WET — NGS TU1591

This trigonometric station is part of the National Geodetic Survey's network, which forms the foundation of the United States' geodetic reference system. Trig stations like this serve as primary control points for surveying, mapping, and engineering projects across the nation. Located in Hawaii at coordinates 21.57984°N, 158.25200°W, this benchmark contributes to the horizontal control network essential for accurate positioning work. Such stations are monumented to ensure permanence and enable rediscovery by surveyors and geodesists conducting subsequent measurements. Verification and documentation of trig stations maintain the integrity of the geodetic framework. Even when elevation data remains unretrieved, the horizontal coordinates provide valuable reference geometry for professional surveying activities. These monuments represent significant infrastructure investments in positional accuracy and remain important resources for cadastral, construction, and scientific applications requiring reliable control.
