CHATTANOOGA (WRCB) – Tennessee is turning to modern technology to trace the state's history.

On Wednesday the Tennessee Department of State announced an interactive map of events during the Civil War, using the state's geographic information system or GIS.

The first of its kind in the nation, the Tennessee Civil War Geographic Information System (GIS) Survey shows hundreds of locations where Civil War battles, engagements, skirmishes and other military actions took place.

The interactive GIS application for the Civil War in Tennessee is now available at:

The web site allows modern aerial photography, street maps and land use maps to be overlaid onto sites where Civil War actions occurred in Tennessee. It also links narrative information about these events from the Tennessee Civil War Sourcebook.

Complete accounts of all the state units that served in the war are searchable by county along with 1860 United States Census data.

"Learning about the Civil War is fundamental to understanding Tennessee history," said Secretary of State Tre Hargett. "By linking information from the State Library and Archives with maps, Tennesseans can tour battlefields across the state without leaving their homes."

Other TSLA materials used in the project include original documents, photos, historic maps and military unit histories by county of origin. The Tennessee Civil War GIS Survey builds on efforts of the Tennessee Civil War Preservation Association and the Tennessee Civil War National Heritage Area.

The Tennessee Civil War GIS Survey is a project of the Tennessee State Library and Archives (TSLA) and is funded by the American Battlefield Protection Program (ABPP) of the National Park Service. TSLA is a division of the Office of the Secretary of State.
