PARK ROW MON — NGS DL6338 — Kapolei, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the official geodetic control framework for the United States. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.34584° N, 158.03834° W, this trig point serves as a fundamental reference for surveying and mapping operations throughout the Hawaiian Islands. Triangulation stations of this type historically provided precise three-dimensional positional control by establishing intervisible points across terrain. With an ellipsoidal elevation of 33.7 meters, this benchmark contributes to both horizontal and vertical control networks essential for accurate cadastral surveys, engineering projects, and geospatial applications. Documentation and periodic verification of such control points remain critical to maintaining the integrity of surveying networks and ensuring consistency in spatial data collection across jurisdictions.
