城市地下管线多源数据整合研究

Integration Research for Urban Underground Pipeline Multi-source Data

地下管线数据质量的优劣直接影响城市管理的效率及规划决策的正确。本文阐述城市地下管线的多源数据特征,以苏州工业园区为例制定了数据标准,结合数据检查机制,解决了历史数据库中存在的数据问题。通过对GIS数据及CAD数据的转换模式研究,实现了新老系统的同步更新,对地下管线多源数据整合的研究有重要意义。

Underground pipeline data quality which is superior or inferior is directly affects the efficiency of urban management and planning decision‐making .It elaborate multi‐source data characteristics of urban underground pipeline .By the example of underground pipeline in Suzhou Industrial Park ,it set a data standards .And combining with data check mechanism ,it solve the problem of historical data exist in database .By the transformation mode research from GIS data to CAD data ,it implements system update from the old one to the new one ,which have important significance for underground pipeline of multi‐source data integration research .
