This trigonometric station is part of the NGS network, which provides the foundational geodetic control for surveying, mapping, and engineering projects throughout the United States. Located in Multnomah County, Oregon, near coordinates 45.57933°N, 122.49459°W, this trig point serves as a reference for establishing accurate horizontal and vertical positioning data in the region. Trig stations like this one function as monumented control points, enabling surveyors and geodesists to tie local surveys to the national datum and maintain consistency across large-scale spatial projects. The ellipsoidal elevation of -2.5 meters indicates positioning relative to the ellipsoid model rather than mean sea level. Documentation and periodic verification of such benchmarks remain essential for maintaining the integrity of geodetic networks, supporting public works, land surveying, and scientific research requiring reliable spatial reference data.
