This triangulation station is part of the National Geodetic Survey's network of control points that form the foundation of the United States' geodetic infrastructure. Located near Kapolei on the island of Oahu, Hawaii, this trig point serves as a reference for horizontal position control in surveys and mapping activities across the Hawaiian region. Triangulation stations of this type were established to provide accurate geodetic control through the intersection of sight lines between known points. The coordinates 21.34011° N, 158.07572° W define its horizontal position within the NGS network. Verification and documentation of such reference points remain essential for surveyors, engineers, and cartographers conducting work in Hawaii. Maintenance of these control networks ensures the integrity of local and regional surveying projects and contributes to the broader national spatial reference framework.
