E 14 — NGS TU0621 — Kapolei, US

This geodetic reference point is a triangulation (trig) station within the NGS network, which forms the foundation of the United States' positional control infrastructure. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.34428° N, 158.11575° W, this monument serves as a precise horizontal control point for surveying and mapping activities across the Hawaiian Islands region. Trig stations of this type historically provided essential reference marks for establishing accurate survey networks through triangulation methods. Such points remain valuable for verifying and maintaining spatial data accuracy in professional surveying, engineering, and geographic information systems work. Documentation and periodic verification of these benchmarks ensures the integrity of the geodetic framework upon which larger surveying projects depend. The NGS benchmark registry preserves critical information for surveyors requiring high-precision positional references.
