| Abstract: | As the developing of Smart City,traditional 2d GIS System have a strong desire to integrating with 3d GIS System,the new system not only can use the powerful Spatial Analysis and the flat panel display of 2d GIS system,but also can use the 3d GIS Virtual Reality Capability to get an advance simulation display of city which 2d GIS unreachable. This paper studies the implementation technique and the result of the system integrating 2d GIS and 3d GIS that based on OSG VR Engine and Flex RIA. |
