TECHNIQUES FOR UTILIZING SIDE-LOOKING AIRBORNE RADAR (SLAR) IMAGERY IN REGIONAL HIGHWAY PLANNING

SIDE-LOOKING AIRBORNE RADAR (SLAR) IS A SELF-ILLUMINATING, IMAGING SENSOR CAPABLE OF OPERATING OVER A WIDE WAVELENGTH RANGE IN A SIDE-SCANNING MODE. FEASIBILITY STUDIES HAVE DEMONSTRATED THE POTENTIAL VALUE OF SLAR IN TERRAIN ANALYSIS, GEOLOGIC AND PLANIMETRIC MAPPING, VEGETATION CLASSIFICATION, AND A MULTITUDE OF RELATED EARTH SCIENCE DISCIPLINES. THIS PAPER PRESENTS A PROCEDURE IN WHICH SLAR IMAGERY STRIPS OR MOSAICS CAN BE UTILIZED AS THE PRIMARY PRESENTATION OF TERRAIN DATA FOR THE REGIONAL PLANNING OF TRANSPORTATION SYSTEMS. THE SLAR IMAGE STRIP OF MOSAIC CAN SERVE AS A BASE MAP OF EXISTING MAJOR CULTURAL FEATURES AS WELL AS A PRESENTATION FROM WHICH REGIONAL CLASSIFICATIONS OF ENGINEERING SOIL TYPES, DRAINAGE, AND TOPOGRAPHY CAN BE MADE. TECHNIQUES FOR MEASURING AND INTERPRETING THESE FACTORS FROM SLAR IMAGERY ARE PRESENTED ALONG WITH AN EVALUATION OF THEIR RELIABILITY. INCLUDED ARE IMAGE TEXTURE AND RETURN ANALYSES AS WELL AS INTERPRETATION KEYS. ADVANTAGES AND DISADVANTAGES OF SLAR IMAGERY ARE COMPARED WITH THE CONVENTIONAL PHOTOGRAPHY AND TOPOGRAPHIC MAPS CURRENTLY USED FOR REGIONAL HIGHWAY PLANNING. /AUTHOR/
