| 摘 要： | 本文在外部数据交换基础上,提出基于空间ETL的数据交换共享方式。采用VCT格式作为统一的数据交换格式,结合ETL数据流动的思想,对数据进行处理。本文以Geodatabase到VCT的相互转换为例,采用ArcGIS组件开发,从而实现GIS空间数据的交换共享。

| Abstract: | On the foundation of exterior data exchange,the paper proposed the way of data exchange sharing based on the spatial ETL.Taking VCT as the unified data exchange format,combining with the thought of ETL data transition,the paper carried out data processing.Taking the interconversion from Geodatabase to VCT as example,the paper developed with ArcGIS module to implement the GIS spatial data exchange sharing. |
