It seems great that people have now split the tracks into GPS loadable segments. It seems that Jonathan's track isn't reliable though, as it wasn't collected in the field, but drawn on a computer. Why use Jonathan's info over Out of Order's track? Anyone loading either track over the free maps from <a href="http://GPSFileDepot.com">GPSFileDepot.com</a>?

The Google Earth track is just a set of GPS points. You can overlay
them onto any map - either a satellite view in Google earth, or
1:24,000 USGS quads, or 1:100,000 maps, or whatever... I don't know how
Garmin sources their topographic maps, but the resolution will depend
on that, not the track file. <br>
<br>
As for the resolution of the track itself... that depends on how many
points are placed to make up the track. The section in northern MT is a
lot more "fine", the rest of it is rather rough. Also, just keep in
mind again, that this hasn't been updated (at least by me) for some
time, so there will be places where that track doesn't conform to the
actual route on the ground. I just did the .kmz file for "fun" and have
no intentions of keeping it updated regularly. <br>

<div>Let me change my previous rhetorical question to a real one:
Will the uploaded Google Earth map have the same resolution
(information) as the Garmin 1:100,000 TOPO US map or its equivalent?

Just a few comments on this...<br>
<br>
As Blisterfree mentions below, part of the idea was that anyone could
take the .kmz file I created and edit / personalize it. I originally
drew the kmz route about 4 years ago, and had only rudimentary tools at
the time. It involved a lot of exporting, reformatting and importing
data, and a bit of simple .kml coding. <br>
<br>
Now, there is a great kml/kmz editor built right into Google Earth.
Anyone with a computer & the bandwidth (both personal time &
Internet speed) can refine the route, add links to their trailjournal,
add alternate routes, etc. etc. etc... The reason the route is more
refined in northern MT is because I did more work on that section a
couple years ago using the GE editor - drew the route more accurately,
added alternates, added a few placemark notes, and links to photos on
my website). I've had intentions of doing the rest of the route
similarly, but have had too many other priorities. <br>
<br>
Thanks for all the kudos... I have to pass on a lot of that to all the
hikers who send back info each year. The maps stay fresh because of all
the feedback. Right now, I'm searching for the bandwidth to complete
the 2010 updates... as a new homeowner who just spent the past 3 days
painting a ceiling and going completely stir crazy, I'm wondering how
exactly this is going to work... but I'm sure I'll get it figured out
:-)<br>

<blockquote type="cite">Yep, the data is all verbatim from Jonathan's
KMZ file. I'm not sure, but it looks like Jonathan may be adding in
alternate routes from the northern terminus southward. Montana shows a
lot of these, for instance, but few if any south of there, and much of
the "main track" in WY, CO, and NM is presumably templated around what
Jonathan actually walked, ie some of it is surely out of date in terms
of defining a "main" or "most popular" route. Based on his website
description it looks like JL may be accepting "donations" of additional
data, which could be added to his file and then filter downward from
there. <br>
<br>
My main intent with the GPX files was to offer the two (nobo and sobo)
versions of a universally GPS-friendly single-file set of track
segments for the whole trail, that could be uploaded once prior to a
thru-hike and referred to whenever needed, without the need to upload
additional files during the hike due to storage capacity issues. In the
jungle of various GPS data sets available in cyberspace, this seemed to
be a niche that hadn't yet been filled. The compromise with such a
single-file approach will always be the unsatisfactory answer to the
question of which route to offer. My intent is not to answer this, but
if the trail community can settle on something (perhaps the CDTA route
except where unpopular and little-used?) then that might present the
best possible answer for now.<br>

<pre>These posts from Jonathan Ley's maps are great, but note that the
southern terminus for NM is showing as Antelope Wells. This was one of
the two southern terminii when Ley hiked, but now I understand the
"official" terminus is Crazy Cook. I also understand that Antelope
Wells is to be avoided due to drug smuggling and illegal immigration
activity.
