In 2014 I thru-hiked the Appalachian Trail northbound from Georgia to Maine. My progress can be viewed on the map below.
About this map
The map on this page is rendered by Mapbox from this repository. The GeoJSON is generated using Check In for Android and a custom server. New data is pushed to the Git repo on an hourly basis by a cron job, though in reality there will only be new data about once per day (or whenever I reach a town with Wifi to upload it). More information about my 2014 attempt to thru-hike the Appalachian Trail can be found in these posts.
