This trigonometric station is part of the National Geodetic Survey's network of reference points establishing the fundamental control framework for surveying and mapping across the United States. Located near Portland, Oregon at latitude 45.54828° N and longitude 122.56003° W, this trig point serves as a horizontal control station for local and regional surveys. Trigonometric stations of this type are monumented positions whose coordinates have been precisely determined through geodetic measurements, enabling surveyors and engineers to reference their work to the national datum. Such control points support land surveying, engineering projects, mapping initiatives, and geographic information systems. Verification and documentation of these reference points remain valuable for maintaining positional accuracy and continuity in surveying practice, particularly as older monuments may be disturbed or destroyed through development or natural processes.
