X 13 — NGS TU0609

This triangulation station is part of the NGS network, which establishes the primary geodetic control framework for the United States. Trig stations like this point serve as fundamental reference marks for surveying, mapping, and infrastructure projects requiring accurate horizontal positioning. Located at coordinates 21.42889°N, 158.18056°W in US territory, this benchmark contributes to the national spatial reference system. The elevation has not been recorded in available documentation. These control points enable surveyors and engineers to tie local measurements to the national datum, ensuring consistency across projects. Verification and proper documentation of such stations preserves their utility for future surveying work and maintains the integrity of the geodetic network. Professional surveyors may reference this point for establishing project baselines or validating positioning equipment.
