| 摘 要： | NOAAAVHRR提供的1B数据，是以一个文件存储图像数据和相关的辅助数据，目前的商用遥感图像处理软件大多无法直接读取与图像有关的定标、定位、太阳与传感器位置等数据，对图像的后续定量化处理与应用带来了困难。本文在深入分析1B数据格式的基础上，实现了基于ENV~IDL平台的1B格式数据读取与预处理模块开发，这对于AVHRR图像数据的应用具有重要的现实意义。

| Abstract: | NOAA AVHRR provides us original lb data format, which stores image data and associated ancillary data in the same file. But current commercial remote sensing image processing software system cannot read out the related information about image calibra- ting, positioning, the sensor location and other data, so it has brought great difficulties to subsequent image processing and applica- tion. Based on the analysis of the 1 B data format, this paper developed the reading and processing module from the raw data based on ENVI / IDL platform. It is of great practical significance for the application of AVHRR image data. |
