This triangulation station is part of the NGS network, which establishes the fundamental geodetic control framework for the United States. As a trig point, this station served as a control vertex for surveying networks, enabling precise horizontal positioning for mapping and engineering projects. Located at coordinates 21.44084°N, 158.18931°W in US territory, the point contributes to regional positional reference infrastructure. The elevation data remains unrecorded in available documentation. Verification and documentation of such control points remain valuable for maintaining geodetic integrity, particularly as surveying methodologies evolve and national coordinate systems are refined. Surveyors and mapmakers continue to reference these established stations for ensuring consistency and accuracy in spatial data collection and project execution across jurisdictions.

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.
