RAD — NGS TU1603

This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational horizontal and vertical control framework for the United States. Trigonometric stations serve as primary reference points for precise surveying, mapping, and engineering projects across their respective regions. Located at coordinates 21.56913°N, 158.26262°W, this benchmark lies within Hawaiian territory. Triangulation stations of this type historically provided essential ground control for larger-scale geodetic surveys and continue to support modern positioning efforts. Verification and documentation of existing benchmarks remain valuable for surveyors and geospatial professionals who require reliable reference points for local projects and coordinate system validation. Recording the current condition and accessibility of such stations helps maintain the integrity of the nation's geodetic infrastructure and supports continuity in surveying practices.
