铁路线路三角网数模及地面高程内插系统研究

Study of Triangulated Irregular Network and Interpolating Terrain Elevation In Railway Location

阐述了铁路线路带状数字地形模型的概念 ,提出了不规则三角网数模及地面高程内插系统的总体结构和数据结构 ,介绍了带状数模的模型建立过程及数据索引技术。

In this paper,the concept of strip Digital Terrain Mode(DTM)in railway location is explained.The general structure and hierarchical structure and data structure of Triangulated Irregular Network and interpolating terrain elevation are presented.The model making progress and data index technology of strip DTM are also intyoduced
