摘要
以安徽省地理信息公共服务平台数据融合为例,分析了省级节点与国家主节点的数据源优缺点,制定了切实可行的数据融合技术路线与融合方法,对融合中的关键技术进行了研究,并提出了相应的处理方法,为我省今后全面开展省市数据融合奠定了良好的技术基础。通过数据融合,提高了数据的现势性、丰富了数据的内容,为安徽省地理信息服务提供了坚实的数据基础。
Taking the data fusion of geographical information public service platform in Anhui Province for example,we established a technical route and method of data fusion based on the analysis of the advantages and disadvantages about the data source between Anhui Province and the main code.Then,we studied the key technologies in data fusion,and proposed some corresponding processing methods,which could establish a good technical foundation for the data fusion of Anhui Province in the future.The data fusion can not only improves the present situation of data,but also enriches the data content,which can provide a solid data base for geographical information service of Anhui Province.
