Visualization: 3 years of GPS-tracked running in the Bay Area
I've been using my Garmin Forerunner running watch for around 4 years now, 3 of which in the Bay Area. Tonight I exported all the data to Google Earth, and was surprised to see the resulting detail that came out of it. It turns out the error in the GPS signal essentially creates a heat map of my favourite runs, which I thought looks pretty cool.
He says on his blog post
that he's going to try to find a way to display the same data with the date and time information display somehow, as well. What I don't understand, though, is where the error in the GPS signal is. This just looks like overlaid routes to me! Tim?
