DIGITAL CORRECTION FOR HIGH-RESOLUTION IMAGES

AN EFFICIENT, HIGH-SPEED ALGORITHM FOR APPLYING GEOMETRIC CORRECTIONS TO HIGH-RESOLUTION IMAGES HAS BEEN DEVELOPED AND IMPLEMENTED AS A DIGITAL COMPUTER PROGRAM. THIS ALGORITHM WAS APPLIED TO TWO IMAGES REPRESENTATIVE OF THOSE TO BE GENERATED BY THE RETURN BEAM VIDICON WHICH WILL BE USED DURING THE EARTH RESOURCES TECHNOLOGY SATELLITE PROGRAM. PROCESSING OF EACH IMAGE REQUIRED ONLY 80 SECONDS OF CPU TIME AND 450 KILOBYTES OF MEMORY ON AN IBM SYSTEM/ 360 MODEL 65. IN A COMPANION EXPERIMENT USING THE SAME TWO IMAGES, A SIMPLE "SHADOW CASTING" TECHNIQUE FOR DETECTING AND LOCATING RESEAUMARKS IN THE RBV DATA WAS FOUND TO BE QUITE ADEQUATE FOR SUPPORT OF THE GEOMETRIC CORRECTION PROCESS.
