STATE — NGS RD3203 — Portland, US

This triangulation station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Located near Portland, Oregon at coordinates 45.61441° N, 122.67819° W, this trig point serves as a reference control station for surveying and mapping operations across the region. Triangulation stations of this type historically provided accurate horizontal positioning data essential for large-scale surveying projects and the development of accurate maps. Modern surveyors and geodesists continue to verify and document such points to maintain the integrity of the national control network and support precision engineering, construction, and land surveying activities. Accurate location and elevation documentation of established benchmarks remains valuable for long-term geodetic monitoring and as tie points for contemporary surveying methodologies. The continued maintenance and verification of NGS control points supports the surveying profession's operational standards.
