Nashville tweets and photos are pretty!
He wrote that ‘the data from North America is pretty surprising! Twitter use is heaviest on in the Southeast and Eastern Seaboard, with much less action on the typically tech-heavy west coast. The central states are, unsurprisingly, something of a dead zone.’
I reached out to Eric to see if it would be possible to please create one for Nashville, and he did. Thanks Eric.
Nashville isn’t exactly a dead zone, but I’ll agree that it’s not quite as impressive as bigger cities with much larger populations. Still, I think the Nashville visualization is pretty cool.
Eric mentioned that this should be even better once he’s had more time to collect additional Twitter data. I’ll update this post when there is an updated image.
The red dots are locations of Flickr pictures. Blue dots are locations of Twitter tweets. White dots are locations that have been posted to both.
I found this additional information on the DailyMail:
- it takes 40 minutes to set up file data and 3 minutes to produce each image.
- the programme ‘runs through the photos/tweets in chronological order, plotting the earliest ones the most brightly and stepping the brightness down for points that don’t show up for the first time until later on.
- ‘Points are also allowed to diffuse by a few pixels when there is an additional record for a point that is already plotted, with the brightness falling off exponentially as the point that is actually plotted gets further from its intended location.
- ‘Each pixel is the somewhat weird area of 2.25 square miles because a smaller area made the whole-world image too big for Flickr to let me post it.
