Title: Snake/Salt River Basin Plan - County Boundaries

Abstract:

This dataset contains information on the county boundaries and names for Wyoming mapped at a 1:100,000 scale.

Supplemental_Information:

The dataset's original extent, coordinate system, and data format have been altered. The dataset has been clipped to the extents of the Snake/Salt 6th level hydrologic unit code watershed boundaries. The coordinate system has been changed to Lat/Long NAD 1927, and the data format has been converted from an ESRI coverage to an ESRI shapefile. These data alterations occurred in 2003 for use in the Wyoming Water Development Commission's Snake/Salt River Basin Plan.

3. What does it look like?

4. Does the data set describe conditions during a particular time period?

   Calendar_Date: 1993

   Currentness_Reference: date boundaries were digitized

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 (79)
      • String (428)
      • GT-polygon composed of chains (24)

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

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.

   Hours_of_Service: Monday through Friday, 8 a.m. to 5 p.m., Mountain Standard Time

This dataset was developed for the purpose of displaying 1:100,000-scale counties, also it has been used for clipping other data layers to specific counties.

1. From what previous works were the data drawn?

   BLM maps (source 1 of 1)

   Bureau of Land Management, 1974-1991, BLM Surface Management Status Maps.

   Type_of_Source_Media: paper maps

   Source_Scale_Denominator: 100000

   Source_Contribution: source of county boundary information for Wyoming

2. How were the data generated, processed, and modified?

   Date: 1993 (process 1 of 4)

   The coverage was digitized from the BLM maps and edgematched into full statewide coverage. The state boundary was also digitized and edgematched in the same manner concurrently.

   Date: 2003 (process 2 of 4)

   The dataset's original extent, coordinate system, and data format have been altered. The dataset has been clipped to the extents of the Snake/Salt 6th level hydrologic unit code watershed boundaries. The coordinate system has been changed to Lat/Long NAD 1927. These data alterations occurred in the 2003 for use in the Wyoming Water Development Commission's Snake/Salt Water Basin Plan.

3. What similar or related data should the user be aware of?

1. How well have the observations been checked?

   Only one attribute, county names.

2. How accurate are the geographic locations?

   The Surface Mangement Status Maps from which the counties were digitized have an accuracy of +/- 120 feet, according to USGS national mapping standards. Because some of the digitization was from folded or otherwise poor quality paper maps, there is a 5-8% range of error associated with this digital data, translating to approximately +/- 300 feet.

3. How accurate are the heights or depths?

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

   All attributing is complete.

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

   All polygons are closed and adjacent polygons do not have identical attributes. Each polygon has one label.

Are there legal restrictions on access or use of the data?

Access_Constraints: none

Use_Constraints:

This dataset was produced with an intened application at the 1:100,000 (or smaller) scale. The dataset was created specifically for use in the Snake/Salt River Basin Plan Project as a guide to 1:100,000 USGS quadrangle boundaries.
