U 103 — NGS PY0163 — Gallatin County, US

This triangulation station is part of the NGS network, which serves as the fundamental framework for geodetic control across the United States. Trig stations like this point establish precise horizontal positions essential for surveying, mapping, and engineering projects. Located in Gallatin County, Montana at coordinates 44.97806°, -111.08222°, this benchmark contributes to the geospatial reference system that supports both public infrastructure and private surveying efforts. Triangulation stations were historically observed and occupied to create interconnected networks of known positions. Modern surveyors rely on documented benchmarks to verify equipment, establish local control, and ensure consistency across projects. Verifying and maintaining records of such points preserves the integrity of the geodetic datum and facilitates accurate spatial referencing. For professionals conducting fieldwork in the region, confirming the continued stability and accessibility of established control points remains valuable for quality assurance and regulatory compliance.
