%X This dataset contains (1) Gansu Zhangye CASI + Sasi aerial remote sensing data processing （2）Process of the airborne data_ CASI+SASI On June 29, 2012 and July 7, 2012, in the 30 * 30km core observation area and the midstream sample zone in the middle reaches of Heihe River, the flight test of obtaining visible / near-infrared short wave infrared hyperspectral aerial remote sensing data was carried out by using Yun 12 aircraft and CASI / Sasi sensors. The relative flight altitude is 2000 meters (altitude is 3500 meters). The wavelength ranges of CASI and Sasi sensors are 380-1050 nm and 950-2450 nm respectively, and the spatial resolution is 1 meter and 2.4 meters respectively. The surface reflectance product is obtained by using the synchronously measured ground data and atmospheric data through geometric and 6S atmospheric correction
