8 10 — NGS TU0575 — Honolulu County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the foundational control points for surveying and mapping throughout the United States. Located in Honolulu County, Hawaii, this trig point serves as a reference marker for horizontal positioning in the region. Triangulation stations of this type historically provided essential control for large-scale surveys and continue to support modern geodetic work, including verification of contemporary satellite-based positioning systems. The documented coordinates enable surveyors and engineers to establish local datums and verify survey networks. As part of the NGS registry, this benchmark contributes to the nation's geodetic infrastructure. Verification and maintenance of such control points remain valuable for ensuring consistency in surveying operations and for documenting the evolution of positional reference systems across the Hawaiian Islands.
