Abstract
In this paper, put forward a real-time navigation method adopted in the process of 3D virtual geographical scene roaming, which get the real combination between the virtual reality technology and mature GIS applications. And it has realized the entity location, property information, the management of the buffer zone and other functions through the geographical coordinates of the earth's counterpart in the 3D virtual geographical scene. However, the functions are likely to bring out only if it is in the 2-D environment previously. It has provided an effective assistance for the daily management. And the solution has been proved that not only is applicable to the basin simulation system development, but also has referenced value in involving the development of the GIS simulation.
