Description:

Abstract:

The United States State Boundaries database is a geographic database of state political boundaries integrated with shorelines in the United States containing information on location, identification, and size. The database includes boundaries for all 50 states, the District of Columbia, and Puerto Rico.

Purpose:

The data provide users with information about the locations, names, FIPS Codes, and size of states primarily for national planning applications.

Data_Set_Credit:

The United States State Boundaries files were compiled from a variety of sources including the US Bureau of the Census, National Oceanic and Atmospheric Administration National Ocean Service, and data supplied by State Departments of Transportation. The data sets were created and standardized by members of the Geographic Information Systems Laboratory, Pellissippi Research Institute, The University of Tennessee, Knoxville.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attributes for the State Boundary database have been created using a Geographic Information System. All area and distance calculations are calculated to the nearest 50m.

Logical_Consistency_Report:

All node-link and polygon topological relationships are created and verified using computer algorithms. Uniqueness of entity IDs are similarly verified by computer algorithm.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The positional accuracy of each data set varies as described. The State borders 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_Description:

All state supplied maps were digitized using ARC/INFO V6.1x. All State supplied digital data was converted to ARC/INFO using a variety of encoding methods. The state databases were appended and adjusted to correct minor geodetic problems. State boundaries were added from TIGER/Line data using and topologically integrated using the ARC/INFO GIS. After attributes were added and the data set checked for completeness and accuracy it was extracted from ARC/INFO and reformatted into ASCII data files.

Process_Description:

All state political boundaries were extracted from the TIGER/Line CD-ROMs and appended into a single polygon database using ARC/INFO V6.1x. The NOS vectors were overlaid and topologically integrated into the state polygons using ARC/INFO. After attributes were added and the data set checked for completeness and accuracy it was extracted from ARC/INFO and reformatted into ASCII data files.
