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.
