Center for InSAR Monitoring of Deforming Aquifer Systems (CIMDAS)
The California District Center for Interferometric Synthetic Aperture Radar (InSAR) Monitoring of Deforming Aquifer Systems (CIMDAS) 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. CIMDAS 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.
