A while ago I played around with GPX files and uploading them to a Google Fusion table. You can upload them to google maps (the best method for smaller files) but the file can only be a few miles long which is really, really annoying.
I discovered fusion tables was the way to go but it’s quite a complicated process.
Given that there’s been wildfires on the Great Divide Trail, and I will probably have to find another route, recording a trail might be useful. It won’t be available for this years hikers (because I’ll have to do the hike, then edit the file when I get home) but it might be useful for future hikers! I will try write down a little note about supplies in the area or that kind of thing. Fusion tables lets you add a lot actually, so I guess I could add it to the map, possibly (it’s reallllllllllllllllllllllllllly boring to do though, lol).
Some people suggest bounce boxes or mailing your supplies, but given that I’m from England, it’s a lot, lot more difficult. I can’t promise I will make extremely useful notes because I want to enjoy the hike and in my free time I want to take photographs, but if there’s anything you want me to make a note of, let me know and I’ll try.
