STATE SURVEY 9 2 1969 — NGS TU1671 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which provides the foundational geodetic control for the United States. Triangulation stations serve as precisely positioned reference points established through classical surveying methods to support mapping, engineering projects, and spatial data infrastructure across the country. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.34323°N, 158.11271°W, this benchmark contributes to the geodetic framework for the Hawaiian Islands. Such control points are essential for local and regional surveying activities, enabling surveyors, engineers, and researchers to establish accurate measurements and coordinate systems. Documentation and verification of these geodetic monuments remain important for maintaining the integrity of surveying networks. The preservation and accessibility of benchmark data supports continued reliance on established reference frames for construction, land administration, and scientific applications throughout Hawaii and beyond.
