This is a triangulation station within the National Geodetic Survey network, which forms the backbone of the United States' horizontal geodetic control infrastructure. Situated near Alameda, California, at coordinates 37.73631° N, 122.25655° W, this trig point serves as a reference for surveying and mapping activities across the region. The ellipsoidal elevation of -28.3 meters reflects the point's position in relation to the WGS 84 reference ellipsoid. Trig stations of this type were historically established to create precise networks for large-scale surveying projects. Modern surveyors and mapping professionals continue to rely on NGS-maintained control points for validating GNSS observations, conducting cadastral surveys, and ensuring consistency in spatial data. Verification and documentation of such reference points remain essential for maintaining the integrity of the nation's geodetic framework and supporting civil infrastructure projects.
