基于ArcPy的城市排水管网GIS数据转换方法研究

Research on GIS Data Conversion Method of Urban Drainage Network Based on ArcPy

为方便、快捷地将排水管网探测数据库转换为能对排水管网属性、空间以及拓扑关系进行统一管理及信息共享的GIS地理空间数据库。本文采用ArcPy编程并创建地理处理工具对原始探测数据库中不同类型的排水设施进行分类,并根据不同类型排水设施创建不同地理要素,从而实现数据转换。该方法在昆明市某排水管线数据转换项目中得以成功实践,为今后数据转换提供了一种思路。

In order to conveniently and quickly transform the drainage network detection database into GIS geospatial database which can manage and share the attributes,space and topological relationship of drainage network.This paper uses ArcPy programming and creates a geographic processing tool to classify different types of drainage facilities in the original probe database,and creates different geographic elements according to different types of drainage facilities,so as to realize data conversion.This method has been successfully applied in a drainage pipeline data conversion project in Kunming,which provides a way of thinking for data conversion in the future.
