Computations of traverse lines, eccentric stations, triangle sides, and geographic positions [Board of Harbor and Land Commissioners of Massachusetts]
Computations of traverse lines, eccentric stations, triangle sides, and geographic positions, 1890-1915.
Call no.: EN3.03/646X
Scope and Content: To establish accurate Massachusetts town boundaries, and eventually interstate boundaries as well, beginning in 1885 the Topographical Survey Commission (replaced in this function in 1901 by the Board of Harbor and Land Commissioners) sent out field teams to establish and describe triangulation stations and to set monuments designating boundary lines. These volumes of computations of traverse lines, eccentric stations, triangle sides, and geographic positions are based on field notebooks of the survey teams. Computations were verified, adjusted, and prepared by the U.S. Coast and Geodetic Survey.
Arrangement: Arranged chronologically, thereunder by locality
