Gray Geographical Information System-the Theory and Technology of Correct Geological Spatial Data Dynamically

Abstract

Abstract: Concept of GGIS(Gray Geological Information System), together with integrated data model and data structure of 2D-GGIS and TIN, of 3D-GGIS and ARTPN(Analogical Right Triangular Prism Network) are therefore put forward in the paper. It lays a basis for realizing geological data dynamic management. Moreover, the key technology of automatically creating TIN and ARTPN is discussed.

Key words: geological data, dynamic, gray, gray geographical information system(GGIS), data model, TIN, ARTPN

摘要： 提出了灰色地理信息系统(Gray Geographical Information System, GGIS)的概念以及2D-GGIS与TIN，3D-GGIS与ARTPN(Analogical Right Triangular Prism Netuork)一体化的数据模型，为实现地质数据的动态管理奠定了基础。此外，对自动生成TIN、PEN的关键技术进行了论述。
