MANINI — NGS TU1592

This triangulation station is part of the NGS network, which maintains the primary geodetic framework for the United States. Trig stations like this one serve as fundamental control points for surveying, mapping, and engineering projects requiring precise horizontal positioning. Located at coordinates 21.57296°N, 158.25642°W in U.S. territory, this point contributes to the national spatial reference system. Trig stations historically provided intervisible points across landscapes for classical triangulation surveys, establishing accurate position networks before modern satellite techniques became prevalent. Documentation and verification of such benchmarks remain valuable for professionals conducting surveys, establishing local control networks, and validating historical survey work. Even points with incomplete elevation records provide essential horizontal control data. Maintenance of the NGS registry ensures continuity of geodetic infrastructure and supports accurate spatial reference for land and resource management across the country.
