PLSS

http://gis.nwcg.gov/giss_2006/cd_contents.html

This Public Land Survey System (PLSS) of the United States is an example of a systematic land partitioning system.  The PLSS surveys and identifies parcels of land for ownership using a series of base lines, principal meridians, and initial points making a grid.  The PLSS is broken down into townships (six mile incremental divisions parallel to the base line) and ranges (six mile incremental divisions parallel to the principal meridian) resulting in a congressional township (intersection of townships and ranges).  These are then divided into sections (one mile square parcels of land) which are around 640 acres.  Finally, the PLSS sections are split into plats, displaying individual parcels of land.
