AB  - This data set was acquired by airborne widas sensor on June 1, 2008 in Zhangye Yingke huazhaizi flight area. The original data is released after geometric correction, radiometric calibration and atmospheric correction. The data products for ordinary users are level-2c products (after geometric correction, radiometric calibration and atmospheric correction), as well as level-1b (inter band registration) quick view and level-2b (inter band registration) quick view. The original data (level-1a data) and data processing parameters are archived, which can be obtained only after the application is submitted and approved. The data processing time is from August 2008 to April 2009, and the completion time is April 2009. A correction of CCD camera radiometric calibration was made in November 2009. The original data of this data set includes 12 routes. Due to the unstable instrument state, some routes were re flown. The imaging time of 650nm and 750nm bands of the data CCD camera on that day has a deviation of about 1.4 seconds from that of 550nm and 700nm bands. It was registered in the preprocessing process, but there is still a certain degree of band registration error in the area with large elevation change.
