Abstract :
Understanding the effects of regional subsidence in New Orleans, Louisiana requires knowledge of a number of factors (coast-parallel normal growth faults, deltaic deposit system, fluid withdrawal, etc). High accuracy and spatially dense subsidence data that can be obtained by TerraSAR-X (TSX) InSAR analysis can help to separate these various subsidence processes. In this study we report first X-band InSAR result using TerraSAR-X to detect urban subsidence with high spatial resolution. Our results can be tested against other InSAR results that may be derived from ERS, ENVISAT, and RADARSAT-1 and RADARSAT-2. These comparisons will provide useful tests for the general applicability and accuracy of the new X-band space-borne SAR interferometry.
