The Design And Implement For Water Supply Geographic Information Network System Of Xiamen Municipal

With the development of science and technology,GIS technology in various sectors has been widely used,and achieved good results in the application of geographic information management.This study is based on the application of this background,the Xiamen Municipal water supply network based on GIS geographic information system to conduct a comprehensive analysis and design. Which in the course of this study,the first theory for information management,GIS pictures in-depth analysis and discussion. Laid the theoretical foundation for the research of this article. In addition,the demand for effective management of the water supply network in Xiamen, designed to develop data management module,management module view,query retrieval module,incident handling module and system settings and other functional modules.Use case diagram of the way with the use cases for each system module is analyzed in the system design phase,the thesis carried on the overall architecture of the system on the basis of design,build targeted herein function module design situations are discussed, the use of timing Diagram manner module operation timing conditions are described, and the case for GIS data on the back-end database structure of the system is analyzed and design. In the system implementation phase,we use Delphi language and SQL 2008 database technology for system functions were implemented effectively to achieve the main function modules GIS-based water supply network in Xiamen City of geographic information systems, and to achieve the effect of module were demonstrated,given the core processing code system critical module.And to achieve the effect modules were tested. Further research work is completed.Through this study,the use of the design and development of the water supply network of a geographic information system of water management in line with the actual needs,and through GIS technology,the entire water supply of official inquiries and quickly locate information. Improve the overall efficiency of the water sector management.
