This triangulation station is part of the National Geodetic Survey's network of control points that form the foundation of horizontal geodetic control across the United States. Triangulation stations, commonly known as trig points, were historically observed and incorporated into the national network to establish accurate horizontal positions for mapping, surveying, and engineering applications. Located near Evanston, Illinois at coordinates 42.04861° north latitude and 87.68500° west longitude, this point serves the Chicago metropolitan region. As a component of NGS's broader geodetic infrastructure, this benchmark supports large-scale surveying projects and spatial data collection. Verification and documentation of such control points remain valuable for surveyors, engineers, and geographic information specialists who rely on accurate reference frameworks for professional work. Maintaining records of these monuments ensures continuity of geodetic standards across generations of surveying practice.
