ANTENNA — NGS TU0993 — Waipahu, US

This triangulation station is part of the National Geodetic Survey's network of control points that establishes the geometric framework for surveying and mapping across the United States. Located near Waipahu on the island of Oahu, Hawaii, at coordinates 21.52098° N, 157.99707° W, this trig point serves as a reference for local and regional surveys requiring precise horizontal positioning. Triangulation stations of this type were historically observed using theodolites and form the backbone of Hawaii's geodetic infrastructure. Such monuments remain valuable for verifying modern GPS and survey-grade measurements, establishing consistency across mapping projects, and maintaining positional continuity for infrastructure development. Documentation and preservation of these reference points ensures their continued utility for professional surveyors and engineers conducting work in the Hawaiian Islands.
