  Description:

    Abstract: The United States MSA Boundaries data set

      contains the boundaries for metropolitan statistical areas

      in the United States.  The data set contains information

      on location, identification, and size.  The database includes

      metropolitan boundaries within all 50 states.

    Purpose:  The data provide users with information about

      the locations, names, and sizes of MSAs primarily

      for national planning applications.

  Data_Set_Credit:  The United States MSA Boundaries files

    were compiled from a variety of sources including the

    US Bureau of the Census, and data supplied by

    individual States. The data sets were created and

    standardized by members of the Oak Ridge National

    Laboratory.

Data_Quality_Information:

  Attribute_Accuracy:

  Attribute_Accuracy_Report:  Attributes for the MSA

    Boundary database have been created using ARC/INFO, a

    Geographic Information System. All area and distance values

    were 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: Completeness Report Needed

  Positional_Accuracy:

  Horizontal_Positional_Accuracy:

  Horizontal_Positional_Accuracy_Report: The Metropolitan

    Statistical Areas database was compiled from

    TIGER/Line data with a corresponding positional

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

    plus Washington D.C and Hawaii.  TIGER/Line files

    for Puerto Rico and Alaska are at a scale of

    1:125,000.  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 Puerto Rico and Alaska.

  Process_Step:

  Process_Description:  All state supplied maps were

    digitized.  MSA boundaries were added from TIGER

    data and topologically integrated.  The data were

    checked for completeness and accuracy and were

    extracted and reformatted into ASCII data files.

    These were then converted to ESRI shapefiles.

  Process_Step:

  Process_Description: After completing topological and attribute 

    verification using ARC/INFO the data was extracted and

    reformatted into the BTS ACSII format. Which was them

    converted to the ESRI shape file.
