城市排水GIS数据分析与组织

Analysis and Organization of Data in GIS-based Urban Drainage Pipe System

建立城市排水管网信息系统,目的在于应用信息化工具提高排水管网管理效率;对其数据的分析和组织是保障该信息系统顺利工作的基础。从内外两方面分析排水管网管理要素,提出了排水管网地理信息系统对象设置、图层组织、数据编码方案,并以实例进行说明。

The Urban Drainage Pipe Network Information System is established to improve the management of the drainage pipe network in efficiency. And the preconditions of the system are the analysis and organization of the data about the pipe network. The paper outlines the elements of the management inside and outside the pipe network, and then suggests a project involving the organization of objects, layers and codes.
