ views display in 2D GIS using the cross-mapping model. Test results show that Video surveillance GIS (VSGIS) is very useful for the city safety management.
