MAILI RESET — NGS TU1520 — Waipahu, US

This triangulation station is part of the National Geodetic Survey's network of reference points that form the foundation of the United States' horizontal and vertical control system. Situated near Waipahu on the island of Oahu, Hawaii, this trig point serves as a known position for surveying and mapping activities across the Hawaiian Islands region. Triangulation stations of this type were historically established to provide accurate geodetic control for large-scale surveys and remain valuable for validating modern positioning measurements. The coordinates 21.52170°N, 158.09329°W document its location within the geodetic framework. Verification and maintenance of such benchmark records ensures the continued reliability of the survey control network for engineering projects, land surveys, and scientific applications dependent on precise geographic reference data.
