Automatic Construction Method of 3D Geological Model Based on ArcGIS
In order to improve the accuracy of 3D geological models,ArcGIS technology is introduced to design an automated construction method for 3D geological models.Based on ArcGIS and utilizing the ArcGIS Engine system,combined with the C#development environment,extract three-dimensional geological spatial points;Using the object model in ArcGIS to construct an indirect GIS data model;In order to be closer to the real 3D model,IGeometryMaterial in ArcGIS class library is used to design attribute data aggregation and geological structure texture mapping;Design geological data interpolation processing considering the spatial distribution changes of attribute data;Introduce a variation function,calculate the deviation value of the processed data,input the data into the ArcGIS platform,and automatically generate a three-dimensional stratigraphic model.The comparative experimental results demonstrate that this method can improve the accuracy of the 3D geological model and maintain a high level of matching between the random points in the 3D geological model profile and the geological reality.
