M 15 — NGS TU0565

This trigonometric station is part of the National Geodetic Survey's network of control points that establish the geometric framework for surveying and mapping throughout the United States. Trigonometric stations serve as monumented horizontal control points, providing precise geographic positions for subsequent surveys and engineering projects. Located at 21.57560° N, 158.27274° W in the United States, this point contributes to the nation's geodetic datum. Verification and documentation of such benchmarks remain important for surveyors and engineers who rely on established control networks for accurate positioning work. The coordinates and classification data recorded in the NGS registry enable professionals to incorporate this reference point into their surveying operations. Regular inspection and maintenance of geodetic monuments help preserve the integrity of the control network for future surveying applications.
