矿山地质勘察三维可视化管理系统与建模技术研究

以城市三维地质勘察管理信息系统为例，分析了地形三维数据模型的可视化表达与建模方法；基于组件GIS技术，通过将二维和三维空间信息统一在一个平台和数据模型下，建立了矿山三维地质勘察可视化管理系统。该管理系统可实现对数据的可视化管理及实时更新。可打印输出和三维显示地质图，并具有多种查询功能。对矿山地质体的空间数据管理和可视化表达，从理论、模型及技术实现上作了探讨。

Study on the Three-dimensional Visualization Management System of Mine Geological Prospecting And Its Modeling Technology

In this paper, taking the three-dimensional management system of city geological prospecting as an example, the visualization representation and modeling technique of 3D topographical data model are analyzed. Based on component GIS technology, by means of integrating the two-dimensional and three-dimensional spatial information into the uniform system frame and data model, a three-dimensional visualization management system of mine geological prospecting is established. This management system can realizes the visualization management and real-time updating of the data, the printing out and three-dimensional displaying of geological map, and offers many seeking ways. The management and visualization representation of spatial data of geological body is discussed from theory, model and technical realization.
