Aliquot Parts - Sections were then further subdivided into smaller pieces, such as halves and quarters, while still (generally) keeping the land in a square.Section Number - Townships were then further broken down into thirty-six sections of 640 acres each (one square mile) called sections, which were numbered with reference to the baseline and meridian line.Example: Township 3 North, Range 9 West, 5th Principal Meridian identifies a specific township that is 3 tiers north from the baseline and 9 tiers west (Range) of the 5th Principal Meridian. A Township is identified by this relationship to a base line and a principal meridian. The east/west identification is known as the Range. Townships are then numbered from the base line north and south and then from the meridian line east and west. Township and Range - Townships, a major subdivision of public lands under the rectangular survey system, measure approximately six miles on a side (thirty-six square miles).An online table shows PLSS Cadastral National Spatial Data Infrastructure (CadNSDI) data set availability. Use the "Add Data" tool at the top of the map.įor GIS users, PLSS data layers are available through the BLM’s REST service endpoint. The National Map Viewer displays "BLM Public Land Survey System (PLSS)". US Topo maps published 2013-present have a Public Land Survey System layer that can be turned on and off. US Topo maps published 2009-2012 do not include any PLSS data. PLSS was created to divide parcels of public land it is not useful for the accurate location of points and should not be confused with coordinate systems like latitude/longitude, UTM, or the State Plane Coordinate System.įor states that have Public Land Surveys:Īlmost all historical topographic maps (1884-2006) include PLSS tic marks or gridlines. Sections can be further subdivided into quarter sections, quarter-quarter sections, or irregular government lots. Townships are subdivided into 36 one-mile-square sections. The PLSS typically divides land into 6-mile-square townships. PLSS surveys, which are available for portions of land in 30 southern and western states, are made by the Bureau of Land Management (BLM). The Public Land Survey System (PLSS) is a way of subdividing and describing land in the United States.
