摘　　要：该文针对GIS专业DEM教学的现状和特点,根据实验教学内容的设计原则,制定了DEM专题实验教学内容,涵盖DEM的基本概念、算法和处理方法,包括DEM数据模型、特征提取、多尺度特性、数据内插、质量分析和表达绘制。充分借助商业和开源GIS平台等实验教学平台搭建实验环境,通过验证性实验操作和算法实现性实验,全方位地突出DEM专题的教学内容,探索出一种DEM专题实验教学的过程。将GIS专业课程的DEM教学内容层次分明地贯穿于实验过程中,对于巩固学生的专业知识,提高学习能力起到积极作用。According to the principle and characteristics of the digital elevation model(DEM)teaching in the geographic information system(GIS)major,the DEM thematic experiment teaching content is developed to cover the basic concepts,algorithms and processing methods. The teaching content includes the DEM data model,feature extraction,multi-scale features,data interpolation quality analysis,and data rendering. Commercial and open-sourced GIS platforms and other experimental teaching platforms have been made fully use to construct the experimental environment. Through the experiments of verification and algorithm implementation,the content of the DEM topic is highlighted in various aspects. A process of the DEM thematic experiment teaching has been established to help students to consolidate their professional knowledge.
