5 11 — NGS TU0513 — Honolulu County, US

This triangulation station is part of the NGS network, which maintains the foundational geodetic control for the United States. As a trig point, this station served historical surveying operations requiring precise horizontal positioning through intervisible sight lines and angular measurements. Located in Honolulu County, Hawaii, the benchmark is situated within an island context requiring robust control networks to support subsequent mapping and surveying activities across the archipelago. The coordinates provided establish a reference for local and regional surveys. Verification and documentation of such control points remain essential for surveyors conducting boundary work, engineering projects, and spatial analysis. While elevation data is not recorded in this registry entry, the horizontal positioning information contributes valuable continuity to Hawaii's geodetic infrastructure and supports modern positioning systems referencing established datums.
