Hello,
I have just created an elevation profile for the AT, which I think some of you will find interesting. It's a continuous, unbroken profile for the entire AT, with about 500 placemarks. However, you'll need to read the notes below before downloading:
Notes:
1. The file is in PDF format, but it doesn't seem to work with the normal "Acrobat Reader" which everyone has on their computer. The reason is because the dimensions of the profile are so outrageous (4 inches X 41 feet). So the only way I know to view the file is with the Foxit Reader, which is a free download. It's basically the same as the acrobat reader... but without the size limitation.
2. If you try to view the pdf with your browser it probably wont work due to the size limitation mentioned above, so you'll need to save it to your computer and view it with Foxit.
3. Here's a link to the file: LINK, it's about 2.5 MB.
