基于三维GIS的地理教学辅助系统设计与开发

Nowdays,informatization of basic geographic education is gradually heading towards in-depth,3D GIS-based geography teaching auxiliary system is given rise to concern due to its outstanding visualization,good interactivity.This paper discusses construction goal、design idea、technical framework and the use of main functions of 3D WebGis geography teaching auxiliary system developed based on the Google Earth API.Practices show that this system not only help student better understand geography Knowledge through 3D GIS,but also improve their enthusiasm in geography.As the application of 3D GIS in geography teaching is in exploration, in the end,this paper proposes 3D modeling、simulation of geographical event process and overlaying local geographic data of the system is also to be explored.
