This trigonometric station is part of the National Geodetic Survey's horizontal control network, which establishes the foundational reference framework for surveying and mapping across the United States. Trigonometric stations serve as primary control points for determining precise horizontal positions and supporting subsequent survey work at local and regional scales. Located near Alameda, California, at coordinates 37.77180°, -122.24293°, this point contributes to the geodetic infrastructure of the San Francisco Bay Area. Trig stations of this classification are typically monumented to ensure permanence and recoverable access for verification by future surveyors. Documentation and periodic recovery of such benchmarks remain essential for maintaining survey accuracy, supporting infrastructure projects, and ensuring consistency within the National Spatial Reference System. Verification of existing control points helps identify any movement or disturbance affecting their reliability as reference positions.
