基于MapGIS的数模建立方法及其在路线CAD中的应用

A Study of Creating Digital Terrain Model and its Application in Highway Route CAD Based on MapGIS

针对公路勘测设计一体化的特点与要求,论述应用GIS技术采集公路地面数据和建立数字地面模型的方法;研究MapGIS系统在公路选线和CAD中的应用。在分析地理信息系统与公路勘测设计关系的基础上,根据我国公路路线设计CAD发展的实际情况,提出基于MapGIS平台进行公路路线设计应用软件开发的建议。

Aiming at the characteristic and request of highway survey and design integration,this paper discusses the methods of gathering highway ground data and set up digital ground the methods of models by GIS technology; Study applications of MapGIS in the highway route selection and CAD.According to development situations of highway route design CAD in our country, an idea that the development of our country's highway design CAD should be based on an advanced MapGIS platform are presented after analyzing the relationship between GIS and highway design..
