The wealth of metadata that comes from millions of Tweets can be used in countless different ways. Eric Fischer and MapBox used the data from 280 million tweets to create some amazing visualisations for Gnip that highlights tourist activity in different cities.
Dating back to 2011, the data was pruned to remove multiple tweets from the same geographic location, emphasizing geographic distribution rather than other factors such as frequency. Gnip and MapBox only selected tweets with location metadata attached, ranging from 2% to 4% of the total tweets in Twitter’s stream of data – known as firehose.
