22 — NGS RD0621 — Vancouver, US

This trigonometric station is part of the National Geodetic Survey's network, which establishes and maintains the horizontal and vertical control framework essential to surveying and mapping throughout the United States. Trig stations serve as precisely positioned reference points from which surveyors can measure distances and angles to establish property boundaries, conduct engineering projects, and support cartographic work. Located near Vancouver, Washington at coordinates 45.62306°N, 122.67278°W, this benchmark contributes to regional geodetic infrastructure in the Pacific Northwest. The point's documented position enables surveyors to tie local work into the national coordinate system with known accuracy. Verification and careful documentation of such control points remains critical for maintaining surveying standards and ensuring consistency across projects over time. The archived record of this station's characteristics and location preserves its utility as a reference for future surveying activities.
