MULTISPECTRAL PHOTOGRAPHIC DETERMINATION OF REFLECTANCE

AERIAL SPECTRAL PHOTOGRAPHS WERE ANALYZED TO OBTAIN THE SPECTRAL REFLECTANCE OF ENVIRONMENTAL FEATURES. THE EXPERIMENTAL AND ANALYTICAL TECHNIQUES USED TO OBTAIN REFLECTANCE VALUES WITH STANDARD DEVIATIONS OF THE ORDER OF 7 PERCENT ARE DISCUSSED. PARTICULAR EMPHASIS IS PLACED ON THE USE OF CALIBRATED GROUND CONTROL PANELS TO REMOVE THE EFFECTS OF ATMOSPHERIC SCATTERING FROM THE REFLECTANCE DETERMINATIONS. THE EFFECTS OF SYSTEM RESOLUTION ARE PRESENTED AS A PART OF THE ACCURACY DISCUSSION BECAUSE RESOLUTION EFFECTS ALTER THE REFLECTANCE VALUES. THIS ALTERATION IS DUE TO THE INCLUSIONS OF SHADOW AND THE MIXING OF DIFFERENT ENVIRONMENTAL FEATURES WITHIN THE GROUND RESOLUTION ELEMENT. THE AVERAGING CAUSED BY RESOLUTION MAY DETERMINE THE LIMITS OF THE DETECTABILITY OF SUBTLE DIFFERENCES IN PRACTICAL APPLICATION, SUCH AS THE STUDY OF EARTH RESOURCES FROM A SATELLITE (EROS PROGRAM). /PE/
