This triangulation station is part of the NGS network, which establishes and maintains the fundamental geodetic framework for the United States. Trig stations serve as control points for surveying, mapping, and engineering projects requiring precise horizontal positioning. Located in the Alameda, California area at coordinates 37.77494°N, 122.24319°W, this benchmark contributes to regional spatial reference systems. As a trig point, it historically supported survey work through intervisible sight lines with other stations, enabling accurate distance and angle measurements across the landscape. Documentation and periodic verification of such control points remain essential for maintaining the integrity of the national geodetic datum and supporting contemporary applications in surveying, construction, and geographic information systems. The preservation of these reference marks ensures consistency and reliability in spatial data across multiple generations of surveying activity.
