The Appalachian Trail (A.T.) interactive map, built cooperatively by the Appalachian Trail Conservancy (ATC) and National Park Service using ERSI's Arc GIS Online mapping technology. While useful, this map is for general reference purposes only and not intended to replace the more comprehensive and accurate A.T. printed hiking maps, available from the Ultimate Appalachian Trail Store.

gis data

Our GIS data sets were developed to provide a digital depiction of the Appalachian National Scenic Trail centerline and several of its trail features in an usable and easily transferable format to assist the A.T. staff, agency partners, and trail-maintaining clubs with land-management duties; to aid local planning agencies, telecommunications companies, and other groups with planning activities, such as siting telecommunication towers or other new developments that could have a substantial impact on the Appalachian Trail; and for scientific and educational use by universities and other groups.
