三维建模是ArcGIS的重要应用,结合实例,介绍了在GIS环境下构建三维地质模型常用的方法,提出并详细阐述了基于面模型构建三维水文地质模型的层面-体视化建模方法。该方法以钻孔资料为基础,在GIS环境下建立三维水文地质模型并实现了在网上面向对象的三维可视化,对类似问题的研究具有一定的借鉴意义。 更多还原

【Abstract】 Three-dimensional(3D) model is an important application of ArcGIS,common methods that construct 3D geological model were introduced with real examples in this article.And Volume Visualization Model which based on construction of 3D surface model of the level of hydro-geological model was proposed and elaborated.These methods which based on borehole data,constructed 3D hydro-geological model and achieved visualization of object-oriented on the Internet.The study had some reference meanings to the... 更多还原
