SOH 15 — NGS DR2078 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network of control points that form the foundation of the United States' official geodetic reference system. Situated near Kapolei on the island of Oahu, Hawaii, at an ellipsoidal elevation of 19.0 meters, this trig point serves as a horizontal control reference for surveying and mapping activities throughout the Hawaiian Islands region. Triangulation stations of this type establish precise spatial coordinates that enable surveyors, engineers, and cartographers to conduct accurate fieldwork and establish local coordinate systems. The documented position and elevation of this benchmark provide essential verification data for professional surveyors conducting cadastral surveys, infrastructure projects, and geographic information system development. Regular confirmation of such geodetic reference points ensures the continued integrity and reliability of Hawaii's surveying infrastructure and supports interoperability with national positioning networks.
