V 451 — NGS DJ8158 — Aurora, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the official horizontal geodetic control framework across the United States. Trigonometric or "trig" stations serve as primary reference points for surveying, mapping, and engineering projects that require high-precision positional accuracy. Located near Aurora, Colorado, at coordinates 39.76957° N, 104.81257° W, this benchmark contributes to regional geodetic coverage in the Front Range area. Trig stations of this classification typically occupy elevated or strategically visible locations to facilitate sightings between multiple control points. Documentation and verification of such reference points remain essential for maintaining the integrity of the national geodetic datum. Surveyors and engineers rely on these established positions for property boundary determination, infrastructure development, and cartographic applications. Regular confirmation of benchmark stability and accessibility ensures continued utility within the broader geodetic network.
