D 15 — NGS TU0594 — Honolulu County, US

This triangulation station is part of the National Geodetic Survey's network of control points that establish the geometric framework for surveying and mapping throughout the United States. Located in Honolulu County, Hawaii, this trig point serves as a reference for determining precise horizontal positions of other survey points and geographic features. Triangulation stations of this type were established to create accurate geodetic control networks essential for cadastral surveys, engineering projects, and cartographic work. The coordinates provided establish its location within the broader Hawaiian geodetic network. Surveyors and GIS professionals rely on documented benchmarks like this to verify survey work, calibrate equipment, and maintain positional accuracy across projects. Continued verification and documentation of such control points remains valuable for preserving the integrity of Hawaii's geodetic infrastructure and supporting future surveying operations requiring established reference positions.
