8 9 — NGS TU0617 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal and vertical control framework for the United States. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.36943° N, 158.13744° W, this trig point serves as a reference station for surveying and mapping activities throughout the Hawaiian Islands region. Triangulation stations of this type historically formed the backbone of precise geodetic control, enabling surveyors to establish accurate positions for subsequent survey work. The NGS network remains valuable for verifying the integrity of modern positioning systems and for conducting surveys requiring high-order accuracy. Documentation and periodic verification of such benchmarks ensure their continued utility for surveyors, engineers, and cartographers dependent on reliable reference stations for positioning and spatial data collection.
