This is a triangulation (trig) station within the National Geodetic Survey's network, a foundational system of control points establishing the geometric framework for surveying and mapping across the United States. Located near Kennebunk, Maine at coordinates 43.35463° N, 70.50559° W, this point serves as a reference for horizontal positioning and datum definition in its region. Trig stations function as precise monuments from which surveyors establish local surveys, verify instrumental accuracy, and maintain consistency across mapping projects. The NGS network integrates thousands of such points into a coherent geodetic datum, enabling accurate property delineation, infrastructure development, and geographic data compilation. Verification and documentation of benchmark locations remain critical for surveyors and engineers requiring reliable positional references. Confirming monument stability, accessibility, and coordinate accuracy supports ongoing surveying operations and ensures spatial data integrity throughout Maine's coastal region.
