S 452 — NGS DJ8165 — Denver, US

This triangulation station is part of the NGS network, which establishes and maintains the primary geodetic framework for the United States. Located near Denver, Colorado at coordinates 39.78383° N, 104.99173° W, this trig point serves as a control station for surveying and mapping operations across the region. Triangulation stations function as monumented reference points with precisely determined horizontal positions. They enable surveyors to establish local control networks and verify survey accuracy for engineering, cadastral, and scientific projects. The NGS network integrates these points into the National Spatial Reference System, supporting infrastructure development, land management, and scientific research throughout the country. Verification and documentation of such benchmarks remain essential to maintaining geodetic accuracy. These points provide the geometric foundation upon which modern surveying, GIS applications, and civil engineering projects depend.
