FENCE — NGS TU1569

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping activities throughout the United States. Trigonometric stations serve as precisely positioned reference points used to support larger-scale geodetic surveys and local surveying projects. Located at coordinates 21.56067° N, 158.23849° W in Hawaii, this point contributes to the geodetic infrastructure of the Pacific region. As a trig point, it provides horizontal control for surveys conducted by government agencies, private surveyors, and mapping professionals. Verification and documentation of such benchmarks remain essential for maintaining the accuracy and continuity of the national spatial reference system. The preservation and recovery of these control points support critical infrastructure development, land management, and surveying operations across their respective regions.
