Note that the KMZ file available for download with the map on the top of this article is not suitable for hiking but provides only an overview. The accuracy of this KMZ is greatly reduced and this KMZ files does not contain waypoints that are relevant for hiking. Therefore do not use the KMZ file "GPT_Minimized_NOT_FOR_HIKING_AND_PACKRAFTING.kmz" for hiking on the GPT.
==Update of Trail File for GPS and Google Earth created in 2016==
Santiago, December 10, 2016
Dear Hikers,
I extended and updated the Greater Patagonian Trail (GPT). The trail now starts at the last metro station in Santiago and goes all the way to the lake and glacier Viedma south of the Fitz Roy in Argentina. The trail has now a length of approx. 3000 km. I also created new digital maps for handheld GPS devises. These maps can be downloaded from Dropbox using the following link:
https://www.dropbox.com/sh/mbsd9mupzy03zib/AAAF9bRnw-6aW3JZ8cpEGMXva?dl=0
The ZIP file contains the GPT trail network in various file formats. To review the entire trail network on a computer open the KMZ file in Google Earth.
Google Earth File: “GPT Master 20161127.kmz”
This file contains now nearly 12'000 km of tracks and nearly 3000 waypoints.
If you plan to hike the Greater Patagonian Trail you should continue to read carefully to understand how to select, install and use the digital maps on your GPS devise.
If you download and use these maps you do this at your own risk and under your own responsibility. I do not accept any liability and cannot guarantee the correctness and precision of the information provided with these maps. Trails may erode or overgrow, rivers may change substantially with weather and time and poor weather may turn many places along these routes into hazard zones. Therefore do not follow any of these trails blindly. Use constantly your own judgment, plan with contingencies and rather turn back or seek an alternative route if it is not save to follow a track shown on the digital map.
This update contains many improvements and extensions compared with the trail files on wikiexplora that I created and uploaded in 2015. But the general recommendations outlined in this wikiexplora article still apply.
Due to Garmin firmware limitations the Google Earth KMZ file cannot be displayed on a Garmin devise. It is also not possible to upload all this information to a Garmin GPS devise by converting it into GPX files as suggested by Garmin. The number of tracks and waypoints simply exceeds the typical Garmin limits of 200 tracks and 2000 waypoints (only some Garmin GPS models permit up to 5000 waypoints). If you try to upload more items you will get an error message or these items may simply not be displayed on your GPS devise.
Therefore I have created digital maps that contain all the tracks and waypoints. I created in total four maps in the IMG file format. One map contains only the waypoints and the other three maps show the tracks depending on how you plan to travel. These IMG files cannot be displayed in Google Earth.
* Maps with Tracks for Garmin Devises (install at least one of the four IMG maps):
1. Hiking-Only Tracks: “GPT Hiking-Only 20161127.img”.
2. Hiking and Packraft Tracks: “GPT Packraft 20161127.img”
3. Exploration Hiking-Only Tracks: “GPT Exploration Hiking-Only 20161127.img”
4. Exploration Hiking and Packraft Tracks: “GPT Exploration Packraft 20161127.img”
* Map with Waypoints (install this map regardless how you plan travel):
5. All Waypoints: “GPT Points 20161127.img”
These maps are all “transparent” and should be displayed together with a digital topographic map. I do not recommend to use these trail maps without a topographic map in the background.
To install the maps on your Garmin GPS devise simply copy the IMG file into the “Garmin” folder on the Micro-SD card. When starting the GPS devise you may need to enable the map using the map options of your devise to make the map visible. You may install all four maps simultaneously and simply enable and disable the maps as needed on your GPS devise. The map ID numbers were chosen to avoid conflicts between these fife maps (the map ID numbers use the entire range from 16112701 to 16112749).
If you hike without a packraft you should install only the Hiking-Only maps. These maps show all the hiking routes and hiking options but none of the routes on water and none of the trails that lead to these water routes. By using the Hiking-Only map you avoid that you follow unintentionally a trail that leads you to a lake or river from where you cannot continue by food.
If you travel with a Packraft you should install the trail maps that contain also the Packraft options. These Packraft maps contain all Hiking -Only routes plus all Packraft routes. You can also install all four trail maps but enable only one or two maps while traveling (and disable the other two or three maps using the map options of your GPS devise).
The exploration maps show planned routes that are not verified yet. Be aware that these routes might turn out to be impassable or baldy overgrown and you might be forced to return on the same route. In most cases I have pretty good information that these routes were used in the past but in Patagonia it does not take long that such trails get overgrown if not used any more. Therefore venturing on such a trail may indeed become an exploration and you should carry enough supplies since you may advance much slower than expected or you may even need to return on the same route.
