SOH 86 — NGS DR2157 — Waipahu, US

This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental control points underlying surveying and mapping activities across the United States. Located near Waipahu on the island of Oahu, Hawaii, this trig point serves as a reference station for horizontal control at coordinates 21.53319°N, 158.04114°W. Triangulation stations of this type provide precise geodetic positions essential for large-scale surveying projects, infrastructure development, and cartographic accuracy. The NGS network integrates these control points into a coherent reference framework supporting civil engineering, land surveying, and scientific applications. Verification and documentation of such benchmarks remain valuable for professionals relying on stable, well-defined positional references. While elevation data is not currently recorded for this station, its horizontal coordinates provide reliable geometric control for regional surveying work.
