摘要
随着计算机技术及信息技术的不断发展和数字化概念在测绘中的应用不断深入,数字高程模型(DEM)越来越成为地理空间基础设施和“数字地球”的重要组成部分。在GIS蓬勃发展的今天,DEM的数据源和建立方法将是测绘和GIS领域重点研究的课题之一。
     本文主要介绍了数字高程模型的数据获取方式及建立方法,并介绍了数字高程模型的特点、分类和表示方法及特征,对DEM的两种主要表示方式进行了比较;狄洛尼三角网是TIN中最优的三角网,文中还介绍了狄洛尼三角网的三种生成方法及TIN的线形内插方法,并简单探讨了DEM的精度估计。ArcGIS 8是一个统一的地理信息系统平台,本文通过实例,介绍了运用ArcGIS软件中Arc Catalog、Arc Toolbox、Arc Map、Arc Scene以及AutoCAD建立不规则三角网(TIN)模型的过程。最后提出了结论和展望。
As the technology of the computer and information have constantly developing and the application of the digitized concept in surveying is deepened constantly, the survey taking " 3S "、" 4D " as main means of production has already become the new developing information industry, is getting attention from various fields of society day by day , Digital Elevation Model (DEM) become an important component of geographical space infrastructure and " digital earth " . Today, GIS is vigorous, the data source of DEM and its method of setting up will be one of the key research subjects in surveying and GIS domain.
     This text mainly introduce the way to obtain datum and the method to setup Digital Elevation Model, recommend the characteristic, classification and the expressing methods and characteristics of classification for Digital Elevation Model, compare the two mainly methods to set up DEM; Triangular network of Delaunay is the optimum triangular network in the TIN, this text also recommends three methods to setting up Triangular network of Delaunay and linear interpolation of TIN also is introduced in the article, and the precision's estimation of DEM is briefly disscused. ArcGIS 8 is a unified geographical platform of GIS, this text select ArcGIS software to set up DEM model, and recommends the process to set up the irregular triangular net work (TIN ) model using Arc Catalog in ArcGIS software, Arc Toolbox , Arc Map , Arc Scene and AutoCAD. Finally have proposed the conclusion and looked forward the future.
