极轨气象卫星资料的多维空间查询检索

The Multi-dimensional Spatial Retrieve of the Polar Orbital Meteorological Satellite Data

文章针对极轨气象卫星资料的时空分布特点,提出了对其进行数据处理、信息提取和建库的方法,并采用Ora-cle9i的空间数据技术,设计了从数据库中检索经过指定区域的卫星轨道资料的方法,解决了资料的多维空间查询检索问题。同时利用ISAPI编程接口和IDL可视化工具,实现了基于Web的区域投影图像生成、结果显示和数据下载。

According to the temporal-spatial characteristics of the polar orbital meteorological satellite data,a method of data processing,information extracting and database creating is presented.Also,a method of data retrieving is designed,which uses the spatial data option of Oracle 9i to solve the multi-dimensional spatial data retrieve problem.By using the ISAPI and IDL techniques,the regional image extracting,displaying and downloading on web is realized.
