Stay on track: Plotting GPS tracks with R
Many GPS devices and apps have the capability to track your current position via GPS. If you go walking, running, cycling, flying or driving, you can take a look at your exact route and your average speed.
Some of these devices or apps also allow you to export your routes in various formats, e.g., the popular XML-based GPX format.
I want to show you my attempts to
- read in a GPX file using R and its XML package,
- calculate distances and speeds between points,
- plot elevation and speed,
- plot a track,
- plot a track on a map.
Here are the results. Everything below the plots shows you how to do it in R. Drop me a comment if you have any questions.
The altitude of the track in time, with smoother. Click to enlarge.
The speed during the run, with smoother. Click to enlarge.
