随着三维GIS技术的不断发展,对于在工程项目中建立三维可视化分析管理系统的需求越来越高。准确分析识别地下区域的岩石块体信息,是地下工程施工与监测中需要解决的关键问题。本文基于空间拓扑关系的知识,在地质模型抽离岩石属性图层,设计了空间查询体,进而利用Skyline平台的接口,探索出一种能够实现模型岩性点触检测功能的方案。
With the continuous development of three-dimensional GIS technology, there is an increasing demand for establishing a three-dimensional visual analysis management system in a project. Accurately analyzing and identifying rock block information in underground areas is a key issue to be solved in the construction and monitoring of underground engineering. Based on the knowledge of spatial topological relations, this paper designs a spatial query body by extracting the rock property layer from the geological model, and then uses the Skyline platform interface to explore a scheme that can realize the lithology touch detection function of the model.
