This trigonometric station is part of the National Geodetic Survey's monumented network, which establishes the fundamental geometric framework for surveying and mapping across the United States. Trigonometric points serve as precisely positioned reference stations used to control and verify large-scale surveys, engineering projects, and geospatial data collection. Located in the Chicago, Illinois area, this benchmark is situated within the densely developed metropolitan region of northern Illinois, where accurate geodetic control supports infrastructure development and land surveying operations. The ellipsoidal elevation of 161.0 meters is referenced to the current geodetic datum. Documentation and verification of such control points remains essential for surveying professionals, as these monuments provide reliable positional references for boundary surveys, construction layout, and geographic information systems. Maintaining accurate records of benchmark locations and their coordinate values ensures consistency in surveying work across jurisdictions and time.
