SOH 10A — NGS DR2072

This triangulation station is part of the National Geodetic Survey's foundational control network, which establishes the geometric framework for mapping and surveying throughout the United States. Trigonometric stations serve as primary reference points for horizontal positioning, enabling surveyors and cartographers to conduct precise measurements and establish local control networks. Located at coordinates 21.41031°N, 158.17700°W in US territory, this benchmark contributes to geodetic coverage in the Pacific region. The point's classification as a trig station indicates its historical significance within NGS's classical triangulation methodology, which formed the backbone of American surveying practices. Verification and documentation of such reference points remain valuable for surveying professionals, as they provide connection to the National Spatial Reference System and facilitate accurate geographic information collection. Maintaining records of benchmark locations and their characteristics supports continuity in surveying operations and geodetic research.
