California Spatial Reference Center Csrc

The California Spatial Reference Center (CSRC), established in 1997, is responsible for defining, maintaining, and publishing the California Spatial Reference System (CSRS) for our many stakeholders, including local and state organizations, academia, and the public and private sectors. We are committed to ensure the CSRS is aligned with the National Spatial Reference System (NSRS) in support of the National Oceanic and Atmospheric Administration (NOAA) and its National Geodetic Survey’s (NGS) mission and with the backing of the California Department of Transportation (Caltrans). The underlying CSRS framework is provided by the California Spatial Reference Network (CSRN) and consists of approximately 900 continuous Global Navigation Satellite System (GNSS) stations, 700 of which are providing real-time data through the California Real Time Network (CRTN). The CRTN serves as a clearinghouse of data contributed by our many partners at UNAVCO, University of California Berkeley, the U.S. Geological Survey (USGS), Caltrans, and San Diego and Orange Counties. Through the CSRS and CRTN, we monitor and quickly restore the precise spatial fabric in areas disrupted by the devastating effects of geophysical, natural, and anthropogenic processes often experienced by the people of California. https://linktr.ee/csrc_crtn
