Influenza A virus subtype H5N1 few years ago CASA used the Google Maps API to introduce a lay out of topographical maps of New York, London, Paris in addition to Munich based on where inwards the cities Twitter users are well-nigh active. The Interactive Tweetography Maps used contours to map the density of tweets, amongst mountains showing the well-nigh active locations on Twitter.
Those maps no longer work. However Digital Urban used the same information from the London Tweetography Map in addition to visualized it amongst the 3d game engine Lumion. The results were pretty amazing, every bit yous tin give the axe run across 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 likewise includes 3d terrain, neighborhood boundaries in addition to population data.
