NS 3 — NGS DR2310 — Kapolei, US

This trigonometric station is part of the National Geodetic Survey network, which establishes and maintains the official geodetic framework for the United States. Trig stations serve as primary control points for surveying and mapping activities, providing accurate horizontal position references for subsequent surveys and engineering projects. Located near Kapolei on the island of Hawaii, this benchmark contributes to Hawaii's geodetic infrastructure and supports both public works and private surveying endeavors throughout the region. The coordinates 21.35514°, -158.05006° define its precise horizontal position within the national coordinate system. Documentation and periodic verification of such control points remain essential to surveying practice, ensuring that subsequent surveys maintain consistency with established geodetic standards. Surveyors and engineers rely on these reference stations for accurate positioning of property boundaries, infrastructure development, and cadastral records.
