This trigonometric station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental control framework for surveying and mapping activities throughout the United States and its territories. Located in the Saint Thomas-Saint John District of the United States Virgin Islands, this point serves as a reference station for precise horizontal control. The ellipsoidal elevation of 6.4 meters reflects its position in this Caribbean locality. Trigonometric stations of this type were historically established to provide accurate positional references for subsequent survey work, facilitating reliable cadastral mapping, infrastructure development, and geographic information systems. Modern verification and documentation of such benchmarks remain valuable for practitioners requiring traceable geodetic control, particularly in areas where contemporary survey networks may reference legacy horizontal control. Maintaining accurate records of these stations supports continuity in surveying practice and regional geographic data integrity.
