基于ArcGIS的钻孔和地质体的三维可视化研究与实现

The Study and Realization of 3-Dimensional Visualization of Drilling and Geologic Body Based on Arc GIS

钻孔数据能够记录大量的地质实体单元原始信息.针对钻孔和地质体的基本特征及真三维建模要求,采用E-GTP模型、多层DEM-GTP模型,并结合真实的钻孔资料以及各种勘查资料,实现了基于Arc GIS的地下钻孔、三维地质体可视化建模.重点解决了隐伏于地下透镜体的三维可视化,对于实现地质勘查工作的数字化和信息化具有重要的现实意义.

Drilling data can record a large number of the original information of geological entity unit. Considering of the basic features and demands for real three dimension （3D）spatial modeling of drilling and geologic body, we used E-GTP model and multi-layer DEM-GTP model that combined with the real drilling data and various kinds of exploration data to implement the 3D visual modeling of the underground drilling and 3D geologic body based on ArcGIS. The study focuses on addressing 3D visualization of the concealed underground lens, and it has important practical significance to realizing the digitalization and informatization of geological prospecting work.
