PLSS, Public Land Survey System, maps use a system based on the grid of townships and ranges and break up the area being looked at into those different sections.  It's used in order to divide up public land owned by the federal government. The above map shows how the PLSS is used in order to divide up the land in Franklin County, Alabama.
