This is really cool. I had an idea recently. I wanted to find a practice area that had the least traffic at lower altitudes (under 10000 feet). If you could generate a heat map like the ones this guy made, but for a longer period of time (a month maybe), you could pretty easily see at a glance where the least amount of traffic is.
Edit: I mean practice areas *away* from the airports!
