I used the AT GIS data provided the Appalachian Trail Conservancy and displayed it on Google Maps.
https://www.google.com/fusiontables/...35&y=2&tmplt=2
I understand there are a few good options already available on the web (including ATC's interactive map). But, every available option uses Google Maps version 2, which is being shutdown in May. Also, I believe this is the first example that uses EVERY data point provided from that very large KMZ file (over 4 mb). You cannot load the KMZ file using Google Maps because it is too large. So, I uncompressed the KMZ to the KML format (about 17 MB), and imported the KML file as a Google Fusion Table. From there, it was rather simple, as Google Drive's Fusion Table editor gave me the ability to load it as a map and create the link which I gave all of you. This should be very efficient, as Google Maps and Google Fusion Table play very nice together.
Have fun playing with it. I find it more efficient to browse the trail in Google Maps than I did in Google Earth.
