GLO — NGS TU1587

This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational control framework for surveying and mapping throughout the United States. Located at coordinates 21.56092°N, 158.23852°W, this point lies within Hawaiian territory. Triangulation stations of this type serve as primary reference points for horizontal positioning and are typically monumented for long-term stability and recovery. The NGS network enables surveyors, cartographers, and engineers to reference their local work to a consistent national datum. While the elevation for this station has not been recorded in available documentation, verification and documentation of such control points remain critical for maintaining geodetic infrastructure accuracy and ensuring the integrity of spatial data across jurisdictions. Recovery and re-observation of existing benchmarks supports quality assurance in surveying operations.
