This triangulation station is part of the National Geodetic Survey's fundamental control network, which establishes the geometric framework for surveying and mapping throughout the United States and its territories. Located near Kapolei on the island of Oahu, Hawaii, this trig point serves as a reference station for horizontal positioning in the Hawaiian Islands region. Triangulation stations of this type are monumented points established to support accurate geodetic measurements and to enable surveyors, engineers, and cartographers to reference their work to a common datum. The coordinates provided in the NGS registry allow users to recover this point's position for verification, monument inspection, and continuation of local survey networks. Regular documentation and validation of such control points remain essential for maintaining the integrity of Hawaii's geodetic infrastructure and supporting infrastructure development, land surveying, and scientific applications requiring precise positional reference.
