This triangulation station is part of the National Geodetic Survey's primary control network, which establishes the fundamental geodetic framework for the United States. Trig stations of this class serve as reference points for surveying, mapping, and engineering projects across the nation. Located at coordinates 21.56731°N, 158.26021°W in the Hawaii region, this point contributes to the spatial accuracy of surveys in the Pacific area. The elevation value has not been recorded in available documentation. As with all NGS benchmarks, verification and proper documentation of such control points remain essential for maintaining the integrity of the national coordinate system and supporting accurate positioning for civil infrastructure, cartography, and scientific applications. Surveyors and geodesists are encouraged to report observations or recovery status to the NGS for network maintenance purposes.

Geodetic context in United States

The national geodetic reference in United States is maintained by National Geodetic Survey (NGS). The active datum is NAD83(2011) / NATRF2022 (active). Coordinates shown on this page are expressed in WGS84 (ETRF/ITRF-compatible) which is directly usable in most modern GNSS receivers. For cadastral work in United States you may need to convert to the local datum using the Coordinate Hub.

Is this point verified and usable for professional surveying?

This record has been community-verified 0 times. Data quality depends on the source: NGS and official national agency points are typically centimetre-accurate, OpenStreetMap survey points are metre-accurate, and GeoNames topographic landmarks (peaks, hills) are reference-grade only. Always cross-reference with the original agency datasheet before using this point for cadastral, legal, or safety-critical work.

Original source: this record was imported from ngs_public. Always refer to the original datasheet for the most up-to-date and authoritative data.
