Water strongly absorbs mid-infrared (1300-2500 nm) radiation, resulting in this region of the spectrum being sensitive to the water content within features. Little information is available on using an electronic digital camera filtered to this region of the spectrum to assess natural resources. The objectives of this study were to assemble an electronic digital camera system obtaining mid-infrared imagery and to show practical applications of the system for assessing natural resources. The system consists of a near-infrared to mid-infrared light sensitive camera (900-1700 nm, 14-bit radiometric resolution) containing a 640 by 512 indium gallium arsenide area array, a computer, an image acquisition card, a camera-link cable, a keyboard, a color monitor, a camera tripod, a generator, a camera mount, and a mid-infrared narrow bandpass filter (1632-1648 nm). The components of the system allow users to obtain ground or airborne imagery. Ground-based imagery and data were useful for separating succulent from nonsucculent plant parts. Airborne imagery provided useful information for differentiating vegetation, soil, and water and for identifying management practices such as irrigation. Findings of this study indicate that an electronic digital camera filtered to the mid-infrared region of the optical spectrum has high potential for assessing natural resources.
