OPIHILALA RESET — NGS TU2644 — Hawaiʻi County, US

This trigonometric station is part of the National Geodetic Survey's network, which establishes the fundamental geodetic infrastructure for the United States. Trigonometric stations serve as control points for horizontal positioning and triangulation work, essential for accurate surveying, mapping, and construction projects. Located in Hawaiʻi County, Hawaii, at coordinates 20.04162° N, 155.37389° W, this benchmark contributes to geodetic control in the Hawaiian Islands. Such stations are typically monumented points of known position that surveyors reference when conducting detailed surveys at regional and local scales. The documentation and verification of existing geodetic marks remain valuable for the surveying profession. Confirming the stability, accessibility, and positional accuracy of established benchmarks ensures continuity in surveying operations and supports the integrity of spatial data infrastructure across the islands.
