MPEG-7 metadata for video-based GIS applications

In this paper, we present a MPEG-7 metadata scheme designed for a video-based Geographic Information System (VideoGIS). Recently, VideoGIS have been developed for integrated management of spatial data such as map, 3D graphic, still image, and video to provide better and more realistic information of spatial objects. Main functions of VideoGIS are to calculate 3D geographic position of a spatial object and to search image and video that correspond to the object. In this paper, a MPEG-7 metadata scheme is proposed for emerging Location-Based Services (LBS), e.g., tourist information and restaurant reservation services, which becomes more and more popular in emerging mobile environments.
