SLAR IMAGERY AND SITE SELECTION

A SYSTEMATIC SLAR IMAGE INTERPRETATION PROCEDURE HAS BEEN DESIGNED FOR REGIONAL ENGINEERING SITE SELECTION STUDIES. ENGINEERING SOIL TYPES (PATENT MATERIALS) ARE INFERRED FROM DRAINAGE, TOPOGRAPHIC, AND LAND USE PATTERNS IN A MANNER SIMILAR TO THE CONVENTIONAL AIRPHOTO INTERPRETATION PROCEDURE. UNIQUE TO SLAR IMAGERY, HOWEVER, THESE PATTERNS MUST BE EVALUATED WITH RESPECT TO PATTERN ELEMENTS CHARACTERIZING THE INTERACTIONS BETWEEN RADAR ENERGY AND THE LAND SURFACE. THE PATTERNS ARE CREATED FROM DISCRETE TONAL ELEMENTS, AVERAGE AREAL TONES, AND SLAR IMAGE TEXTURES; ALL OF WHICH PROVIDE INFORMATION SUPPLEMENTAL TO THAT CONTAINED IN CONVENTIONAL PHOTOGRAPHY. WHERE THE INTERPRETATION OF ENGINEERING SOIL TYPE IS COMPLEMENTED WITH AN ANALYSIS OF REGIONAL TERRAIN ROUGHNESS, A POWERFUL TOOL FOR PRELIMINARY SITE SELECTION IS ACHIEVED. REGIONAL RELATIONSHIPS BETWEEN SOIL TYPE, TOPOGRAPHY, AND DRAINAGE WHICH ARE OFTEN OBSCURED ON CONVENTIONAL PHOTOGRAPHY ARE EMPHASIZED ON SMALL SCALE SLAR IMAGES. THE DIAGNOSTIC PATTERN ELEMENTS AND RESULTANT PATTERNS CHARACTERISTIC FOR A VARIETY OF ENGINEERING SOIL TYPES AND TERRAIN CONDITIONS COMPRISE AN EXAMPLE. /AUTHOR/
