N 13 — NGS MB1275 — Rocky River, US

This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental geodetic control framework for the United States. Trig stations serve as monumented reference points for horizontal position control, enabling surveyors and engineers to accurately establish local and regional coordinate systems. Located near Rocky River in northern Ohio, this point contributes to the broader NGS network extending across the country. As a triangulation station, it was historically observed as part of classical surveying campaigns to create geometric networks spanning large areas. The documentation and verification of such control points remain valuable for modern surveying practices, including boundary surveys, infrastructure development, and geospatial applications. Maintaining current information about these monuments—including their physical condition and coordinate accuracy—supports professional surveyors in accessing reliable reference data for their projects and ensures the integrity of the nation's geodetic infrastructure.
