This trigonometric station is part of the National Geodetic Survey's comprehensive network of control points that form the foundation of the United States' geodetic infrastructure. Located in Baltimore County, Maryland, at coordinates 39.22296° north latitude and 76.70004° west longitude, this trig point serves as a primary reference for surveying and mapping activities throughout the region. Trigonometric stations function as high-precision spatial reference markers, enabling surveyors to establish accurate horizontal and vertical control for local projects. The ellipsoidal elevation of -15.1 meters indicates positioning relative to the reference ellipsoid rather than mean sea level. Regular verification and documentation of such benchmarks ensures the integrity of the geodetic network and supports professional surveying standards. These control points remain essential infrastructure for engineering, construction, and spatial data applications.
