Application Research Of Visual Management Information System Of Hydropower Station Group Based On WebGIS

Data model ,data structure, data storage ,and realization methods of WebGIS is researched in this paper with researching ,designing ,and applying visual management information system(MIS) of hydropower station Group. In order to solve the problem of data share and exchange between Distributed Database (DDB) and WebGIS, Agent method is introduced and Agent based structure design scheme of WebGIS is presented. At last, an open, easy to operate and expend Management Information System of Hydropower Stations Group is developed as an application example. The MIS of Hydropower Station Group based on WebGIS mentioned above is based on practical manufacture operation and application, and builds integrated information share platform with functions of zoom and cruise of electric map and query of images and words. By taking full advantage management mechanism of Relational Data Base Management System (RDBMS), common management of spatial and non-spatial data is realized, simultaneously, difference of data platform is weakened and flexibility and extensibility of the system is enhanced without change of existent system; In this system, the problem of data share and exchange between DDB and WEBGIS is resolved and the visual query and monitoring of real-time data of remote user is realized; The system supply the way of acquisition of operation information, and the publish and share of visual operation information of multi-platform and multi-region is realized in this system.
