This trigonometric station is part of the National Geodetic Survey's network, which establishes the fundamental reference framework for surveying and mapping throughout the United States. Trig stations serve as primary control points for horizontal positioning, enabling surveyors and cartographers to reference local surveys to the national datum. Located near Dundalk, Maryland, in the Baltimore metropolitan region, this benchmark occupies a strategic position within the mid-Atlantic geodetic infrastructure. The ellipsoidal elevation of -6.6 meters reflects the point's position relative to the WGS84 reference ellipsoid. Verification and documentation of such control points remain essential for maintaining survey accuracy, supporting infrastructure development, and ensuring consistency in geospatial data collection across jurisdictions. Regular confirmation of monument condition and coordinate values preserves the utility of the national control network for contemporary surveying operations.
