基于GIS组件开发的水利工程管理系统研究

Study on Water Resources Project Management Information System based on GIS Components

针对水利工程管理系统开发中GIS应用需求特点,比较了现有GIS开发技术,选择组件式GIS开发方案,采用B/S体系结构。详细分析了WebGIS的计算模型、主要实现方法和应用框架。通过南通市水利工程管理信息系统开发的实际应用,说明利用GIS组件实现水利工程空间数据处理、分析、显示功能,并与应用系统进行有机集成,可为水利工程管理业务基于WebGIS的开发探索出一种可行的开发方案。

According to requirement features of applying GIS in system development of water resources project management information system （hereinafter referred to as MIS）, by comparing existing GIS development technology, component GIS and B/S architecture are selected to this application method. This paper makes a detailed analysis on calculation model, main realization methods and application framework of WebGIS. The actual development of water resources project MIS in Nantong has shown that GIS component has realized system functions of spiral data processing, analysis, display for water conservancy project, and also can be integrated with the application system, which can seek out a kind of feasible development scheme for water resources project management services based on WebGIS.
