This triangulation station is part of the National Geodetic Survey's network, which establishes the geometric foundation for surveying and mapping activities throughout the United States. Trigonometric (trig) stations serve as monumented reference points used to control and validate horizontal positioning for local surveys and cartographic work. Located near Columbia, Maryland, at coordinates 39.21139° north latitude and 76.70194° west longitude, this point contributes to regional geodetic control in the Mid-Atlantic area. The exact elevation has not been recorded in available documentation. Verification and documentation of such reference points remain essential for maintaining survey accuracy and data consistency across jurisdictional boundaries. Professional surveyors rely on properly cataloged benchmarks to tie their local measurements into the broader national coordinate system, ensuring spatial data interoperability and long-term archival value.
