Image resolution (X,Y) is 0.0011335842, 0.00089982004 degrees, or approximately 100 meters. Vertical ground surface displacement estimates are derived from Interferometric Synthetic Aperture Radar (InSAR) data that are collected by the European Space Agency (ESA) Sentinel-1A satellite and processed by TRE ALTAMIRA, under contract with to the California Department of Water Resources (DWR) as part of DWR’s SGMA technical assistance to provide important SGMA-relevant data to GSAs for GSP development and implementation. Sentinel-1A InSAR data coverage for the entire study area began in June 13, 2015. The Department of Water Resources makes no warranties, representations or guarantees, either expressed or implied, as to the accuracy, completeness, correctness, or timeliness of the information in this dataset, nor accepts or assumes any liability arising from use of these data. Neither the Department nor any of the sources of this information shall be responsible for any errors or omissions, or for the use or results obtained from the use of this information. A Groundwater Sustainability Agency is not required to use these data, and their use does not guarantee the adequacy of a Groundwater Sustainability Plan that relies on such data.

Date of acquisition: Between January of 2015 and April of 2022. Date of production: 2022. Date of delivery of product: Delivered from TRE ALTAMIRA to DWR in June of 2022. Processing steps: See Technical Report: InSAR land surveying and mapping services to DWR supporting SGMA - October 2021 Update, TRE ALTAMIRA, 2021. Pixel value definitions: Vertical ground surface displacement in feet for time period specified above.
