About Route Maps and GPX

What is GPX?

GPX is a standard markup file format for exchanging GPS data. It is widely used for specifying routes followed by hikers, bikers, and vehicles [Wikipedia ].

What can I do with a GPX route map?

There are many apps and software packages for visualizing, analyzing, and creating route maps in this format. For mobile devices, there are apps that will assist you in real time while you follow a GPX-specified route, or record your own track as you go.

The links to GPX route maps on these web pages have the "download" attribute set, which means that when you click or tap on the link, your browser will take the hint that it should download the file. At the same time, the web server will inform your browser that the incoming file is in XML format. Your browser may also offer you the option to open the downloaded file, but opening it will require a GPX-aware app.

A visualization app:

For analysis and visualization of GPX route maps on my desktop or laptop, I've been happy with GPXSee , a free (GPL) software package available for Windows, Mac OS, Linux, and Android. I have it configured to use the high-resolution OpenStreetMap  as the base layer for displaying routes, and I have Firefox configured to "Always ask" when I click on an XML file. This affords me the option to open the file with GPXSee.

Included below is a screen shot of a GPXSee-rendered route map for the Hickory Ridge Trail [see Hike P5].

What about navigation?

For navigation while on the trail or for recording your own tracks, I highly recommend the CoMaps  app, available for iOS and Android. It is free, ad-free, privacy-focused, and works off-line once you have followed the prompts to download the latest OpenStreetMap data for your regions of interest.

With a Chrome browser on Android, opening one of my route maps in CoMaps should work as follows:
