利用FME的小城镇规划数据集成方法

多源数据集成和共享是实现区域规划的瓶颈问题。本文提出利用XDATA扩展数据的方法满足信息量需求,并针对数据集成过程中要素丢失等现象,编写VBA代码实现源数据的质量控制;提出利用FME重新定义数据以实现多源数据的语义转换和集成数据字典模式统一数据编码的数据集成方法。研究表明,该方法符合数字化、信息化测绘和管理数据的发展要求,能够提高数据生产和应用的效率,是一种实用且值得推广的方法。

Town planning data integration methods based on FME

Multi-source data integration and sharing are the bottleneck of regional planning.This paper proposed using the XDATA extending data method to meet the information demand.In consideration of the phenomenon such as elements lost in the process of data integration,it programmed VBA codes to achieve the data quality control.Meanwhile,it suggested using FME redefine data methods to converse semantics,and using the integrated data dictionary to unify data codes.Research showed that the method could accord with the development requirements of digital,information survey and data management,and improve the efficiency of data production and application.Therefore,it would be a practical method and deserve popularization.
