This trigonometric station is part of the National Geodetic Survey's horizontal control network, which establishes the foundational geometric framework for mapping and surveying throughout United States territory. Located in the Saint Thomas-Saint John District of the United States Virgin Islands, this point serves as a reference for determining accurate horizontal positions in the region. The negative ellipsoidal elevation indicates a subsurface or marine reference datum relative to the WGS 84 ellipsoid. Trig stations of this classification provide essential control points for cadastral surveys, engineering projects, and geographic information systems. Regular verification and documentation of such benchmarks ensures the integrity of the geodetic network and supports reliable spatial referencing for both public works and private surveying activities. Maintaining accurate records of control point locations and elevations remains critical to surveying infrastructure in US territories.
