This triangulation station is part of the NGS national geodetic network, which establishes the foundational control points for surveying and mapping activities across the United States. As a trig point, this station served as a precisely positioned reference location used in triangulation surveys to extend horizontal control networks and support subsequent cadastral, engineering, and cartographic projects. Located near Dover, New Hampshire at coordinates 43.12000° N, 70.82806° W, this benchmark represents a key element in regional geodetic infrastructure for the northeastern United States. Trig stations of this type were historically occupied with surveying instruments to measure angles and distances, enabling surveyors to determine positions of other points with high precision. The documentation and verification of such control points remain valuable for modern surveying professionals conducting boundary surveys, construction projects, and geographic information systems work. Maintaining accurate records of these established monuments supports continuity in surveying practice and ensures reproducibility of measurements across generations of surveying work.
