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 The important coal bed penetrated

The important coal bed penetrated in the Johns Peak area is thought to be the upper Ivie and is 4 to 6 feet thick

it serves as a practical guide to understanding elevation changes across the state

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 The important coal bed penetratedBy: 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
