Abstract
This line data layer represents state roads for Illinois in 1994. The dataset was originally published by the Illinois Department of Natural Resources in 1994.[These road data are state routes in Illinois. This is a subset of the roads data set stored by county. Note that the functional classification of roadways is the jurisdiction of the Illinois Department of Transportation and is subject to change. Derived from the US Geological Survey 1:100,000 Digital Line Graph files, transportation layer, 1980-1986. Major highways were updated as of 1993. Publication dates of the USGS maps used as sources range from 1980 to 1986. The maximum estimated error in horizontal position based on National Map Accuracy Standards is 167 feet. Attributes include the route number.]
Purpose
This layer is intended for reference and mapping purposes and may be used for basic applications such as viewing, querying, and map output production or to provide a basemap to support graphical overlays and analysis with other spatial data. [In a natural resources context, roads are primarily used as a cartographic element on maps for spatial reference. They are also used for analyses that require, for example, a buffer area between roads and natural features. These data are appropriate for use in local and regional thematic analysis. They are not appropriate as a geodetic or engineering base.]
