J 15 — NGS TU0546

This trigonometric station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental control framework for surveying and mapping activities throughout the United States. Trig stations of this classification serve as precisely positioned reference points used to support terrestrial surveys, GPS networks, and cartographic projects. Located at coordinates 21.57797° N, 158.17039° W in Hawaii, this benchmark contributes to the geodetic infrastructure of the Pacific region. The elevation data for this station has not been recorded in available documentation. Verification and documentation of such control points remain essential for maintaining survey accuracy and supporting subsequent engineering, construction, and scientific applications that depend on reliable positional references. Surveyors and geodetic professionals rely on these established monuments to ensure consistency and quality in their work.
