摘要
数字高程模型的是"数字地球"概念中的核心技术.数字高程模型具有运用多样性的特点,在实际生活有广泛的应用性。文章中提出用地理信息系统3D功能和数字高程模型形成的线性模式与计量地理学的相关知识形成数字高程模型的方法,并以新疆师范大学为例介绍数字高程模型的应用性并在DEM上建立新疆师范大学可视三维模型.
Digital elevation model（DEM）is very important technology in digital earth, digital elevation model has strong, applicable and maneuver abilities. Establish DEM has a lot of method in realm of GIS （Geographical information system）, in this paper I has put forward the line mode method, geographical information system＇s 3D（Three-dimensional） function ,and related knowledge of quantitative geography, established the DEM. this work have meaningful use in our real life work. At last, take normal university of Xinjiang, as an example, to introduce DEM application, and established Xinjiang normal university 3D model on this DEM.
