This triangulation station is part of the NGS network, which maintains the foundational horizontal geodetic control for the United States. As a trig point, it served historical surveying campaigns to establish accurate positions across broad areas through intervisible networks of elevated stations. The coordinates place this benchmark in Hawaii, where such points were essential for mapping the archipelago and supporting subsequent survey work. Trig stations remain valuable reference monuments for surveyors and engineers conducting local surveys, boundary work, and engineering projects. Verification and documentation of existing benchmarks helps preserve institutional knowledge of control networks and enables professionals to assess point condition, accessibility, and suitability for contemporary applications. This point's elevation data should be sought through NGS records to complete its characterization as a reference monument.

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.
