I've always wanted to see how close the trail came to my house.....

This is the entire length of the trail, in line format!
Add the placemark kmz from the parent post, and you've got all the trail data in one map!

Here is the most recently posted polyline file from the AT.org website converted to KML for use in Google Earth.
The GPS data has not been updated for 5 years ( 3/12/02 ), so it might be a bit off, but better than nothing!

The Appalachian Trail website http://www.appalachiantrail.org makes the data available.
I opened it in ArcMap and used an extension released by the City of Portland called Export to KML 2.3.5.
This is a great extension for ESRI ArcMap to export points, lines, and polygons to KML. highly recommended.

Cheers!
and Go Hokies!

The "view in google maps" doesn't work because the KML is too big, FYI.

PS The previous polyline post link was broken, so here's my contribution.
