This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational geodetic control for the United States. Triangulation stations serve as fixed reference points for surveying, mapping, and engineering projects requiring precise horizontal positioning. Located in the Kapolei area of Oahu, Hawaii, at coordinates 21.33906°N, 158.05308°W, this trig point contributes to Hawaii's surveying infrastructure. Such stations are typically monumented markers—often brass disks or stone cairns—that survive decades or longer, providing surveyors and engineers with reliable control points for cadastral surveys, construction projects, and spatial data development. Documentation and periodic verification of these monuments ensure their continued utility. The NGS maintains records of station coordinates, descriptions, and recovery histories to support professional surveying activities throughout Hawaii and the Pacific region. This point's inclusion in the geodetic network reflects its role in supporting accurate spatial referencing across the islands.

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.
