6 9G — NGS DR2148 — Honolulu County, US

This trigonometric station is part of the National Geodetic Survey's network of control points establishing the geodetic framework for the United States. Trigonometric stations serve as fundamental reference points for surveying, mapping, and engineering projects, providing precise horizontal control through triangulation methods. Located in Honolulu County, Hawaii, this benchmark contributes to the geodetic infrastructure supporting survey work across the Hawaiian Islands. The coordinates 21.54694°N, 158.10000°W identify its position within the national coordinate system. Verification and documentation of such control points remain essential for maintaining the integrity of the National Spatial Reference System. Surveyors and engineers rely on properly maintained benchmarks for accurate positioning in construction, infrastructure development, and geographic information system applications. Current condition assessment and coordinate validation of existing trigonometric stations ensure continued utility for professional surveying practice.
