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 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. en 200509 publication date Complete None planned -80.845015 -67.158958 47.415129 38.607004 -80.845015-67.15895838.60700447.415129 General U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP Woods Hole Science Center Geographic Information System GIS ArcView shapefile polyline state bounds us and Canada boundary internal boundaries OFR 2005-1018 Open-File Report 2005-1018 General North America United States US US Atlantic East Coast northeast New England Long Island Sound None None Valerie Paskevich U.S. Geological Survey Information Specialist, GIS Coordinator mailing and physical address

This data set contains a subset of the internal boundaries for the continental US and the US/Canada and US/Mexico political boundaries. Valerie Paskevich Unpublished Material 1.0 vector digital data disc usa.shp The compiled usa.shp file was used as the source for this new data layer. The usa.shp file was copied and editted to remove the coastline and islands. Because the file contained shapes for the individual states, duplicate common boundaries were numerous. The file was edited further to remove these duplicate shapes and remove the original table information. A final clean-up was done to combine (UNION) line segments and reduce the number of individual shapes. usa.shp 20021003 1440 state_bounds.shp Valerie Paskevich U.S. Geological Survey Computer Specialist mailing and physical address
