APPLICATION OF RADAR IMAGERY TO DRAINAGE ANALYSIS

THIS STUDY IS BASED ON COMPARISON OF DRAINAGE-BASIN DATA FROM IMAGERY FROM A K-BAND IMAGING SYSTEM AND FROM TOPOGRAPHIC MAPS AT THE SCALE OF 1:24,000. FOR MAPPING PURPOSES THE PRESENTATION OF STREAM NETWORKS ON THE RADAR IMAGERY WAS GOOD FOR LOW-ORDER STREAMS, BUT DETAIL WAS LOST FOR FIRST-ORDER STREAMS. FOR ANALYZING DRAINAGE STREAMS, PARAMETERS DERIVED FROM THE IMAGERY INCLUDED NUMBERS AND LENGTHS OF STREAMS, AREAS OF BASINS AND REGIONAL SLOPES. THIS IMAGERY WAS ALSO BETTER FOR SECOND-ORDER OR HIGHER STREAMS. FOR DRAINAGE-BASEIN ANALYSIS, RADAR IMAGERY IS ESPECIALLY PROMISING FOR COVERING LARGE AREAS. AT PRESENT, STREAM DATA ARE OBTAINED FROM RADAR IMAGERY MANUALLY, BUT SCANNING METHODS CAN NOW ANALYZE DRAINAGE BASINS QUATITATIVELY AND COVERT DATA DIRECTLY TO A MAP EQUIVALENT. THIS EDGE-ENCHANCEMENT METHOD IS OF VALUE IN OBTAINING TOTAL LENGTH OF STREAM NETWORKS. /GA/
