摘要
三维地学模拟是三维地质信息GIS可视化的核心内容。基于基础GIS软件平台MAPGIS,利用功能强大的三维可视化开发平台MAPGIS-TDE,设计、开发具有自主版权的三维地质建模及可视化系统。MAPGIS-TDE包括MAPGIS内核模块、MAPGIS-TDE基础平台、MAPGIS-TDE构建平台和基于MAPGIS-TDE的应用系统等4个层次。基于MAPGIS-TDE的三维地质建模及可视化系统分为地质数据管理、二维地质分析、地质断面处理、地质结构建模和地质属性建模等5大功能模块。系统实现时,将空间数据库划分为基础地理图形库、区域地质数据库、工程地质数据库、水文地质数据库、地球物理数据库、地球化学数据库等6类。该系统不仅提供了强大的地质数据管理、三维地质建模以及模型的可视化功能,还为专业技术人员提供了一个可视化的分析、设计平台。
3D geoscience modeling is the key technique issue to the visualization of 3D geological data using GIS. Based On MAPGIS-TDE, the software system ＂3D geological modeling and visualization＂ is designed and established. MAPGIS-TDE, which is a powerful toolkit for 3D visualization, has a hierarchical structure composed of the kernel module of MAPGIS, the basal platform of MAPGIS-TDE, the construction platform of MAPGIS-TDE and the application system of MAPGIS-TDE. 3D geological modeling and visualization system has five functional modules as data management, 2D analysis, cross-sections processing, geometry modeling and property modeling. By integrating geographical database, areal geology database, engineering geology database, hydrological geology database, physical geology database, geochemistry database with 3D geological modeling, the system realize such functions as data management, 3D geological modeling and the visualization of 3D geological model. It is a visualization platform that assists the design and analysis for the geologists and the technologists.
