DRILL HOLE CROSS ON ROCK — NGS TU1713 — Kapolei, US

This trigonometric station is part of the National Geodetic Survey's network, which establishes and maintains the geodetic control framework across the United States. As a trig point, this benchmark serves as a fundamental control station for surveying, mapping, and engineering projects throughout Hawaii. Located near Kapolei on the island of Oahu, this station contributes to regional positional accuracy and provides essential reference coordinates for subsequent surveys and infrastructure development. Trig stations of this classification are typically monumented points of high precision, used to support cadastral surveys, topographic mapping, and construction projects. The documented coordinate position at 21.44547°, -158.16990° provides surveyors and engineers with a reliable reference for local work. Verification and proper documentation of such geodetic control points remain valuable for maintaining survey accuracy, particularly in areas undergoing development. Current condition and accessibility information should be confirmed prior to field use.
