THEMATIC MAPPING OF FLOODED ACREAGE

A PRACTICAL TECHNIQUE FOR EXTRACTING PHOTOMETRIC INFORMATION BY CRITICAL ANALYSIS OF SCENE SHADOW IMAGES HAS PREVIOUSLY BEEN INTRODUCED-THAT OF THE SCENE COLOR STANDARD (SCS) TECHNIQUE. THIS PAPER CONSIDERS FURTHER DETAILS OF THE SCS TECHNIQUE, AND PROVIDES AN EXAMPLE OF THE ENHANCEMENT AND INTERPRETATION OF PHOTOMETRIC IMAGE DATA IN THEMATIC MAPPING OF FLOODED ACREAGE. MAPPING IS ACCOMPLISHED BY NOTING THAT VEGETATION, SOIL, AND WATER CLASSES CAN BE DELINEATED BY A RATIO OF THEIR REFLECTANCE IN THE INGRARED AND GREEN BANDS. AN APPROXIMATE MAP OF REFLECTANCE RATIOS WHICH ENHANCES THESE TERRAIN CLASSES FOR THE INTERPRETER CAN EASILY GENERATED FROM THE PHOTOGRAPHIC IMAGE. AN EXAMPLE OF THE USE OF THIS TECHNIQUE CONSISTS OF THE SUCCESSFUL DISCRIMINATION OF FLOODING CONDITIONS OF THE MISSISSIPPI RIVER NEAR VICKSBURG FROM AN APOLLO 9 PHOTOGRAPH. /AUTHOR/
