CSRC Projects
    The California Spatial Reference System is a high-accuracy vertical and horizontal geodetic network serving as California's official reference system for all surveying activities. It is composed of a network of California CORS sites, campaign surveys such as the projects listed below, and the geodetic models necessary to utilize the network of sites.
