tdoczi, I trend to agree with the statement. I can think of several areas where the wheel would not be accurate. Example, covering the rocks on the trail going from Hump mountain to 19E. Just too rough of a terrain to roll the wheel. I will say this however, my logged gps mileage was within .1 of a mile compared to the listed mileage of the Carvers Gap to 19E section. I believe that the .1 of a mile difference was from when I walked out of the tree line and saw Hump mountain Saturday evening. I promptly turned around and camped at the Bradley gap campsite.
Please disregard my last comment. I just reread the comment in question and am now also confused by it.
There is a difference will be there between the map and actual miles. Map are used mainly for directional signs and simultaneously distance about the area also. A treasure map is drawn to a scale of 2 inches = 3 miles, like-wise different types of maps are available according to the needs and specification areas also. Please produce some more attachments about the topic for view detail information.
That means that wheels can't be trusted to measure anything except for a flat surface, no bumps and no depressions.
The wheel not completely going over (touching) every inch of rocky surface area is a non-issue, since our feet also don't touch every inch of rocky surface area we walk over. And if one were to shoot a laser from point A to B it (the lasar) would not measure all the surface area it passes over, not to mention it wouldn't even measure the zig-zags.

Just keep thinking that and ask the rest of us on the trail what the distance is,and we will give you the correct answer by reading the maps!
Check out the coast line paradox http://en.wikipedia.org/wiki/Coastline_paradox
Basically it says you can't really measure something like a coastline or a trail. The length of the trail will always depend on the length of the ruler you use to measure it. For example we could just draw a straight line from the beginning to the end of the trail, but that would be too short because the trail is wiggly. We could draw a line to the midpoint and from the midpoint to the end and our measurement would get longer. We could continue to break it into quarters, eighth, sixteenths etc. and the trail would always get longer. As the ruler gets smaller and smaller the length of the trail does not converge to any specific length. Now I know a trail isn't a fractal so it won't be infinitely wiggly, but for our purposes the smallest ruler we use is the length of a human pace. Even with the wheel measurements they have to be careful not have it move too serpentine over the trail but have it mimic a human's walking pace or their measurement would be too long.
I work with two wheels to measure houses physical perimeter for termite treatment. As I measure the front vs the back often I am off by 1 foot due to terrain or mulch or some object. Wheels are to get close to the truth, pedometers are USELESS Jokes.
We have had several jobs that have blown up into full arguments with staff over wheel vs Google Earth from practical experience. It has cost me a friendship at work. Everyone wants to be right - just because you think you are right.... doesn't mean you are.
Yea I like this thread.. because it calls out a goofy fact of oops!
There was an Old Man with a owl,
Who continued to bother and howl;
He sat on a rail, And imbibed bitter ale,
Which refreshed that Old Man and his owl. . WOO <Audio
Who cares? Just get out and hike.
I had gone through the post. There is a difference will be there between the map and actual miles. Map are used mainly for directional signs and simultaneously distance about the area also.

the maps are wrong I'm staying home.
its all good
but my compass needle is pointing South instead of North.
its all good
