12 U — NGS MB3157 — Valley View, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational reference system for surveying and mapping throughout the United States. Located near Valley View, Ohio, this trig point serves as a precise horizontal and vertical control station for regional geodetic work. Triangulation stations of this type were established to create a framework of accurately positioned points across the country. These monuments enable surveyors, engineers, and cartographers to reference their local measurements to a consistent national datum. The ellipsoidal elevation of 149.4 m reflects the point's vertical position relative to the reference ellipsoid. Verification and documentation of such control stations remains essential for maintaining the integrity of the geodetic network, supporting cadastral surveys, infrastructure projects, and scientific applications requiring precise spatial reference.
