基于GIS的水调信息动态分析查询系统设计及实现

Design and Implementation of Reservoir Scheduling Information Dynamic Analysis and Query System Based on GIS

地理信息系统(GIS)技术已在水调自动化领域得到了广泛应用。文中拓展了原有水调GIS应用,不仅实现了水调信息的实时动态监视、历史数据查询等基本功能,同时实现了雨量等值线填色图生成、填色图及分区面雨量动态演进、任意区域面积量算、面雨量及水量统计等空间分析统计功能。阐述了系统设计及实现难点,重点介绍了系统关键技术。

GIS technology has been widely used in reservoir scheduling automation area.This study extends the existing waterpower scheduling GIS application.It realized not only basic functions such as： reservoir scheduling information real-time dynamics monitoring,historical data query,etc.,but also functions such as： forming rainfall contour map generated coloring,coloring maps and dynamic evolution of regional surface rainfall,random regional area calculation,regional rainfall and surface water statistics,and other spatial analysis statistical functions.Finally,the system design and implementation difficulties,and highlights key technology system are described in the paper.
