Mapping and Geographic Information Systems
Accurate maps are essential tools for anyone who walks or works on the Appalachian Trail. The Trail is constantly changing: new land is acquired, shelters are added, access points are closed. ATC uses geographic information system (GIS) and global positioning system (GPS) technologies to:
- Store information for the 250,000 acres of public land associated with the A.T.
- Produce maps for publications and presentations.
- Analyze the potential impact of towers, highways, and powerlines.
- Identify threatened areas to help focus protection efforts.
|
- Map Trail resources, from shelters to wetlands to endangered species.
- Conduct Trail assessments and collect data for environmental assessments.
- Design future Trail routes, camping sites, and other features.
- Calculate acreage for agricultural fields and other managed areas.
