Description:

Abstract:

Active and abandoned railroads by county at 1:100,000 for all of Illinois and portions of surrounding states. Derived from the US Geological Survey 1:100,000 Digital Line Graph files, transportation layer. Publication dates of the USGS maps used as sources range from 1980 to 1986. Data were recoded to reflect ownership, use by AMTRAK and active/abandoned status as of January 1991. Sidings and yards are included. The maximum estimated error in horizontal position based on National Map Accuracy Standards is 167 feet.

Purpose:

These data are appropriate for use in local and regional thematic analysis involving railroads. All railroads contained in USGS 1:100,000 DLG files are included. These data were corrected and updated as of 1991. Data are not appropriate as a geodetic or engineering base.

Supplemental_Information:

The path to these data sets is *path_name_suppressed*/rails where <county_name> should be replaced with the name of the county of interest. Longer county names have been truncated to eight characters.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

All data were evaluated and compared to Illinois Department of Transportation Railroad Map for Illinois, January 1, 1991.

Logical_Consistency_Report:

Data set is topologically structured linear data with nodes at all intersections. Pseudo nodes (nodes between arcs with common attribute values across all non-system attribute fields) may exist on some arcs.

Completeness_Report:

No statement of completeness was provided with the original USGS DLG data. Visual inspection and use suggests that coverage is comprehensive but reflective of the date of each source map publication date. This date varies across the state.

 COINCIDENT     - DLG feature code indicating the type of feature
                  in other DLG data sets with which this arc is
                  coincident. This attribute was carried over from
