Dataset was developed to generalize the 2000 US Census TIGER/Line Roads layer to a density within 18km of each pixel. Obtained from 2000 US Census TIGER/Line Roads using LINEDENSITY with an 18km search radius. Purpose: Generalize the roads in the western US to indicate density of roads within 18km of each location.
