In a steady shift from traditional 2D--GIS toward 3D-GIS, a great amount of accurate 3D city models have become necessary to be produced in a short period of time and provided widely on the market. The authors have developed a system for automatic generation of 3D city models, using laser profiler data, 2D digital map, and aerial image, which are processed by the software newly developed. MapCube, the 3D city models generated by the system, has already covered all major cities of Japan at the end of 2002. Applications for virtual reality (VR) that deal with accurate and photo-realistic 3D city models are becoming indispensable in many fields. However, there had been no VR viewer that can appropriately deal with a great amount of 3D city data in real time. In order to solve the problem the authors have developed a new VR viewer called Urban Viewer that can make best use of 3D city models, especially MapCube. VR applications used on display devices should provide easy interactive operation. The authors have developed a new type of VR display device with optical sensors called NEXTRAX, which users can operate as easily as touch-panel display, with more accuracy of operation and much more durability. NEXTRAX also provides simultaneous display of co-related information including 3D city model, 2D digital map and varieties of multimedia information.
