Abstract: Through the 3D modeling,rendering and roaming customization process by using the Google SketchUp6.0 software platform,the initial construction of a three-dimensional GIS system for the mining park experimental prototype is obtained at the base of 2D vetor data of a mine park.Combining with the Google SketchUp6.0 software, the prototype can realize the interaction with the ArcGIS software.The development work of 3D mine park scenario-driven can be done effectively by using ArcGIS software,so as to form a real 3D model of a mine part scene reproduction.The modeling effects in Google SketchUp6.0 software and the browse roaming functions of various controls in ArcGIS Engine sotware are unified,so a simple 3D view of mine park roaming system can be acquired. 　　

Key words: Google sketchup6.0 software, 3D model, ArcGIS engine, 3D roaming system
