LEM 2 — NGS RD2891 — Multnomah County, US

This trigonometric (trig) station is part of the National Geodetic Survey's network, which establishes the fundamental control 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 conduct accurate measurements and spatial analysis. Located in Multnomah County, Oregon, this benchmark contributes to the geodetic infrastructure of the Pacific Northwest region. The station's coordinates have been determined and registered within the NGS database, providing a stable reference for professional surveyors conducting boundary, engineering, and mapping work in the area. Verification and documentation of such control points remain essential for maintaining the integrity of the national spatial reference system. Regular confirmation of benchmark stability ensures continued utility for contemporary surveying practices and supports the long-term reliability of georeferenced data throughout the region.
