MOKULEIA — NGS TU1536

This trigonometric station is part of the National Geodetic Survey's passive control network, which establishes the fundamental horizontal datum for the United States. Trigonometric stations serve as primary survey monuments, providing precise geographic reference points for subsequent mapping, engineering projects, and land boundary determinations. Located in Hawaii at coordinates 21.57872° N, 158.16811° W, this benchmark contributes to regional geodetic infrastructure across the Pacific. The elevation has not been recorded in available documentation. Like all NGS control points, this station's value derives from its documented position and accessibility for verification by licensed surveyors. Regular confirmation of such monuments' integrity and continued monumentation ensures the reliability of the national spatial reference system. Professionals undertaking surveys in this region should consult current NGS data to verify the point's condition and positional accuracy.
