  Description:
    Abstract:
      This data set contains section polygons from the Illinois Public Land Survey System.

      The polygons are coded with values for principal meridian, section number, and township and range numbers and direction.

      Refer to the parent metadata document for complete information.

    Purpose:
      These data are appropriate for use in local and regional thematic analysis. The data are not appropriate as a geodetic, legal or engineering base. The data set was originally created for the purpose of producing maps of well locations in Illinois for geologic research by the ISGS and others. It serves as an important base cartographic element for many types of maps and has been widely distributed and used outside the ISGS. The data set was not and is not intended as a substitute for surveyed locations, such as can be determined by a registered Public Land Surveyor. Although useful in a GIS as a reference base layer for maps, the data set has no legal basis in the definition of boundaries or property lines.
