This triangulation station is part of the National Geodetic Survey's network of control points that establish the geometric framework for surveying and mapping across the United States. Trig stations serve as precisely positioned reference points for horizontal control, enabling surveyors and cartographers to tie local measurements into the national coordinate system. Located near Portland, Oregon, at coordinates 45.54222°N, 122.69500°W, this point contributes to the geodetic infrastructure supporting transportation, land records, construction, and geographic information systems throughout the Pacific Northwest region. Like other NGS monuments, this station's documented position allows surveyors to verify their own measurements and maintain consistency in cadastral and engineering surveys. Periodic reoccupation and verification of such benchmarks remains valuable for quality assurance in surveying practice and for detecting any ground movement or monument disturbance over time. Professional surveyors rely on the accessibility and reliability of these reference points.
