KUNIA RADIO STA KAHU MAST — NGS TU1631 — Waipahu, US

This trigonometric station is part of the National Geodetic Survey's foundational control network, which establishes the geometric framework for surveying and mapping throughout the United States. Located near Waipahu on the island of Oahu, Hawaii, this benchmark serves as a reference point for horizontal positioning and triangulation work across the Hawaiian Islands region. Trigonometric stations of this type were traditionally established to provide accurate spatial control for large-scale surveying projects, including topographic mapping and engineering applications. The point's coordinates, referenced in the NGS database, enable surveyors and cartographers to tie local measurements to the national geodetic datum. Verification and proper documentation of such control points remain essential to surveying practice. Despite the elevation not being recorded for this particular station, its horizontal coordinates preserve valuable reference data for professional surveyors operating in Hawaii and support the integrity of the broader control network.
