Western Remote Sensing and Visualization Center
The California District Center for Interferometric Synthetic Aperture Radar
(InSAR) Western Remote Sensing and Visualization Center supports USGS investigations
of aquifer-system compaction and resulting land-surface elevation changes (subsidence
and uplift) through the processing and interpretation of InSAR data. InSAR is
a powerful tool that uses radar signals to measure deformation of the Earth's
crust at unprecedented spatial detail and high degree of measurement resolution,
and is often less expensive than obtaining sparse point measurements from labor-intensive
spirit-leveling and Global Positioning System (GPS) surveys. Western Remote Sensing and Visualization Center provides
InSAR support and products for USGS water-resources investigations, and has
been or is presently active in arid and (or) urban areas in California, Nevada,
New Mexico, Texas, and Wyoming. For additional information, contact Michelle
Sneed.
