Beyond Dots on a Map: Visualizing 3 Billion Tweets

#sxsw #socialgeo

Iap24794

What can 3 billion geotagged Tweets collected over 18 months tell us about the world?

We mapped this huge data set, taking a look at Twitter's userbase in incredible detail – revealing demographic, cultural, and social patterns down to city level, across the world. This is a story about working with 3 billion Tweets, and a search for patterns in a big set of data that evolved over time.

As we began working with the data, stories emerged on the map – road networks around the world lit up, we discovered where tourists go vs. where locals hang out, saw gentrification boundaries reflected in Tweets from Android vs. iOS, and uncovered the complex patterns of languages spoken within and across countries.

In this session we'll walk through the maps and talk about the stories in data. We'll also talk about lessons learned and how to work with geodata at this scale. We'll end with a vision of what we can expect to learn as geodata evolves as a critical component of all social data.
