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, the District of Columbia, and Puerto Rico.
Purpose:
The data provide users with information about the locations, names, and sizes of MSAs primarily for national planning applications.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes for the MSA Boundary database have been created using ARC/INFO, a Geographic Information System (GIS). All area and distance values were calculated to the nearest 50m.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: unknown
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: Not Available.
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.
