TJ_CS_Hyperspectral

We employed Hexacopter unmanned aerial vehicle (UAV) equipped with the SPECIM FX17E hyperspectral camera to implement ultra-low-altitude flight aerial photography missions with atmospheric correction processing. We collected three hyperspectral images and combined them into three data pairs, which exhibit varying degrees of spectral shift. Among them, a hyperspectral image including six types of ground objects was collected in Changsha at 4:00 pm on September 27, 2021, with sunny weather and a flight altitude of 30m, named CSSunny. Besides, we captured two hyperspectral images in Tianjin, both of them contain twelve types of ground objects and the flight altitude was 60m. One of them was shot at 3:00 pm on March 21, 2023, with sunny weather, and the other was shot at 3:30 pm on March 22, 2023, with cloudy weather, named TJSunny and TJCloudy respectively. The spatial resolution of three images in the self-collected data pairs is 482 × 640, and the spectral wavelength of them ranges from 935nm to 1720nm with 224 bands.
