This data layer includes the internal boundaries for the United States and the political boundaries of the US, Canada and Mexico. The state boundaries are drawn to the US coastline and does not include any coastline or islands. This data layer may be used with the high resolution NOS80K coastline (allus80k.shp) which does not include any internal boundaries.

This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.
The origin of this dataset is compiled from ESRI's 50 individual state 'trct' files. Please view the Source Information for more details

This dataset was created to be used with the NOS80K coastline (allus80k.shp) to provide state bounds without redrawing the coastline. In creating the data layer, some issues of the NOS80K coastline became apparent. One example, is the US/Mexico boundary. The NOS80K coastline closes and draws a straight line well below the Texas border. The same type of problem can be seen around the US/Canada boundary of the Great Lakes. The state_bounds.shp will draw the political boundaries while the allus80k.shp file will display the US beyond the political boundaries. If this is unacceptable to the user, they should consider masking the annexed US possession.
