KPH 1965 — NGS TU1599

This is a triangulation station within the NGS network, the primary geodetic framework for the United States. Triangulation stations serve as high-precision horizontal control points, established to support surveying, mapping, and engineering projects across the nation. Located at coordinates 21.57290° North, 158.27273° West, this point falls within the Hawaiian archipelago region. As a trig station, this benchmark was positioned to enable accurate distance and direction measurements through intervisible networks of control points. Such stations are essential components of the National Spatial Reference System, providing foundational accuracy for cadastral surveys, infrastructure development, and geospatial data collection. Documentation and verification of existing benchmarks remain critical for maintaining the integrity of geodetic networks. Confirming the physical condition, accessibility, and positional accuracy of these reference points ensures their continued utility for surveying professionals and supports the reliability of downstream mapping and positioning activities.
