POT 124+29.46 LUALUALEI — NGS TU1722 — Kapolei, US

This triangulation station is part of the NGS network, which maintains the fundamental control infrastructure for surveying and mapping throughout the United States. Located near Kapolei on the island of Oahu, Hawaii, this trig point serves as a reference station for horizontal positional control. Triangulation stations historically anchored the geodetic framework by establishing precise horizontal coordinates across regions and between islands. The coordinates 21.38767°, -158.15207° provide reference control for cadastral surveys, engineering projects, and cartographic work in the Hawaiian Islands. Verification and documentation of such benchmarks remain essential for preserving geodetic continuity, ensuring consistency in surveying operations, and maintaining the accuracy of regional geographic information systems. Professional surveyors routinely reference established control points to validate local surveys and connect them to the national datum.
