PUPUKEA RESET — NGS TU1504 — Honolulu County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal control framework for the United States. Trig stations of this classification serve as precise reference points for surveying, mapping, and engineering projects across multiple jurisdictions and scales. Located in Honolulu County, Hawaii, this point contributes to geodetic control in the Hawaiian Islands, a strategically important region for Pacific surveying operations. The coordinates provided establish its position within the broader NGS horizontal datum. Documentation and verification of such control points remains essential for maintaining the integrity of the national spatial reference system. Surveyors and engineers rely on these established benchmarks to ensure accuracy in property surveys, construction projects, and cartographic applications. Periodic inspection and recovery of these monuments supports long-term geodetic infrastructure stability and data quality across the state.
