Traditional coastal zone surveys rely on regular time consuming methods to obtain discrete sets of data to record changes in coast profiles. Drone surveys cover large and often inaccessible areas safely and rapidly in order to provide overlapping fine detail geo-referenced images which give 100% coverage of the landscape. These images are processed to produce ortho-mosaics (rectified images corrected for camera angle, terrain relief, and lens distortion) for input into a GIS database.
