Introduction: What is the PDF Maps app?

PDF Maps is an award-winning, free map app from Avenza Systems Inc., a company recognized worldwide as a leader in map development software.  The app is currently available on Apple iOS devices (iPhone, iPad, iPod Touch) and is a powerful geospatial PDF reader that allows you to easily download and interact with maps in new and exciting ways.  A map store within the app gives you access to thousands of maps from around the world, from outdoor recreation maps to city transit maps.  This "iTunes for maps" includes free maps as well as maps available for purchase.  The Trail Conference has become a vendor in this map store and has made a selection of trail maps available through the PDF Maps app.

What features are included with the PDF Maps app?

The PDF Maps app includes a number of interactive features that allow you to use our Trail Conference trail maps like never before.  Each map is a geospatial PDF, or a PDF that contains geospatial information such as real world location.  This geospatial information makes it possible to locate specific points and measure distances right on the map.  Here are some of the major features of the app (note that some features require a GPS-enabled device and/or an internet connection):
  • Use simple multi-touch gestures to pan around maps, zoom in/out, add waypoints and more.
  • Use your device's built-in GPS (iPhone and certain iPad models) to see your real-time location on the map.

PDF Maps Tools - PlacemarksAdd waypoints at your current location and even import or export waypoints.


  • Find locations by entering coordinates in a variety of popular coordinate systems.
  • Attach photos to a waypoint.

PDF Maps Tools - MeasureMeasure distances and areas easily and accurately.


  • Navigate with a built-in compass that orients the map based on direction.
  • Access thousands of maps, including USGS topo maps and a growing catalog of Trail Conference maps, directly within the app using the Map Store.
  • Use your maps off-line in areas without any mobile coverage, since the maps download to your device's memory.

What are some specific ways I might use these maps?

Out on the trails, there are many ways you can use the PDF Maps app to enhance your experience.  Here are just a few examples:
  • Plan your route with the 'Measure' tool to make sure you know how long your route will be.
  • Use the 'Compass' tool to orient the map in the right direction so that you can safely proceed on your intended route.
  • View satellite imagery of your location by using the 'Open in Maps' tool (internet connection required).  This brings up the Google Maps imagery found in the Maps app, and this additional imagery may help you navigate to a certain feature.
  • If you aren't quite sure where a parking area is located, use the map with GPS to guide you to the parking area (Caution: do not use the app while driving!  Have a passenger help navigate, or pull off the road to consult the map).  When you arrive at the parking, the GPS location symbol should match up with the parking symbol on the map.Trail Conference Maps on an iPhone
  • If you know the coordinates of a feature you want to find, you can enter the coordinates as a Placemark and see the location on the map.
  • You can view the coordinates of your current position, which can be helpful information to provide to someone that may be looking for you (especially search-and-rescue efforts).
  • Use the 'Find Places' tool to locate nearby points of interest right on the map (internet connection required).  This acts like a Google search right on the map.  Find a nearby campground or hotel accommodations, or find a great nearby restaurant after a long day's hike.
  • You can use the 'Add Placemarks' tool to record locations of features along your route.  You can record a Placemark at a regular interval to keep track of the exact route you have taken.  You can also record a Placemark at features such as a fantastic viewpoint or a waterfall so that, perhaps on a future trip, you can see where those features are located on the map.
  • You can also add photos to a Placemark so that you might later recall where a particular photo was taken.
  • If you use Google Earth or other mapping program on your computer, you can import KML files and export KML/GPX files that include Placemarks.  This allows you to import Placemarks to place on the map, or export Placemarks you recorded on your trip.  The Export function makes sharing of Placemarks easy to accomplish (internet connection required).
  • If you are out on the trail and notice a Trail Problem that the Trail Conference should be aware of, or even a problem with the map itself that should be corrected, record a Placemark and send it along to us with a report of the problem.
