30 AY — NGS MB3239 — Euclid, US

This triangulation station is part of the National Geodetic Survey's foundational control network, which establishes the geometric framework for surveying, mapping, and infrastructure development across the United States. Located near Euclid, Ohio, in Cuyahoga County, the point occupies a position of strategic importance within the regional geodetic infrastructure of northeastern Ohio. As a trigonometric station, this benchmark serves as a primary control point for horizontal positioning in surveying operations. The documented ellipsoidal elevation of 175.1 meters provides vertical control data essential for engineering projects, flood modeling, and precise geographical reference. Regular verification and maintenance of such points ensures the integrity of the nation's spatial reference system. Surveyors and engineers rely on accurate documentation of these stations for boundary determination, construction layout, and navigation applications throughout the region.
