This feature class contains centerline data for trails in the state of Pennsylvania, as prepared by the Pennsylvania Department of Conservation and Natural Resources, Rails-to-Trails Conservancy, PA Fish and Boat Commission, and the Keystone Trails Association. The majority of the data was collected using GPS units and checked for quality and accuracy against high-resolution aerial imagery. See Method. GPS data was collected between November 2007 and October 2009. Trail updates are submitted by users through explorepatrails.com and are evaluated and updated on a regular basis. |
