摘要
三维地质建模是研究如何利用GIS软件将三维空间地质实体真实地再现,实现地质体的三维可视化和相关空间分析,为地质研究和矿产资源勘查提供技术支撑。本文在综合前人研究成果的基础上,对目前常用的基于MapGIS的三维地质建模方法进行了总结,并提出了一种利用四叉树算法优化检索效率的三维建模技术,对于解决城市地质、工程地质、环境地质、三维地质填图中的三维建模问题具有重要意义。
Three-dimensional geological modeling is to study how to obtain the realistically reproduction of the three-dimen- sional space and geological entity by GIS. It is able to realize three-dimensional visualization and correlation space analysis, pro- viding technical support for geological research and mineral exploration. On the basis of previous research findings, several cur- rent three-dimensional geological modeling methods based on MapGIS are summarized. In addition, an improved threedimen sional modeling technology with optimization of retrieval efficiency taking advantage of quatree algorithm is proposed. It has significant meaning for solving problems related to urban geology, engineering geology, environmental geology and three-di- mensional geological mapping.
