基于GIS的城市排水管网设施管理系统

摘要

以GIS为技术支持，结合排水管网设施管理的实际需求建立了排水管网设施管理系统。借助ArcGIS平台，充分发挥了GIS在可视化，查询定位及空间数据管理等方面的优势，实现了普查数据的入库以及设施数据管理功能。并在此基础上构建了排水管网网络模型，借助模型实现了管网流向、连通性、污染源追踪、污染影响范围等网络分析功能。%For technical support with GIS, combined with the actual needs of the drainage facilities management to establish a management system.
