基于MapGIS的图切地质剖面系统面向对象设计与实现

地质剖面图可以清晰反映图区内地层、岩体、构造的空间分布特征,对于认识各种地质体和矿床赋存的地质条件和时空分布规律具有重要的意义.在GIS环境下对数字地质图开展图切剖面软件的研究和开发是一项基础且重要的工作,图切地质剖面图不仅可为地质工作者认识地质特征提供基础图件,还可成为三维地质填图基础数据来源.介绍了基于MapGIS的地质图切剖面软件的系统设计方案,深入探讨了图切地质剖面软件研发中的面向对象设计方案,成功实现了面向对象的图切剖面的自动生成及交互修编功能.所研发的制图技术高效实用,能够满足各种比例尺的MapGIS地质图图切剖面的编制要求.

Object orientation design and implementation for cutting section of geological map system

The geological section map could reflect the spatial characteristics of various subsurface geobodies, such as strata, intrusions and structures. It was of important significance to understand the temporal and spatial distribution rules and occurrences of geobodies and ore bodies. Research and development of software for the geological section map of digital geological maps in GIS environment were a fundamental and important work, because the geological sections could reveal the geological features and provide basic data sources for 3D geological mapping. The authors introduced the system design for the cutting section of geological map based on MapGIS, explored the object orientation design method, implemented the functions for an automatic construction of geological sections and interactive updating. These mapping techniques developed were efficient and practical, which could fulfill the cutting section of geological map on various scales.
