This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational control for surveying and mapping throughout the United States. Located at coordinates 21.45021°N, 158.19537°W in the Hawaiian Islands region, this trig point serves as a horizontal and vertical reference for local and regional surveys. Triangulation stations of this type are typically established on elevated terrain to provide intervisible control points across geographic areas. The ellipsoidal elevation of 18.4 meters reflects the point's position within the State Plane Coordinate System framework. Such marks are critical infrastructure for cadastral surveys, engineering projects, and maintaining spatial consistency across jurisdictions. Periodic verification of benchmark condition and coordinate accuracy ensures the integrity of the geodetic network. Documentation of these reference points supports professional surveying practice and spatial data standards essential to public and private sector operations.

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.
