MapBox: What does 6 billion tweets look like?

Sample from Mapbox of Twitter Eric Fisher from Mapbox has been tracking geotagged tweets for 3 and a half years and has produced this incredible map of where in the world twitter activities are coming from:

There are about 10 million public geotagged tweets every day, which is about 120 per second, up from about 3 million a day when I first started watching. The accumulated history adds up to nearly three terabytes of compressed JSON and is growing by four gigabytes a day. And here is what those 6,341,973,478 tweets look like on a map, at any scale you want.

It’s an incredible project and a compelling data visualisation. Eric has written a long blog post about the process he followed to develop it. You can check it out over at the Mapbox blog.
