Modelling spatial video as part of a GIS video analysis framework

It is now common for video; real-time and collected, mobile and static, to be georeferenced and stored in large archives for users of expert systems to access and interact with. In the ground-based terrestrial context georeferenced video is also becoming more commonly collected from Mobile Mapping Systems (MMS) in recent years. However, significant problems exist for access to large volumes of archived georeferenced MMS video data in a GIS context. These include the semantics behind the modelling of its spatial content and the development of a computationally efficient query model that can isolate video sequences of geographical interest. These specific problems highlight a core difficulty when a geographical based video access query is required. Firstly, how can an optimised model of the video's spatial content be defined and, secondly, how can this spatial model be used to generate a meaningful spatial result. This paper outlines a georeferenced-video framework where a GIS-view...
