Attendees will learn about the work of the all-volunteer Potomac Appalachian Trail Club (PATC) GIS Committee. The trail map program began in the early 20th century as a paper and pencil survey of “distance and direction,” measured with a compass and pacing or a measuring wheel. Today, trail maps begin with data collection by the Club’s GPS Rangers. The GIS Committee edits the trails, manages the club’s trail data and distributes trail maps in print, online, and via mobile apps. Going into the future, we are looking to meet hikers’ needs by offering our reliable trail data in new ways.
