REMOTE SENSING AND DEVELOPMENT OF ANNOTATED AERIAL PHOTOGRAPHS AS MASTER SOIL PLANS FOR PROPOSED HIGHWAYS

TWO COMPREHENSIVE STUDIES WERE MADE AT PURDUE UNIVERSITY ON THE APPLICATION OF REMOTE SENSING SYSTEMS TO THE DEVELOPMENT OF MASTER ENGINEERING SOIL PLANS. THE REMOTE SENSING SYSTEMS EVALUATED IN THE COURSE OF THIS RESEARCH CONSISTED OF AERIAL PHOTOGRAPHY, INFRARED IMAGERY, SIDE-LOOKING AIRBORNE RADAR IMAGERY AND MULTISPECTRAL IMAGERY. THE MULTISPECTRAL ANALOG DATA WERE USED IN CONJUNCTION WITH A DIGITAL COMPUTER TO SEMI-AUTOMATICALLY PRODUCE THEMATIC MAPS AND STATISTICAL ANALYSIS OF REFLECTANCE OF SURFACES. INFERENCE TECHNIQUES WERE USED TO EVALUATE THE PHOTOGRAPHY AND IMAGERY. IT IS CONCLUDED THAT IN AREAS OF LOW RELIEF (300 FEET OR LESS) A COLOR AERIAL PHOTOGRAPHIC MOSAIC PROPERLY ANNOTATED IS AN EXCELLENT MASTER ENGINEERING SOIL PLAN. AN ANNOTATED BLACK AND WHITE MOSAIC IS ALSO GOOD BUT IT IS NOT AS COMPLETE AS A COLOR MOSAIC RELATIVE TO ENVIRONMENTAL CONDITIONS. MULTISPECTRAL IMAGERY IS A RESEARCH TOOL FOR INVESTIGATIONS OF SEMI-AUTOMATIC MAPPING OF REFLECTANCE FROM SURFACES. LIMITED DATA ARE AVAILABLE ON THE SIGNIFICANCE OF REFLECTANCE FROM SOIL SURFACES. AREAS OF HIGH RELIEF DIFFERENCES REQUIRE THE ACCEPTANCE OF PERSPECTIVE DISTORTIONS ON MOSAICS OR PHOTOGRAMMETRIC COMPILATION OF THEMATIC MAPS. FOR MOST ENGINEERING SITE SELECTION AND DESIGN STUDIES, THE PERSPECTIVE DISTORTIONS OF AERIAL PHOTOGRAPHY ARE ACCEPT- ABLE. TOTAL VIEW OF THE TERRAIN AND THE SOIL ENVIRONMENT SHOWN ON ANNOTATED COLOR AERIAL PHOTOGRAPHS IS MORE IMPORTANT THAN GEOMETRIC ACCURACY. /AUTHOR/
