WebThe relative positions of the centers of the six cameras’ CMOS and the phase center of the onboard D-RTK antenna have been calibrated and are recorded in the EXIF data of each image. Mapping Functions Ground Sample Distance (GSD) (H/18.9) cm/pixel, H indicates the aircraft altitude relative to the area mapped (unit: m) Rate of Data Collection WebMay 25, 2024 · Ground Sample Distance. When it comes to drone surveying, ground sample distance - or GSD - is another important factor. GSD is a calculation used to explain how the real world scale established by GCPs translates to a map. The GSD describes the distance between the centre point of two consecutive pixels on a digital image.
