This roads dataset for Wyoming has been extracted from the U.S. Census TIGER/Line shapefiles (http://www.census.gov/geo/www/tiger) and is avialable here as a statewide dataset. Data for each county was merged to create the statewide dataset. Road data was then extracted from the 'edges' (attribute: roadflg, 'Y') line data by WyGISC. Attributes deemed unecessary were removed by WyGISC. For the original data, visit the tiger data website listed above. The TIGER/Line Shapefiles are an extract of selected geographic and cartographic information from the Census MAF/TIGER database. The Census MAF/TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each TIGER/Line Shapefile is designed to stand alone as an independent data set or the shapefiles can be combined to cover the whole nation.
