Optimizing Image Scale and Resolution to Obtain Lineament Related Structures using ALOS PALSAR Dual Orbit Data

Abstract Geological structures identification using conventional optical remote sensing encountered some problems due to atmospheric and surface conditions. Therefore, we exploited the Synthetic Aperture Radar (SAR) in Ascending Descending orbits characterize lineaments related geological structures. We have analyzed two images from Phased Array type L-band (PALSAR) onboard Advanced Land Observing Satellite (ALOS). The adjustment of their resolution multilooking process was applied obtain best understanding between detected lineament reference fault. cross-polarized data ALOS PALSAR level SLC were multilooked with variation 15 120 m. Obtaining optimum lineament-related faults, which Yamaguchi criterion extract visually images. Kamojang-Guntur Geothermal Fields West Java selected as a study area because there is challenge confirm structure high alteration weathering According proposed criterion, obtained those 75 90 analysis can represent conditions, correlation existing published map. field verifications been confirmed that indication has proved existence slickenside morphological conditions such drainage rivers, ridges, valleys. Based on lineaments, stress regimes, verifications, it concluded image m describe presence regional interpreted
