Borden Base Line

The Borden Base Line is a historic survey line (7.42 miles, 39,009.73 feet (11,890.17 m) long) running north/south through Hatfield and South Deerfield, Massachusetts. It was completed in 1831, and is now on the List of historic civil engineering landmarks. The base line measurement was the first project of its kind undertaken in America, and essential for Massachusetts' pioneering Trigonometrical Survey, performed under chief engineer Robert Treat Paine. Its careful measurement was critical, since the accuracy of the whole triangulation network depended on it.
