This trigonometric station is part of the National Geodetic Survey's comprehensive network of control points establishing the geodetic framework for the United States. Located in the Kapolei area of Hawaii, this trig point serves as a reference station for surveying and mapping activities across the Hawaiian islands. Trig stations of this type were historically established to provide accurate horizontal positioning for cadastral surveys, engineering projects, and cartographic work. The point's coordinates in the NGS database enable surveyors to reference local measurements to the national datum system, ensuring consistency and accuracy in land surveys, construction projects, and geographic information systems. Verification and maintenance of such benchmarks remain important for sustaining the integrity of Hawaii's surveying infrastructure and supporting precise positioning activities requiring connection to established geodetic control.
