This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping across the United States. Located near Dundalk, Maryland, at coordinates 39.31786°N, 76.51906°W, this trig point serves as a reference station for precise horizontal positioning. Triangulation stations of this type are monumented locations used to support geodetic measurements and provide ground control for surveying operations, engineering projects, and geographic information systems. The NGS network enables surveyors and mapping professionals to conduct work with consistent, traceable accuracy relative to the national datum. Documentation and verification of benchmark locations remain essential for maintaining the integrity of the geodetic infrastructure. Even when elevation data is unavailable, the horizontal coordinates provide valuable control for regional surveying efforts and help preserve the continuity of the national geodetic framework for future surveying professionals.
