SOH 38 — NGS DR2100 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal control framework for the United States. Located near Kapolei on the island of Oahu, Hawaii, this trig point serves as a reference for surveying, mapping, and engineering projects across the region. Triangulation stations of this type historically provided precise positional data through intervisible sight lines, supporting the development of accurate topographic maps and cadastral surveys. The coordinates 21.33428°, -158.05653° define its horizontal position within the geodetic datum. Verification and documentation of such benchmarks remain valuable for surveyors conducting boundary work, infrastructure projects, and validating modern positioning technologies. Maintaining records of these control points ensures continuity of spatial reference frameworks and supports quality assurance in surveying practice.
