Influenza A virus subtype H5N1 few years ago CASA used the Google Maps API to introduce a publish of topographical maps of New York, London, Paris as well as Munich based on where inwards the cities Twitter users are some active. The Interactive Tweetography Maps used contours to map the density of tweets, amongst mountains showing the some active locations on Twitter.
Those maps no longer work. However Digital Urban used the same information from the London Tweetography Map as well as visualized it amongst the 3d game engine Lumion. The results were pretty amazing, every bit you lot tin meet inwards this video of the map.
Now Nick Shelton has created a similarly themed Twitter density map of San Francisco. Using WebGL he has mapped 15,000 Tweets (from January 2015), showing the density of the city's Twitter information every bit a 3d histogram.
SF Tweet Data is an impresive 3d map of the metropolis fifty-fifty without the Twitter histogram. It too includes 3d terrain, neighborhood boundaries as well as population data.
