MULTISPECTRAL COLOR AGRICULTURE AND FORESTRY

THE POTENTIAL USEFULNESS OF MULTISPECTRAL COLOR PHOTOGRAPHY FOR THE IDENTIFICATION OF CROP AND TREE SPECIES HAS BEEN DEMONSTRATED IN A SERIES OF CONTROLLED EXPERIMENTS USING BROAD-BAND CAMERA FILTERS WHICH APPROXIMATE THE SPECTRAL SENSITIVELITY OF COLOR-INFRARED FILMS. INDEPENDENT ADJUSTMENT OF EXPOSURE IN EACH CAMERA BAND, CONTROL OVER THE GAMMA AND DENSITY OF THE PHOTOGRAPHIC IMAGE, ALONG WITH THE ABILITY TO ADJUST THE HUE, BRIGHTNESS, AND SATURATION IN VIEWING, RESULTED IN GREATER IMAGE CHROMATIC SEPARATION THAN COULD BE ACHIEVED USING SUBTRACTIVE COLOR REVERSAL FILMS. THE CAPABILITY TO COMPENSATE FOR VARIATIONS IN THE SOLAR ILLUMINANT AND ATMOSPHERIC ATTENUATION USING ADDITIVE COLOR VIEWING OF MULTISPECTRAL PHOTOGRAPHS WAS DEMONSTRATED. /AUTHOR/
