基于GIS的自动气象站实时资料空间展示方法研究

Research on Method of Automatic Weather Station Real-time Data Spatial Display Based on GIS

气象自动站数据准确度高、时间和空间分辨率强,但在当前预报应用中表现形式相对单一,传统气象数据处理手段无法有效、实时直观展示气象数据的时间与空间特性,导致自动站数据的利用受到了一定的限制。为发挥自动站数据的时空优势,通过使用GIS在空间数据管理和分析上的强大功能,实现自动站数据实时显示、气象要素查询结果 GIS可视化表达等功能,为自动站数据提供一个稳定、方便、快捷的数据平台,提高气象业务工作效率。该系统已在上海市嘉定区气象局业务中得到应用,明显提升了气象数据的运用水平。

Although the automatic weather station data has high precision and strong space-time resolution, but it＇ s expression is simple in current forecast application and the traditional meteorological data processing method can＇ t express the spatial character of automatic meteorological station data effectively and real-time intuitively, the availability of automatic weather station data is restrictive. In order to play the space-time advantage of the automatic weather station data, using the powerful capabilities of GIS in spatial data management and analysis can realize the real-time display of automatic weather station and GIS visualization expression of meteorological elements of query results and so on. It provides a stable, fast and convenient data platform and improves the efficiency of the meteorological operations. The GIS system has been applied in Jiading meteorological administration in Shanghai, significantly enhanced the level of use of meteorological data.
