基于Web和IDL的气象观测数据图形显示研究

在分析C#和IDL通信机制的基础上,提出了基于IDL技术和Web技术的气象观测数据图形显示方式和实现机制。基于该图形显示方式,利用江西省87个国家气象观测站点数据,生成江西省年最高气温、最低气温、平均气温、降水量和日照时数等基本气象要素的空间分布图,图形曲线平滑,色彩丰富,能够真实反映各气象要素的空间分布特征。将该图形显示方法应用于Web系统开发中,实现了图形在浏览器端的实时显示,验证了该方法在实际项目应用中的适用性和可行性。

Research on the graphic visualization of meteorological observation data based on Web and IDL

. After analyzing the communication between C and IDL, a graphic display method andimplementation mechanism of meteorological observation data is proposed based on IDL and Webtechnology. The spatial distribution maps of basis meteorological elements like maximum temperature,minimum temperature,mean temperature, precipitation and sunshine hours from 87 national stationsare generated in Jiangxi province by using this graphic display method. The maps are rich in colors andthe curves are smooth. The spatial distribution characteristics of the meteorological elements can beshowed well in these maps. This graphic display method is applied to a Web system, and a real-timegraphical display in the browser side is achieved, which proves the applicability and feasibility of thismethod used in actual project application.
