地理信息系统(GIS)是一种新兴的空间信息管理系统,具有空间分析、可视化、电子地图等功能,早已广泛应用于地理科学的各个领域,但在地理基础教育中却较少应用。等高线地形图的判读一直是初中地理教学的重难点,利用GIS软件绘制等高线地形图,实现等高线的三维可视化,可以帮助师生突出重点、突破难点。 Geographic information system (GIS) is a new spatial information management system. It has the functions of spatial analysis, visualization, and electronic map. It has long been widely used in various fields of geography science, but it is rarely used in geographical basic education. The interpretation of contour topographic maps has always been a major difficulty in geography teaching in junior middle schools. Using GIS software to draw contour topographic maps to achieve three-dimensional visualization of contour lines can help teachers and students highlight key points and break through difficulties.
