[Cdt-l] Gaia GPS app in place of dedicated GPS unit

Yes, the tracks on the apps are followable.  I also have been programming GPS units and SD cards for a few hikers this year which include tracks.  The tracks are a bit diluted to make them manageable, but better than anything else available. We are using some software that removes points in straight places but keeps them on the corners and the results are fairly good.  A Etrex 20 will internally hold tracks for the entire CDT as well as all the waypoints in POI format.  (Those POI files are available on the website for free download.) That leaves the SD card slot free to load map cards which is as good a setup for a Garmin that I am aware of.

> The dedicated CDT apps look great. I see that these appear to incorporate tracks along with the Bearcreek waypoints. If that's correct, then are the tracks followable within the app? Are these tracks (presumably just of the official route) available elsewhere for use in third party apps, GPS units, Google Earth API's etc?

>> Although a dedicated GPS unit like the eTrex 20 / 30 will provide slightly better accuracy, another approach is to use a smartphone GPS app such as Gaia GPS. This app is considerably more intuitive to use than the eTrex series, has essentially no storage limits beyond those of the device itself so you can load all the Bearcreek waypoints without having to convert them to POI's, and you can view and query all of the waypoints without jumping through hoops. Because you're only planning to get a fix on a waypoint here or there for guidance purposes, rather than following a GPS track all day, 3 meter accuracy and a full week of battery life are less crucial. 
>> Off-contract Samsung Galaxy phones running Android can be had for less than half the price of an eTrex 30. I've only used the iPhone, GPS functionality is independent of a cell signal using Gaia GPS, but would assume the Galaxy mimics the same functionality. Accuracy is fine for casual use, might take a bit longer to handshake on startup without a cell signal / sim card installed.
>> Battery life can be extended with an external USB battery charger, such as Anker Astro, which comes in various capacities that work out to about 1-2 ounces product weight per single recharge capability.
>> Gaia GPS app installation and upload / download management would be via a WiFi connection in the case of a phone without a cell signal or sim card. Gaia GPS can store 1:24000 quad maps for off-line use, possibly not for the entire CDT at once though, given the very large size of that data set. But probably enough maps could be stored strategically to reach the next known WiFi connection in town.
>> The eTrex 20 is my go-to unit for field-recording tracks and waypoints, where accuracy and battery life are the most crucial. But were I to thru-hike the CDT with Bearcreek's data, I'd probably just carry my cell phone and save on the extra weight and fiddle factor. Ultimately GPS doesn't normally factor into one's hiking day to the extent that one might imagine it would.
