摘要
地理信息系统的空间数据结构研究已日趋成熟,基于GIS(地理信息系统)技术的相关分析也相应地成为人们倍受关注的热点。文中以公路自然区划研究为基础,结合GIS空间分析模型分析我国DEM(数字高程模型)数据,生动形象地展示中国自然的海拔地貌,同时为地貌、水文、气候、植被等参数打好基础。结合ArcObjects和VB.net实现了专题地理信息系统。
The study of GIS spatial data structure has become mature and now people are paying more and more attention on the analysis based on GIS technology.This paper analyzes China＇s DEM data and vividly demonstrates the elevation of China＇s natural landscape,which is based on the highway natural zoning and GIS spatial analyzing model,laying the foundation for other parameters such as landform,hydrology,climate,vegetation and so on.The topic GIS system is implemented by using ArcObjects and VB.net.
