INVESTIGATION OF THE INTEGRATION OF AVIRIS AND IFSAR FOR URBAN ANALYSIS

Most attempts at urban analysis using remotely sensed imagery lack the capabilities necessary to define the detailed geometry and differenti ate the textures of the complex urban landscape. This paper presents a proof-of-concept study of the potential for integrative analysis of I nterferometric Synthetic Aperture Radar (IFSAR) and Airborne Visible/i nfrared imaging Spectrometer (AVIRIS) hyperspectral imagery for a stud y area in Los Angeles, California. Recent advances in the use of inter ferometric radar allow the definition of high resolution, three-dimens ional (3D) geometry of surface features, topography, and impervious su rfaces in urban areas. The radar analysis is enhanced using hyperspect ral imagery to mask surfaces adjacent to structures in order to assist in the determination of baseline topography and segmentation of build ing footprints for improved geometric measurement of the complex urban area.
