This triangulation station is part of the National Geodetic Survey's trigonometric network, which establishes the foundational control framework for surveying and mapping throughout the United States. Located at coordinates 21.56356°N, 158.24529°W in Hawaii, this trig point serves as a horizontal reference for regional geodetic surveys and property boundary determinations. Trigonometric stations of this type were historically established through careful angular measurements and distance observations to create networks of known positions. The NGS maintains records of such benchmarks to support surveying professionals, cartographers, and infrastructure development projects. Verification and documentation of existing control points remain essential for ensuring accuracy in modern surveying work and for validating legacy survey data. The elevation at this location was not recorded in available documentation.

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.
