Testing Aerial Digital Cameras

摘要

Aerial imaging for mapping purposes is increasingly done using digital cameras. The introduction of new models brings a steady rise in pixel volume, enabling wider swath width and thus reductions in flight line, flight costs and project risks, or data acquisition with larger ground-sample distances (GSD), preserving efficiency. Full exploitation of larger GSD depends on geometrical accuracy, dynamic range, image sharpness and storage device. The author tested these four features of two UltraCam systems: the Xp and L.
