  Description:

    Abstract:

      The Bureau of Economic Analysis (BEA)database is a Geographic polygon data

set representing county based economic regions for the United States.

 

    Purpose:

      The database provides locational information for

      use in national and regional cartographic and spatial

      analysis applications.

  Data_Set_Credit:

    The data set was compiled by the Bureau of Transportation

    Statistics from the NTAD county database.

 

Data_Quality_Information:

  Attribute_Accuracy:

    Attribute_Accuracy_Report:

      Attributes for the Bureau of

      Economic Areas data set have been created using ARC/INFO,

      a Geographic Information System. All area and distance

      values are calculated to the nearest 50m.

 

  Logical_Consistency_Report:

    All node-link and polygon topological relationships

    are created and verified using ARC/INFO.  Unique entity

    identifiers were similarly verified using ARC/INFO.

 

  Completeness_Report:

 

  Positional_Accuracy:

    Horizontal_Positional_Accuracy:

      Horizontal_Positional_Accuracy_Report:

        The positional accuracy of each data set varies

        as described. The County borders database was compiled

        from TIGER/Line data with a corresponding positional

        accuracy of +/- 80m for the contiguous 48 States

        plus Washington DC and Hawaii.  TIGER lines for

        Alaska are at a scale of 1:250,000.  The shorelines

        for the 23 coastal states were created using 1:250,000

        NOS digital data which has a positional accuracy of

        +/- 200m.  Thus, all internal political boundaries

        have a higher accuracy than do the coastal definitions

        with the exception of Alaska.

    Process_Step:

      Process_Description:

        The Bureau of Economic Analysis (BEA)Economic Areas was

        created using the NTAD county data set and a list of the

        redefined economic areas from the BEA. The data was

        compiled using ARC/INFO. After completing topological

        and attribute verification using ARC/INFO. It was then converted into a

  shapefile format. (Adjoining counties which comprise the BEA regions

        were merged into unique polygons.)
