COASTAL AND URBAN SURVEYS WITH IR

REMOTE-SENSING RESEARCH IS DESCRIBED AT THE UNIVERSITY OF HAWAII INVOLVING REAL-TIME IMAGERY OF THERMAL ANOMALIES WITH AN AIRBORNE SCANNER. THE MAIN EFFORT WAS DIRECTED TO A STUDY AND DEVELOPMENT OF TECHNIQUES IN GEOPHYSICAL EXPLORATION FOR WATER-RESOURCES RESEARCH UTILIZING THE 3 TO 5.5 MICROMETER BAND OF INFRARED REAL-TIME IMAGERY. AN INFRARED SCANNER COVERING THE 2 TO 5-MICROMETER WAVELENGTH REGION WAS FLOWN OVER THE COASTLINE OF THE PUNA AND KAU DISTRICTS ON THE ISLAND OF HAWAII. ONLY A 5 X 5 DEGREE LENS (NARROW-ANGLE) WAS AVAILABLE, HENCE THE FLIGHT LINE HAD TO BE AT AN ALTITUDE OF 11,000 FEET IN ORDER TO MAKE EACH IMAGE ABOUT 1100 FEET ON A SIDE. A FEW AREAS WERE MOSAICKED AND MOUNTED ON AERIAL PHOTOGRAPHS TO FACILITATE INTERPRETATION. THERMAL ANOMALIES WERE EASILY IDENTIFIABLE ON EARLY MORNING IMAGES, BUT NOT DURING MIDDAY HOURS, AS NO FILTER WAS USED. /PE/
