GIS专业基于面向对象程序设计的DEM生成教学实验设计

数字高程模型是地理信息科学专业的必修课,DEM生成方法是该课程的核心知识点之一。通常以GIS软件为实验操作平台构建DEM,GIS软件提供良好的操作界面且简化教学过程,但软件同时会弱化学生对DEM生成过程的理解,而面向对象程序设计课程往往开设在数字高程模型课程之前。文中融合面向对象程序设计和数字高程模型课程知识点,采用面向对象程序设计思想对DEM课程中的DEM生成实验进行设计并实现,为GIS专业的DEM生成实验提供新的教学思路,提升DEM课程教学实践的品质和效果。

Teaching experimental design of DEM generation based on object-oriented programing design for GIS specialty

Digital Elevation Model (DEM ) is a required course for the Geographic Information Science (GIS) major .One of the core knowledge points of this course is the DEM generation method .GIS software as an experimental operating platform ,is used for construction of DEM ,w hich provides a friendly operating interface and simplifies the teaching process .But at the same time ,it weakens the students’ understanding of the DEM generation process .And object‐oriented programming courses are often set up before DEM courses .This paper integrates the object‐oriented programming and the digital elevation model courses knowledge points ,uses the thought of object‐oriented programming to design and implements the DEM generation experiment in DEM curriculum .A new teaching idea is provided for the DEM generation experiment of GIS major ,w hich ultimately can improve the quality and effectiveness of teaching practice .
