Satellite

Through the cooperation of the Naval Research Lab, GeoEye and DigitalGlobe, three satellites were able to capture scenes of the Avon ground truth site throughout the day of the experiment. The three satellites: WorldView 2, GeoEye-1, and HICO all collected a single image of the site during the day. These images have much larger GSDs and were taken while people were working in the field, offering some interesting unknown targets.
