SOH 89 — NGS DR2162 — Honolulu County, US

This trigonometric station is part of the National Geodetic Survey's network of control points establishing the geometric framework for surveying and mapping across the United States. Located in Honolulu County, Hawaii, this trig point serves as a reference station for horizontal positioning and triangulation work in the Hawaiian Islands region. As a fundamental control monument, this benchmark provides surveyors and engineers with an established geodetic position for local survey projects, cadastral work, and mapping initiatives. The NGS network remains essential to maintaining consistent spatial accuracy across public and private surveying activities nationwide. Verification and documentation of such reference points are critical for preserving geodetic infrastructure integrity. Regular confirmation of monument condition and coordinate values ensures continued utility for professional surveying practice and scientific applications requiring precise positional control.
