The Public Land Survey System (PLSS) and other special surveys within, and exclusions from, public domain lands, are shown on USGS quadrangle maps. This portrayal shows first-level subdivisions and is intended to be used as a reference grid, not as an identification of ownership or parcel boundaries.
This data was digitized from USGS 1:24,000 Topographic Maps.
The public domain includes the land ceded to the Federal Government by the Thirteen Original States and acquired from native Indians and foreign powers. The surveys of the public domain can be classified into the following general types:
Land Grants - Land grants were conferred on individuals by a predecessor government and were never part of the public domain.
PLSS Area - The rectangular system of surveys was developed to divide the public lands for disposal by the government. This survey system typically divides the land into 6-mile square townships, which are further subdivided into 1-mile square sections, although there are departures from this regular system.
Private Surveys - The government is responsible for conducting these surveys, but some land has been surveyed by private surveyors who have extended the PLSS using the rectangular system of surveys.
Special Survey Areas - Some land was disposed of by special surveys that were usually the result of acts of Congress. These include U.S. surveys, homestead entry surveys, Indian allotments, and donation land claims. Special survey areas are not subdivided by rectangular surveys.
Waterbodies - Navigable water ways and water bodies over 50 acres were not subject to disposal and were not subdivided by surveys.
Reservations - Other land was "reserved" by the Federal Government and not subject to disposal, such as national parks, forests, and Indian reservations. These lands may contain subdivision lines if the reservations were established after the area had been surveyed.
For additional background information on the PLSS and its associated types of survey areas, lines, and corners, see Appendix 3.11.A. in the document "Part 3: Attribute Coding: Standards for Digital Line Graphs" available at http://nationalmap.gov/standards/pdf/3dlg0798.pdf
