Frequently-anticipated questions:


What does this data set describe?

    Title: Snake/Salt River Basin Plan - Transportation
    Abstract:
    Transportation for Wyoming, including interstates, state and county highways, neighborhood and connecting roads, jeep trails, and other road and trail types, developed by the US Census at 1:100,000-scale. The Wyoming Water Resources Lab has tiled this information together by 1:100,000 quadrangles for Wyoming and created an attribute table which contains a description of the primary road/trail attribute, CFCC. A subset of this dataset is also available, including only federal and state highways for simplified display purposes. In order to reduce the size of this subset, the line segments were dissolved to remove unecessary segments. The data is available (both statewide and tiles) in ARC/INFO export file format and in ArcView shapefile format.

    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):

      • String (5002)

    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.

    Entity_and_Attribute_Overview:
    There are two items of interest in the arc attribute table. CFCC contains a detailed coding scheme for roads and trails. Explanation for these codes can be found in the accompanying INFO file, tigerroad.class (the same information is also in roadclass.dbf for ArcView users). The item ROADCLASS is a reclassification of the CFCC attributes into a less complex scheme with only 5 values: 10 (interstate), 20 (state highway), 30 (connecting or county roads), 40 (neighborhood roads), and 50 (jeep trails).
    Entity_and_Attribute_Detail_Citation: none
