基于WebGIS的地下管网综合管理系统关键技术研究

设计并开发了基于WebGIS的地下管网综合管理系统,重点从二维管网数据的组织、存储、分析、更新等方面进行研究:采用ArcGIS作为系统的基础GIS平台;采用Python语言进行二维数据的预处理;采用Model Builder完成爆管分析、流向分析等网络分析功能;采用OGC的WFS服务为数据更新提供支持;采用JavaScript、Asp.net语言构建WebGIS系统平台,最终实现了各项查询、统计、分析、应急等功能模块,并且在Web浏览器上进行二三维联动算法研究,解决了二维系统中不能精确直观地描述管线三维立体信息的问题,实现了真正的二三维一体化系统,从而为各权属和业务部门科学高效管理和有效决策提供辅助支持。

Research on Key Technologies of Integrated Management System of Underground Pipeline Network Based on WebGIS

This paper designs and develops an integrated management system of underground pipeline network based on WebGIS,focusing on the organization,storage,analysis and update of two-dimensional pipeline network data.ArcGIS is used as the basic GIS platform of the system;Python language is used to preprocess two-dimensional data;Model Builder is used to complete network analysis functions such as tube burst analysis and flow direction analysis;WFS service of OGC is used to support data updating;JavaScript and Asp.net language are used to build WebGIS system platform,which is finally realized.Various query,statistics,analysis,emergency and other functional modules,and in the Web browser for two-dimensional and three-dimensional linkage algorithm research,solve the two-dimensional system can not accurately and intuitively describe the three-dimensional information of pipelines,to achieve a real two-dimensional and three-dimensional integration system.Thus,it can provide assistant support for scientific and efficient management and effective decision-making of each ownership and business department.
