6 7A — NGS DR2158 — Waipahu, US

This trigonometric station is part of the National Geodetic Survey's network, which establishes fundamental horizontal and vertical control for surveying and mapping across the United States. Trig stations serve as precision reference points for triangulation networks, enabling surveyors and engineers to conduct accurate position determinations and project layouts. Located in the vicinity of Waipahu on the island of Oahu, Hawaii, this point contributes to geodetic control in the Hawaiian archipelago. The station's coordinates in the North American Datum provide a stable reference for cadastral surveys, infrastructure development, and geographic information systems. Verification and documentation of such benchmarks remain essential for maintaining the integrity of the national geodetic framework and ensuring consistency in surveying practices across diverse geographic regions.
