Video geographic information system using mobile mapping in mobilephone camera

In this Paper is to develop core technologies such as automatic shape extraction from images (video), spatialtemporal data processing, efficient modeling, and then make it inexpensive and fast to build and process the huge 3D geographic data. The upgrade and maintenance of the technologies are also easy due to the component-based system architecture. Therefore, we designed and implemented the Video mobile GIS using a real-time database system, which consisted of a real-time GIS engine, a middleware, and a mobile client.
