D 452 — NGS DJ8224 — Denver, US

This triangulation station is part of the NGS network, which establishes and maintains the foundation for precise horizontal control across the United States. Trig stations serve as primary reference points for surveying, mapping, and engineering projects requiring high-accuracy positioning. Located near Denver, Colorado, at coordinates 39.77601°, -104.93318°, this benchmark contributes to regional geodetic infrastructure supporting both public and private surveying activities. Trig points are typically monumented stations used in classical triangulation networks to define positions with rigorous geometric relationships to other stations. Verification and documentation of such control points remains essential for maintaining the integrity of the national geodetic datum and ensuring consistency in land surveys, infrastructure development, and geospatial data accuracy. Regular inspection and reobservation of these stations help preserve their utility for future surveying projects.
