J 3 — NGS TU0579

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.
