DIGITAL CAMERA SYSTEM
The Digital Camera System (DCS) is an airborne digital camera that acquires high resolution natural color and panchromatic imagery from low and medium altitude research aircraft. Data acquired by DCS are used by a variety of scientific programs to monitor variation in environmental conditions, assess global change, and respond to natural disasters.
