[目的]设计并实现一种沼气工程地理信息系统。[方法]在对北京市大中型沼气工程充分调查后获得数据的基础上,分析系统用户需求和功能需求,划分子系统功能,使用SuperMap IS.NET和C#语言编程技术,采用WebGIS架构,设计了系统空间和属性数据库,实现了以北京市为例的沼气工程WebGIS系统。[结果]该系统为沼气工程信息的网络发布提供了应用平台。用户可根据系统使用权限实现沼气工程信息的反馈提交和查询等,能更直观、全面、准确地查询工程数据,对数据进行综合分析,从而对沼气工程的现状和变化趋势进行研究和决策。[结论]该系统为相关管理部门对沼气工程的规划管理工作提供了便利服务。
[Objective] To design and implement a biogas engineering geographic information system. [Method] Based on the data obtained after full investigation of large and medium-sized biogas project in Beijing, the system user needs and functional requirements were analyzed and the subsystem functions were divided. Using SuperMap IS.NET and C # language programming techniques, the WebGIS architecture was used to design System space and attribute database to realize the biogas project WebGIS system taking Beijing as an example. [Result] The system provided the application platform for the web publishing of biogas project information. The user can submit feedback and query of biogas project information according to the system usage right, and can query project data more intuitively, comprehensively and accurately and make comprehensive analysis on the data so as to research and make decisions on the status quo and trend of the biogas project. [Conclusion] The system provided the convenient service for the related management department on the planning management of biogas project.
