Taylor Grazing Act Districts

Frequently-asked questions:

What does this data set describe?

Taylor Grazing Act Districts

A district that was identified based on the Taylor Grazing Act of 1934 which regulates grazing on federal public lands. Lands within a Taylor Grazing Act district can be vacant, unappropriated, and unreserved lands from any part of the public domain of the United States (exclusive of Alaska), which are not in National Forests, National parks and National Park Service monuments, Indian reservations, revested Oregon and California Railroad grant lands, or revested Coos Bay Wagon Road grant lands, and which are chiefly valuable for grazing and raising forage crops;  provided, that no lands withdrawn or reserved for any other purpose shall be included in any such district. Permits are given for grazing privileges.

  5. What is the general form of this data set?

    Geospatial data presentation form: vector digital data

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • G-polygon (0)
      • String (0)
      • String (0)
      • G-polygon (0)

    2. What coordinate system is used to represent geographic features?

      The map projection used is Transverse Mercator.

      Projection parameters:
      Scale factor at central meridian: 0.999400
      Longitude of central meridian: -119.000000
      Latitude of projection origin: 37.000000
      False easting: 500000.000000
      False northing: 1500000.000000

      Planar coordinates are encoded using coordinate pair.
      Abscissae (x-coordinates) are specified to the nearest 0.000100.
      Ordinates (y-coordinates) are specified to the nearest 0.000100.
      Planar coordinates are specified in meters.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

Why was the data set created?

The standard will facilitate portrayal, queries, and use of this data set.  This information is of particular use to the Rangeland community and is required for some processes.  Once this spatial data is created it may be possible to link it with the Rangeland Administration System (RAS) to help determine how monies are divided.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Data Content Accuracy Requirements:
    The expected accuracy of the attributes within this data set is 90%.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

  5. How consistent are the relationships among the observations, including topology?

    This data set is 'historical' information required for some Rangeland processes, today.  Once the data set is standardized, it will become a 'Read-Only' data set.  Any changes/corrections must be approved through the Business Data Steward for Range information.
