摘要
以松嫩平原湿地的保护为背景,提出了基于GIS的湿地信息系统的建立方法。用GIS-GPS相结合的方法进行空间数据控制点的设置,克服了传统控制点设置方法的局限性;同时,应用VB+ArcObjects技术进行系统实现,并对叠加分析、空间检索等关键技术的实现方法进行了探讨。
This paper puts forward a kind of designing method of wetland information system based on GIS with protecting wetlands in the background. GIS-GPS method is presented to setup control point for spatial data, which overcomes localization of traditional method. And at the same time, it applies VB+ArcObjects technology to realize information system, and discusses some important techniques such as intersect analysis spatial searches and so on.
