NASA Coffee Harvest Demo Validates Practicality of UAVs

In this 32 second video, NASA's solar-powered Pathfinder-Plus photographs Hawaiian coffee fields and the results are analyzed.

Sensitive infrared and visible light cameras mounted in small pods underneath the craft's center wing recorded crisp digital images of the ripening coffee fields from the aircraft flying four miles above, and immediately relayed that imagery to the ground. Based upon that imagery, plantation managers were able to determine which fields were most appropriate for harvest.
