Earlier today I read Nathan Yau’s post that had a quick R script to plot GPX file data onto a map. I was able to quickly load up my RunKeeper data from 2013 and came up with a pretty cool visualization of each of my outdoor runs. Since my runs occurred across multiple cities and continents the visualization turned out to be very sparse without a great sense of where the runs were. I made a two quick changes to the script to make it more useful for my data: a map overlay to see where in the world I ran and an ability to view a zoomed in area of the map. I’ve included the updated script and the resulting plots below.
A few specks here and there - clearly visible runs in the NY/NJ area as well as some in Virginia, New Orleans, and San Francisco. Can also see a few runs in India.
Zoom in on my runs in the Hoboken/NYC area. I don't have the lat/long coordinates here but if I had them it would be pretty easy to generate a map overlay.
