AIR PHOTO ANALYSIS OF INFRARED COLOR PHOTOGRAPHY

AIR PHOTO ANALYSIS OF INFRARED COLOR PHOTOGRAPHY IS CONTRASTED WITH BLACK AND WHITE PANCHROMATIC AND NORMAL COLOR PHOTOGRAPHY AS A MEANS FOR ASSESSING THE PHYSICAL PROPERTIES OF SOILS AND BEDROCK FOR HIGHWAY DESIGN, CONSTRUCTION, AND MAINTENANCE. TWO METHODS OF MAPPING WERE EXPLORED. THE FIRST METHOD IS PROBLEM ORIENTED AND IS DESCRIBED IN A MANUAL ENTITLED "MANUAL OF HIGHWAY-PROBLEM-ORIENTED PHOTO INTERPRETATION USING PANCHROMATIC, NORMAL COLOR, AND INFRARED COLOR AIR PHOTOS" WHICH SUPPLEMENTS THE REPORT. THE SECOND MAPPING METHOD IS CALLED "RECONNAISSANCE MAPPING" AND RESULTS IN MAP UNITS WITH A FIVE-PART SYMBOL: (1) LAND FORM, (2) SOIL TEXTURE, (3) SURFACE SLOPE, (4) WATER TABLE POSITION, AND (5) DEPTH OF SOIL TO BEDROCK. SPECIAL SYMBOLS ARE ADDED FOR COORDINATING EXPLORATORY DRILLING. THE MAP IS INTERPRETATIVE, CONTAINING INFORMATION LIMITED TO A ROUTE CORRIDOR. A STATISTICAL STUDY ATTEMPTS TO DETERMINE THE SUCCESS WITH WHICH INTERPRETERS CAN OBSERVE AND EVALUATE PERTINENT PARAMETERS AND RANK THEM IN GROUPS AMENABLE TO ANALYSIS. THESE PARAMETERS ARE THEN USED TO COMPARE THE CAPABILITIES OF THE THREE FILM TYPES. SEVERAL USEFUL STATISTICAL TESTS ARE DEMONSTRATED. THE EVALUATION BY STATISTICAL MEANS OF ALL PARAMETERS USED IN INTERPRETATION WAS NOT DEMONSTRATED. THE PROBLEM- ORIENTED TYPE OF MAPPING IS RECOMMENDED. RECONNAISSANCE MAPPING IS SUCCESSFUL IN PENNSYLVANIA EXCEPTING THOSE AREAS OF COMPLEX IGNEOUS AND METAMORPHIC ROCKS IN THE SOUTHEAST. /AUTHOR/
