TY - Data T1 - Heihe integrated remote sensing joint test: Observatory Zhangye flight area airborne widas data set (June 29, 2008) A1 - Liu qiang A1 - Xiao qing A1 - Li xin A1 - Ma mingguo DO - 10.12072/ncdc.NIEER.db1734.2022 PY - 2021 DA - 2021-09-14 PB - National Cryosphere Desert Data Center AB - The data set was acquired by airborne widas sensor on June 29, 2008 at the observatory Zhangye 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.
