PUU KAILIO 2500 1969 — NGS TU1686 — Kapolei, US

This trigonometric station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Trigonometric points serve as precise control stations used to support surveying, mapping, and engineering projects across regions. Located near Kapolei on the island of Hawaii, this benchmark provides vertical and horizontal control for local surveying activities in the Hawaiian archipelago. The coordinates are referenced to the national datum system. Verification and documentation of such control points remain essential for maintaining survey accuracy and integrity across successive projects. Surveyors and geodetic professionals rely on these established stations to ensure consistency in spatial measurements and to reduce systematic errors in detailed surveys. Proper cataloging and periodic inspection of benchmark stations help preserve the long-term utility of the national geodetic network.
