U 451 — NGS DJ8159 — Aurora, US

This triangulation station is part of the National Geodetic Survey's network, which serves as foundational control for precise surveying and mapping activities across the United States. Located near Aurora, Colorado, at coordinates 39.76735°N, 104.80043°W, this trig point contributes to the horizontal geodetic framework essential for large-scale engineering projects, land surveying, and geographic information system development. Triangulation stations function as monumented reference points established through precise angular measurements between distant locations. Such points provide surveyors and engineers with reliable datum markers for local surveys and coordinate transformations. The preservation and verification of benchmark data ensures continuity in geodetic standards and supports accurate redetermination of property boundaries and infrastructure alignment. Documentation of this point's condition and accessibility aids the surveying community in maintaining the integrity of regional control networks. Professionals undertaking precise positioning work should verify current monument status before field operations.
