Abstract
This paper is based on the theoretical research of visual reality geographical information system, includingthe acquisition of three-dimensional space model, three-dimensional data model, Digital Terrain Model, DigitalElevationModel and the exp ression of levels of detail of 3D space date and three-dimensional data visual exp ressionetc. Based the ArcEngine as tool, this paper created virtual reality topographical scene of Zijin mountain region,realized the interactive operation, just like Zooming in, Zooming out, Rotating, Roaming and Simulating, andSAconstructed a case of VRGIS on Zijin mountain region.
