PUU O HULU NORTH — NGS TU1691 — Kapolei, US

This NGS trigonometric station is located in the Kapolei area of Hawaii and serves as a control point within the National Geodetic Survey's network. Trig stations function as fundamental reference markers for cadastral surveys, mapping projects, and infrastructure development across the United States and its territories. The coordinates 21.40390°, -158.15605° establish a precise horizontal position for this benchmark within Hawaii's geodetic framework. As part of the NGS network, this point contributes to the continental and island-based control infrastructure essential for accurate surveying and geographic information systems. Verification and documentation of such benchmarks remain critical for maintaining data integrity in surveying operations and ensuring consistency in coordinate systems across decades of land records and development projects. Field surveys and GPS observations may be used to reestablish or confirm the position of existing control points.
