This triangulation station represents part of the National Geodetic Survey's fundamental control network, which establishes the geometric foundation for mapping, surveying, and geographic information systems throughout the United States and its territories. Located in the Saint Thomas-Saint John District of the United States Virgin Islands, this trig point serves as a horizontal control reference for surveying activities across the eastern Caribbean region. Triangulation stations of this type were historically integral to precise geodetic networks before satellite-based positioning systems. Contemporary surveyors and GIS professionals rely on verification and documentation of such benchmarks to maintain spatial reference accuracy, establish historical geodetic frameworks, and support land records systems. The precise coordinate data enables surveyors to conduct property surveys, infrastructure projects, and cartographic work with established accuracy standards relative to the national geodetic datum.
