This triangulation (trig) station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental geodetic control for the United States. Located near Chicago, Illinois, at coordinates 41.88928°N, 87.61121°W, this point serves as a reference marker for surveying and mapping operations across its region. Trig stations function as precisely positioned control points that surveyors and cartographers use to establish accurate horizontal positions for subsequent surveys and mapping projects. The NGS network provides essential infrastructure supporting civil engineering, land surveying, and geographic information systems throughout the country. Documentation and verification of benchmark locations remain important for maintaining the integrity of the geodetic reference system. Even when elevation data is not recorded, the horizontal coordinates provide valuable survey control. Professional surveyors rely on these established points to ensure consistency and accuracy in their work.
