Are the 2007, 2008, and 2009 Road Network Files consistent with other Census products?
The 2007, 2008, and 2009 Road Network Files are a geographic reference product made available to users who wish to have an annually updated road network file. The 2007, 2008, and 2009 Road Network Files are not compatible with 2006 Census Geography products. It does not replace the 2006 Road Network File, which is a similar product available as part of the 2006 suite of Geography products, and used in conjunction with products and services from the 2006 Census.
