JRF C — NGS DR8484 — Kapolei, US

This trigonometric station is part of the National Geodetic Survey's network of control points, which establishes the fundamental reference framework for surveying and mapping throughout the United States. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.31493° N, 158.06279° W with an ellipsoidal elevation of 25.3 meters, this trig point serves as a positional reference for local and regional surveys. Trigonometric stations of this type are essential for accurately determining horizontal and vertical control across land areas. The NGS maintains these benchmarks to support cadastral surveys, engineering projects, and cartographic work. Verification and documentation of such control points ensure the integrity of Hawaii's surveying infrastructure and facilitate interoperability with broader national geodetic networks. Surveyors and geodesists depend on the continued maintenance and accessibility of these reference stations for precise work.
