Research On The Information Retrieval System Of Power Grid And Typhoon Based On WebGIS

Typhoon is one of the most destructive disasters in nature. PowerGrid of Fujian province is suffering from typhoon. With the development of science and technology, the method for studying and analyzing data is improved. So we are eager to seek a better way to manage, analyze typhoon data and PowerGrid data. Recently, with the extensive applications of GIS in various fields, WebGIS becomes widespread. It proves WebGIS is a highly effective approach of data management and analysis.This thesis introduces the information system of typhoon and PowerGrid is based on WebGIS. It is not only satisfied with the integration of power grid and typhoon monitoring information,but also according to business need,integrated the new functions.This thesis firstly analyzes the significance and the background of this project;and introduces the development,application,study status of WebGIS. This 2,3 chapters of this thesis introduce domestic WebGIS platform-GeoSurf. and the function design and database design of PowerGrid and typhoon information system. This thesis introduces the technologies of attribute list query and the realization of WebGIS. At last, as for the status of this system,we give some suggestions in order to make the system perfect. It points out that wo make efforts in the direction.
