Disgrifiad

Digital imagery acquired by a Sony NEX-5N digital camera vertically mounted inside a fixed-wing UAV. The UAV surveyed a 25 km east-west transect dissecting the dark zone of the K-sector of the Greenland Ice Sheet on 8 August 2014. The camera has a 16 mm fixed focus lens (53.1 by 73.7° field of view) yielding an image footprint of approximately 525 x 350 m during the autonomous sortie. The camera was preset with a fixed shutter speed of 1/1000 s, ISO 100 and F-stop of 8. The images have a pixel footprint of approximately 11 cm. A corresponding csv file provides the UAV geolocation and attitude data for each image. The data were logged by an Arduino navigation and flight computer in real-time by a 10 Hz data stream comprising of a GPS, magnetometer, barometer and accelerometer.
