This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental geodetic control framework for the United States. Triangulation points serve as reference stations for surveyors, engineers, and mapping professionals conducting precise positional work across their respective regions. Located near Waipahu on the island of Oahu, Hawaii, this benchmark contributes to the geodetic control network for the Hawaiian Islands. The station's coordinates are referenced within the NGS system and provide a documented reference point for local survey activities and geospatial projects. Verification and proper documentation of such control points remain essential for maintaining the integrity of survey networks, ensuring consistency in mapping projects, and supporting infrastructure development. Regular examination and monumentation records help preserve these critical reference stations for future surveying applications.

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.
