VANCOUVER ST JAMES CH — NGS RD3339

This triangulation station is part of the National Geodetic Survey's control network, which establishes the fundamental geometric framework for surveying and mapping throughout the United States. Trig stations serve as precisely positioned reference points for horizontal control, enabling surveyors to determine locations and distances with documented accuracy. Located near Vancouver, Washington, at coordinates 45.63052° N, 122.67309° W, this point contributes to regional geodetic infrastructure in the Pacific Northwest. The station's position within the NGS network makes it valuable for boundary surveys, construction projects, and cartographic applications requiring reliable horizontal reference data. Verification and documentation of such control points remain essential for maintaining the integrity of the national geodetic datum. Surveying professionals rely on these established positions as foundational references for local surveys and spatial projects. Current condition assessments and coordinate confirmation ensure continued utility of this benchmark within the broader survey control network.
