The ‘PLS’ layer is a polygon coverage depicting the township, range and sections contained in the Public Land Survey System grid for the State of California. Townships are roughly six miles square, and are numbered north and south from an established baseline. Likewise, ranges are numbered east and west from an established meridian. California uses three baseline/meridians, these being Humboldt, Mt. Diablo, and San Bernardino, abbreviated HB&M, MDB&M, and SBB&M. Township and range values are combined in the redefined item TOWN-RANGE to facilitate dissolve and dropline functions.
