摘要
随着计算机技术特别是网络、通讯技术的发展,GIS技术得到了飞速发展,并朝着网络化、大众化的方向发展。同时,由于社会对地理信息的巨大需求,地理数据的应用日益广泛。但是空间数据中隐含着大量的知识信息与各类模式,因此,人们迫切需要一些有效的方法来从中提取出一些潜在的、有价值的知识。文中采用Visual C#.NET与ArcObjects相结合,开发出了空间缓冲区分析模块,实现了对空间缓冲区分析的功能,通过对其点、线、面的缓冲区分析,从而高效、直观地提取出隐含在空间数据中的信息。
With the development of computer technology, especially the network and communication technology, GlS technology has made rapid development, and developed in the direction of network and public. At the same time, because of the great demand for geographic information in the community, geographic data is widely used. But there have been increasing demands for efficient methods that extract rules and pattems from spatial data. This paper gets the module and foundations of spatial buffer analysis with Visual C#. NET and ArcObjects. After buffer analysed the points, lines, polygons, can get more potential information efficiently and intuitionisticly from the spatial data.
