HO 10 — NGS TU0664 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which forms the foundation of the United States' geodetic reference system. Trig stations serve as precisely positioned control points for surveying, mapping, and engineering projects. Located near Kapolei on the Island of Oahu, Hawaii, at coordinates 21.33389°N, 158.02333°W, this benchmark contributes to the regional control network for the Hawaiian Islands. Triangulation stations of this type were historically established to create a framework of known positions from which surveyors could reference local measurements. Documentation and verification of such points remain valuable for maintaining survey accuracy, supporting infrastructure development, and ensuring consistency in spatial data. Surveyors and geodesists depend on these reference points to establish local coordinate systems and validate positioning equipment.
