This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Trig stations of this type serve as precisely positioned reference points used to support cadastral surveys, engineering projects, and geographic data collection across their service areas. Located at 21.52806° N, 158.22861° W, this point lies within United States territory in the Pacific region. As a component of NGS's distributed network, it contributes to the overall accuracy and consistency of positional data in its region. Verification and documentation of such benchmarks remain essential for maintaining geodetic infrastructure integrity. Surveying professionals rely on confirmed control points to establish local coordinate systems and validate measurement accuracy. Recording the current condition and accessibility of existing stations supports continued utility of the national geodetic framework for both public works and private surveying applications.

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.
