This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational geodetic infrastructure for the United States. Trigonometric stations serve as precisely positioned control points essential for large-scale surveying, mapping, and engineering projects across the country. Located at coordinates 21.57439° N, 158.27999° W in the Hawaiian Islands, this benchmark contributes to regional positional accuracy and terrestrial reference frameworks. The point's integration into the NGS network enables surveyors and cartographers to conduct accurate measurements and maintain spatial data consistency. Documentation and periodic verification of such geodetic control points remain vital to surveying practice. These stations provide established references that reduce measurement uncertainty and ensure compatibility between independent surveys. Maintenance of complete registry records, including coordinate data and physical descriptions, supports the long-term utility of the geodetic network for professional surveying applications.
