Meta Identifier Roads_100k Type of Data Road statistics Originator U.S. Geological Survey Description These data are from USGS Digital Line Graph transportation linework derived from the DLG-3 digital series at a scale of 1:100000. Road statistics were computed from these data in Arc Info by IFR staff. Data contains several classes of transportation features including jeep trails, city streets, thoroughfares, unpaved roads, state highways, and interstates. Some of the data are 20 years old; therefore, care should be taken when using data from areas that have grown in recent years.
