Sierra Arana sinkholes cartography (Granada, Spain)
This picture was taken at an altitude of about 6000m by a balloon-based UAV called "Stratochip". The Stratochip is fully autonomous and can travel tens to hundredths of miles while taking pictures of the ground from different angles, with its orientable camera. This flight aimed at the cartography (orthomosaics and DEM reconstruction by Structure-from-Motion) of a karstic field (sinkholes in the upper-left side of the picture) forming in the Jurassic carbonates formations of the Sierra Arana mountain range, Granada region.
