Many Twitter messages, or “tweets”, are sent with latitude\/longitude information, allowing an insight into the places where the most amount of tweeting happens. For a magazine article, I produced the above map of London, with help from a colleague Steven Gray<\/a>, who collected the data across several weeks using some technologies he has developed. It is a heatmap of sorts, with particular locations where the level of tweets are very high. The data is collected in a 30km radius around central London.<\/p>\n London’s city centre stands out, as would be expected, as well as a distinctive streak of tweets heading directly north – an arm of London where the typical Twitter demographic – young and connected – makes up a particularly high proportion of people living there. Other features – such as along a road in the North West that suffered severe roadworks during the collection period, the A13\/Eurostar travel line running along estuarine Essex, and the runways of Heathrow Airport, also appear. It’s also interesting to see how large parts of surburban London are “empty” of tweets.<\/p>\n
