摘要
本文在作者提出的地质体几何造型概念及理论基础上,利用关系数据模型扩展、图论构模、集合构模等方法,给出了地质体几何造型系统的基本实现途径和方法,主要包括地质体几何造型的数据结构、模型构造及地质体的几何运算与整体性质分析,以实现地质体的几何、拓扑和属性3个方面信息的计算机存储、建模、表达和分析,以此可构造出诸如地测图件自动生成等各种地质体几何造型应用系统。
Based on the concept and theory of geologic bodies' geometric modeling proposed by the authors, by means of the extension of relation data model, graph theory, set theory and other modeling techniques, this paper presents the elementary ways and techniques for building computer system of geometric modeling of geologic bodies, mainly including the data structure of geologic bodies' geometric modeling, construction of geologic bodies' models, geometric operation and entirety properties' analyses of geologic bodies, which have achieved the computer storage, modeling, representation and analysis of the geometric, topological and attribute information of geologic bodies. According to these, we can build various application systems of geologic bodies' geometric modeling such as the automated generation system of geologysurvey maps.
