Data Collection

Data collection can be accomplished using any small UAS capable of capturing nadir (vertical) mapping images.  Imagery can also be collected via manned aircraft as long as GSD (resolution) works out to 10cm per pixel or less.  Higher resolution imagery and products will result in higher output accuracy from the CLARKE system.
