W 451 — NGS DJ8227 — Aurora, US

This triangulation station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Trig stations serve as primary control points for surveying and mapping activities, providing accurately determined positions that support both public and private surveying operations. Located near Aurora, Colorado at latitude 39.77023° and longitude -104.82605°, this benchmark contributes to the horizontal control network in the Denver metropolitan region. Such points are essential references for engineers, surveyors, and cartographers undertaking projects requiring precise geographic positioning. The documentation and verification of existing benchmarks remains valuable to the surveying profession. These reference points facilitate compliance with accuracy standards, enable quality assurance in surveying work, and support long-term spatial data consistency across regions. Current position recovery and condition assessment of historic control points strengthen the overall reliability of geodetic infrastructure.
