多源矢量道路匹配方法研究

Research on Multi-source Vector Road Data Matching

地理信息服务的基础是数据,要求数据现势性强,信息可靠。随着经济、科技的发展,地理数据的获取方式越来越丰富,卫星遥感、GPS等等都已经成为获取数据的技术手段。基于此,本文根据生产中的实际需要,探讨了矢量道路的匹配方法,并将其分为同源和非同源数据进行分类研究,作为道路变化检测的基础。最后根据研究方法予以实验,验证其有效性。

Basic geographic data which is the basic of geographic information services must have high potential and reliability.With the development of economy,science and technology,there are more and more methods to obtain geographic data,such as satellite remote sensing,GPS,etc.Therefore,this paper discusses the method of vector road data matching,according to the actual needs of production.The research divides vector roads into homologous and non-homologous data.The results will be a basis for the changing road detection research.Finally,the proposed method is the proven to be effective by an experiment.