The waypoint map displays the approx. 3000 waypoints as small green dots. When you move the mouse indicator onto the waypoint the waypoint name gets displayed showing what this waypoint represents (i.e. a Camp Site, River Crossing or Ford, Water Supply, Trail Diversion …). Only the "Section start and End Points" are displayed differently with the “Trail Head” symbol. I have now added also some "Important Information" points that highlight where to organize boat transfers and trails with restrictions i.e. trails through private natural reserves that should only be used in case of an emergency.
To see constantly the section start and end points and the important information you may install the following GPX file on your GPS devise using Garmin Basecamp: “Section Start and End Points.gpx” and "Important Infromation.gpx".
If you install these GPX files on your GPS you will see a little flag on each section start and end point and the important information points with the section number or the important information constantly displayed (depending on zoom level).
If your GPS model permits up to 5000 waypoints you may in addition install the following GPX file on your GPS devise using Garmin Basecamp: “Way and Decision Points.gpx”
If you install this GPX file on your GPS you will see a little flag on each waypoint with the name constantly displayed (depending on zoom level). This facilitates anticipating what lies ahead of you but this will works only on specific GPS model (check the Garmin web page to find the limits of your devise).
I’m not sure if the GPX files can simply be copied to the GPS Micro-SD card. At least on my devise it did not work when copying the GPX file to the same location as the IMG file. Therefore I installed the GPX file(s) from my computer using the Garmin Basecamp software.
Note that I did not had the time to harmonize the nomenclature of the tracks and waypoints so the naming of these items is not particular consistent and conclusive. Therefore simply ignore if a track has i.e. the name “Untitled Path174” and focus on how the track is displayed (line color, line width, continuous or dotted).
'''Changed Digital Map Nomenclature'''
* Line color: I have selected a few line colors that provide a good contrast on the GPS screen and that can be easily distinguished from each other and map features i.e. roads.
* Black: All Hiking Routes on land are now in black regardless if they are part of the Hiking-Only trail network or if they lead to a packraft water track. Therefore it is essential to install and enable the appropriate map. I changed it from red to black since this black provides the best contrast on all map features i.e. on roads.
* White: All Ferry Routes or private boat transfer tracks are in white (good contrast on the blue water background).
* Red: All Packraft Routes on water are in red (good contrast on the blue water background).
* Violet (Dark Pink): All Exploration Hiking Routes on land are in violet. Be aware that these routes might turn out to be impassable or baldy overgrown and you might be forced to return on the same route.
* Pink (Light Pink or Magenta): All Exploration Packraft Routes on water are in pink. Be aware that these Exploration Packraft Routes may cross very challenging lakes, rivers and fjords where i.e. wind may force you to wait several days for better weather. When you get on such a route carry enough supplies and check the weather and wind forecast regularly i.e. using your Delorme InReach satellite messenger.
* Line width: All tracks are either 2 or 4 dots wide providing a good contrast to the 1 dot wide altitude lines.
* Thick: Regular Routes are the normally recommended tracks avoiding particular difficult passages but avoiding also hiking on roads. The Regular Routes is the to my opinion the best compromise between beauty and difficulty.
* Thin: Other Routes may be side trips, climbs to summits, short cuts, nearby roads and alternative entry and exit routes. I included in the route network many roads and trails in parallel to Packraft Routes to indicate possible “Escape Routes” if you can’t continue paddling on water. So some Other Routes might be more scenic (and difficult) compared to the Regular Route while others are not particular attractive and serve mainly to leave a certain area.
* Continuous, dotted and arrow lines: To minimize the number of colors needed I opted to use lines that are either continuous or dotted or consists of arrows.
* Continuous line: Reasonable reliable tracks that are either based on a GPS records or a trails that are reasonable good visible on satellite images.
* Dotted line: Investigation track for which I either do not have a good GPS record or no conclusive satellite image to clearly see the trail. In most cases I have relative reliable information that this trail exists and was hiked recently but the precise location of the trail is not verified. Expect some discrepancy between the actual trail to the dotted line on your GPS and rather follow the visible trail than trying to follow the dotted line on your GPS.
I now added Arrow lines: Packraft routes on water that can only be taken in one direction i.e. rivers in flow direction or large lakes in the predominant wind direction are shown as a line of arrows.
If you use these maps I ask you for three favors in turn.
1. I tested these maps only on my Garmin devise (GPSMap 62st) but not on other models. Please provide me a feedback how the installation and display of these digital maps worked on your GPS devise.
2. If you use these maps for hiking please record by GPS your entire hike and provide me all GPS records afterwards. This is essential to maintain, update and improve the GPT trail documentation.
3. Please record and share with me additional waypoints that you consider relevant and provide updates to existing waypoints in particular if changes occurred.
I plan to send a new update later in 2017 after this hiking season. In case you do not wish more updates in the future please advise me by email.
Enjoy hiking and take care to not hurt yourself nor the land on which you are hiking. Leave no trace and be a pleasant guest when meeting people on the trail.
Best regards,
Jan
