Six billion geo-tagged tweets have been processed into a map overlay, so we have taken a look at Wrexham via the social media data…
Above is a picture from the map of Eagles Meadow, showing people had tweeted from two defined ends, the left being popular place to grab a shot of St Giles.
The map was created by parsing unique tweets that had location information tagged on them, usually from a mobile phone’s GPS which can be quite scatty and imprecise – but good enough to get a general location picture. Not all tweets are geotagged as often users turn that feature off, similarly some areas simply do not have mobile phone reception so a tweet is not possible.
Below is the view of Wrexham town centre, with hot spots showing at the college, bus station, main shopping streets and supermarkets – specifically the entrance to Tesco. Further out Plas Coch, the hospital and the Racecourse all show quite a light green indicating more tweet frequency:
To the north of Wrexham we have taken two snaps, the first showing the general tweet-spots along the linear path of the A483 plus hot spots at the Beeches and the Pant pubs.
The map shows up the odd hot spot in logical locations, with Chirk McDonalds being one of the brightest green dots to the south of town:
Whereas we were surprised to see the Pontcysyllte aqueduct and area being quite low on usage:
Looking at our near neighbours up the road, Chester’s city centre is green from tourist fuelled tweets, and similar hot spots to us on retail parks, pubs and the like. The station shows as its own cluster to the right.
Each dot is not every single tweet sent due to the lack of geotagging on some, plus processing of the information that has taken place. For example it appears iPhones partially anonymise data opting snapping to linear geodata to avoid revealing people’s exact locations
