This is amazing. I wonder if mine would show anything other than a large dot at home and a large dot at work.
Wow! This is cool! You can certainly see the heaviest dots around UT. It seems like I can tell you're a UT student (of course, that's obvious from the username) who most likely owns a car (judging by the highway dots), likes concerts (judging by the heavy red river dots), and lives and commutes near the north most part of the 653 bus route.
On second thought, it might be creepy knowing that if people had access to this data, they could figure all this out without ever meeting you...
It is not really a heat map, there is no change in color or opacity depending on the amount of visits to each point in the map. It is basically just one long location track.
Awesome use of that data there! First and only think I can think of though... is how everyone’s cell phone provider has this exact same thing and more... for each and every one of us.
