NAVAIR — NGS TU1661 — Kapolei, US

This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental control framework for mapping and surveying activities throughout the United States. As a trig point, this station served as a primary control vertex for precise positioning and distance measurements in support of accurate cartography and engineering projects. Located near Kapolei on the island of Oahu, Hawaii, this benchmark occupies a strategic position within the Hawaiian Islands geodetic network. Trigonometric stations of this classification typically provided intervisible control points for extending surveys across regions lacking established infrastructure. The preservation and verification of such geodetic monuments remains valuable for surveying professionals undertaking projects requiring reference to the national datum. Documentation of existing control points enables practitioners to assess positional accuracy and maintain continuity with historical survey work. Regular confirmation of benchmark integrity supports the reliability of contemporary surveying operations across Hawaii.
