摘要
分析了产业用地源数据,阐述了数据整合前标准制定的,同时介绍了数据整合的技术路线和方法。根据产业用地数据多源异构性等特点,以ETL技术框架为基础,对数据进行抽取、转换、清洗和装载,并利用ArcCatalog对经济普查数据进行装载将其和空间数据相连接。最后从数据质量控制出发,提出数据整合中注意的事项。
Industrial land source data is analyzed. And how to establish standard in data integration is elaborated. At the same time, the routes and methods of data integration tech-nology are introduced. According to the multi-source heterogeneous characteristics of industry-ial land data, the data is processed in extraction, conversion, cleaning and load- ing based on the framework of ETL technology. Furthermore, ArcCatalog is utilized to load the general data and join it with the spatial data. Finally, some precautions in the industrial land data integration are proposed from quality control purposes.
