Eric Fischer at Mapbox has mapped vi billion geo-tagged Twitter messages. The 6 Billion Tweets Map is a nifty visualization of Twitter's global appeal, showing where Twitter is pop as well as also where inward the earth the social network has all the same to attain traction.
Mapping vi billion Tweets is also quite a technical achievement. If you lot are interested inward how Eric was able to handle mapping hence much information on 1 map as well as hence you lot should read his Mapbox weblog post on how he created the map. In detail you lot mightiness locomote interested inward a novel tool which Eric has developed for making vector tiles from large information sets, called Tippecanoe.
For me 1 of the close interesting things that the map reveals is that Twitter can't handgrip Tweets posted along the Prime meridian. H5N1 blank ring runs vertically downward the map along the meridian, hence it looks similar Twitter's geo-location tools can't handgrip Tweets amongst a longitude of 0°.
