      IntroductionThe Appalachian Trail is maintained by individual clubs composed
	almost entirely of volunteers. Part of the trail maintenance 
	involves the placement or relocation of trails and shelters.
 
	While there are very powerful GIS programs, their cost and
	licensing do not always match with volunteer efforts.  This project
	allows building of reasonable quality maps based on open-source
	resources. Clubs can generate and freely distribute maps without
	licensing restrictions.
      SamplesHere are some examples of the data and maps.
ResourcesThe project to produce these and other trail maps is based on the following resources:
