Design of GIS-based Real-time rainfall Analysis and Evaluation System

1. system architecture framework

The WebGIS-based Real-time rainfall Analysis and Evaluation System in Jiangsu adopts the Browse/server-based network structure mode supplemented by Client/Server. The B/S mode and C/S Mode complement each other, A networked geographic information system that combines map space information and attribute information. The system uses flex to write user interfaces, Tomcat-based, and Java technology to build server applicationsProgramThrough the spring3 Web Framework Program, request and obtain the database from the sysbase database and give feedback to the user in a timely manner. The system also uses the open-source map service engine geoserver to provide map data to the client. The biggest advantage of this map server is the ease and convenience of map production and map publishing operations during the development process, and the free open source has a hugeCommunityYes. At the same time, the system makes full use of network resources and also supports Google maps, and introduces topographic maps, traffic maps, and satellite maps. In this way, it complements the watermap released by geoserver and forms a powerful map service. The system uses the flex powerful interface expressive power call to perform spatial computing and frequency computing through the Java COM Service, and implements contour computing and frequency analysis computing based on WebGIS.
