This triangulation (trig) station is part of the National Geodetic Survey's foundational control network, which establishes the geometric framework for surveying and mapping across the United States and its territories. Trig stations serve as primary reference points for horizontal positioning, traditionally established through intervisible networks of elevated markers used in classical triangulation surveys. Located in Hawaiʻi County, Hawaii, this benchmark occupies a strategic position within the Hawaiian archipelago's geodetic infrastructure. The coordinates 20.26291°N, 155.86195°W place it in the Big Island region, where such control points support local surveying, engineering projects, and spatial data applications. Verification and documentation of NGS benchmarks remain essential for surveyors and geospatial professionals. These points provide reproducible positional references for property surveys, construction projects, and scientific investigations. Maintaining accurate records of such stations ensures the integrity of the national spatial reference system.
