Evaluation of interferometric synthetic aperture radar (InSAR) techniques for measuring land subsidence and calculated subsidence rates for the Escalante Valley, Utah, 1998 to 2006 (OFR-589) Petroglyphs & Pictographs 000 scale topographic mapBy: R. R. Forster Previous studies have shown the Escalante Valley, Utah, is subsiding due to groundwater withdrawal. The magnitude and spatial pattern of this cm yr. scale subsidence is mapped with satellite data from a synthetic aperture radar (SAR) using interferometric SAR (InSAR) processing techniques. A relatively new processing approach that measures individual pixel displacements for selected persistent scatterers (PSInSAR) was tested in the
