STATE SURVEY 8 5 — NGS TU1694

This triangulation (trig) station is part of the National Geodetic Survey's network, which establishes the foundational control points for precise positioning and mapping across the United States. Trig stations serve as primary control monuments used in surveying, engineering, and mapping projects to provide accurate horizontal coordinate references. Located at 21.44933°N, 158.18485°W in the United States, this point contributes to geodetic coverage in its region. As a trig-class monument, it was historically established to support large-scale surveys and remains valuable for verification and validation of contemporary survey work. Proper documentation and maintenance of such reference points is essential for ensuring consistency in surveying practice and mapping accuracy. Verification of existing benchmarks and recovery of their coordinates assists surveyors in establishing local control networks and conducting precise geospatial work.
