8 4 — NGS TU0605

This triangulation station is part of the NGS network, which establishes and maintains the fundamental geodetic framework for the United States. Triangulation stations serve as precisely positioned control points essential for surveying, mapping, and engineering projects at local and regional scales. Located at coordinates 21.44083°N, 158.19072°W in US territory, this benchmark provides horizontal control data for surveyors and cartographers conducting work in its vicinity. As a trig point, it was historically established through intervisibility methods to create networks of known positions across the landscape. Documentation and verification of such control stations remain valuable to the surveying profession. Periodic recovery and assessment of these marks ensure their reliability for modern applications including infrastructure development, property boundary establishment, and geospatial analysis. Accurate records of benchmark location and condition support the continuity of geodetic reference systems.
