This triangulation station is part of the National Geodetic Survey's trigonometric network, which establishes the geometric framework for precise surveying and mapping across the United States. Located in Honolulu County, Hawaii, at coordinates 21.65135° N, 158.06160° W, this point serves as a control station for horizontal position determination. Trigonometric stations of this type are monumented points whose positions have been determined through geodetic measurement techniques. They function as reference marks for local surveys, engineering projects, and geographic information systems. Verification and documentation of such benchmarks remain essential for maintaining the integrity of the national spatial reference system. Professional surveyors rely on these established control points to ensure consistency and accuracy in their work. Periodic recovery and reobservation of these monuments helps detect any displacement or degradation that may affect their utility for future surveying operations.
