This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational horizontal and vertical control framework for the United States. Trigonometric stations serve as primary reference points for precise surveying, mapping, and engineering projects across their respective regions. Located at coordinates 21.56913°N, 158.26262°W, this benchmark lies within Hawaiian territory. Triangulation stations of this type historically provided essential ground control for larger-scale geodetic surveys and continue to support modern positioning efforts. Verification and documentation of existing benchmarks remain valuable for surveyors and geospatial professionals who require reliable reference points for local projects and coordinate system validation. Recording the current condition and accessibility of such stations helps maintain the integrity of the nation's geodetic infrastructure and supports continuity in surveying practices.

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.
