Research of 3D Automatic Modeling Method of Mine Laneway Based on ArcGIS Engine and Its Implementatio

The paper compared and analyzed 3D modeling technologies of mine laneway,put forward a 3D modeling method of mine laneway based on MultiPatch 3D data structure in ArcGIS.Considering characteristics of mine laneway,the method realized 3D automatic modeling of mine laneway based on secondary development on ArcGIS Engine platform under the C# developing environment.The method provides a new solution for establishment of 3D mine laneway information system.
