介绍了极轨气象卫星局地投影文件的结构,并在ENVI环境下,通过简单的IDL程序开发,自动批量处理LD2/LDF头文件,其数据可供ENVI软件直接读写和处理,避免了繁琐的手工配置,为进行其他数据格式转化和产品开发提供了前提条件。
This paper introduces the structure of local projection file of polar orbit meteorological satellite and automatically batch-processes LD2 / LDF header files in ENVI environment through simple IDL program development. The data can be directly read and written by ENVI software and processed, avoiding the cumbersome The manual configuration provides the preconditions for other data format conversions and product development.
