KAENA POINT RADAR DOME — NGS TU1575

This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational control framework for surveying and mapping throughout the United States. Trigonometric stations serve as precise reference points for terrestrial surveys, enabling accurate determination of positions and elevations across regions. Located at coordinates 21.56227°N, 158.24211°W in US territory, this benchmark occupies a position in the Pacific region. As a trig point, it was historically established to support large-scale surveying projects requiring intervisible stations and precise horizontal control. Verification and documentation of such control points remain essential for modern surveying operations, geographic information systems, and infrastructure development. The maintenance of accurate geodetic records ensures that contemporary surveyors can rely on established reference standards for their work, supporting both public and private surveying endeavors across generations of use.
