PLSS stands for Public Land Survey System, these maps are subdivision of cadastral maps. It is sometimes referred to as rectangular survey system. A PPLS map is a map that divides public domain land and is the first mathematic solution to divvying up land in the United States. The Federal government has all the maps on record which are for public viewing. The map above is of a county in Wisconsin. The perfectly divided squares with very little variation can clearly be seen.
