This triangulation station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Trig stations serve as control points for surveying, mapping, and engineering projects by providing precisely determined horizontal positions within a continuous network. Located near Chicago, Illinois at coordinates 41.94441° N, 87.82660° W, this benchmark contributes to regional survey infrastructure. Triangulation stations historically formed the backbone of large-scale positional control before satellite-based methods became primary. Verification and documentation of such points remain valuable for surveying professionals who rely on legacy networks, particularly for local projects, boundary determinations, and historical survey reconstruction. Maintaining accurate records of these monuments supports continuity in geodetic reference systems and facilitates professional surveying practice.

Geodetic context in United States

The national geodetic reference in United States is maintained by National Geodetic Survey (NGS). The active datum is NAD83(2011) / NATRF2022 (active). Coordinates shown on this page are expressed in WGS84 (ETRF/ITRF-compatible) which is directly usable in most modern GNSS receivers. For cadastral work in United States you may need to convert to the local datum using the Coordinate Hub.
