This is a triangulation (trig) station within the National Geodetic Survey's network, a fundamental component of the United States' geodetic infrastructure. Trig stations serve as primary control points for establishing accurate horizontal positions and elevations across the country. This particular benchmark is located near Smithfield, West Virginia, at coordinates 39.49950° North latitude and 80.56436° West longitude. As a trig point, it was historically established as part of a network designed to provide precise spatial reference data for mapping, surveying, and engineering projects. Verification and documentation of such control points remain essential for maintaining the integrity of the national spatial reference system. Surveyors and geospatial professionals rely on benchmarks like this to ensure accuracy in cadastral surveys, infrastructure development, and scientific applications. Locating and confirming the condition of existing NGS monuments contributes valuable information to the geodetic community.
