This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal control framework for the United States. Triangulation (trig) stations serve as high-precision reference points used to support surveying, mapping, and engineering projects across their respective regions. Located at coordinates 21.58161°N, 158.17372°W, this point lies within United States territory in the Pacific. Trig stations of this type typically occupy elevated or strategically positioned locations to facilitate intervisibility with other control points, enabling accurate distance and angle measurements across networks. Documentation and verification of such benchmarks remain essential for maintaining geodetic infrastructure integrity. Surveyors and engineers rely on these established positions for local and regional projects. Recording and preserving the precise locations and characteristics of control points ensures long-term usability and supports the continuity of accurate spatial reference frameworks.

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.
