NS 1 — NGS DR2308 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational geodetic control for the United States. Triangulation stations serve as fixed reference points for surveying, mapping, and engineering projects requiring precise horizontal positioning. Located in the Kapolei area of Oahu, Hawaii, at coordinates 21.33906°N, 158.05308°W, this trig point contributes to Hawaii's surveying infrastructure. Such stations are typically monumented markers—often brass disks or stone cairns—that survive decades or longer, providing surveyors and engineers with reliable control points for cadastral surveys, construction projects, and spatial data development. Documentation and periodic verification of these monuments ensure their continued utility. The NGS maintains records of station coordinates, descriptions, and recovery histories to support professional surveying activities throughout Hawaii and the Pacific region. This point's inclusion in the geodetic network reflects its role in supporting accurate spatial referencing across the islands.
