I was recently drawn to the Ordinance Survey’s blog where they had tweeted on image they had received which visualised the postcodes of Great Britain is a rather artistic way. Wondering if this approach was easy to replicate and if other data could be used I had a little play with the DCLG NGA broadband model I’ve used before to see if it was possible to create a short animated sequence which could show the spread of faster broadband.

Click on the image to see it run – it loops back at the end to highlight the gulf between where we’re starting from to where we need to get to.

Its not as polished as the OS image but I think it kind of works. The DCLG data is modelled on the ONS’s super output areas, so I resolved them to postcode level to give more points of light, and the colour simply matches the model’s traffic lights.

At the moment the image only covers England and Wales – Scotland and Northern Ireland have their own statistical output area systems which individually need resolving to postcode level. If I get a quite moment I’ll run additional areas to make the map complete.

      The model was developed by Analysys Mason for the Department of Communities and Local Government and attempts to predict where next generation broadband will develop naturally using a range of sensitivities from 45% deployment to 95%. Each census output area is awarded a traffic light – red, amber, green – assessing whether NGA broadband is probably, possible, or unlikely. The term NGA in this context, I believe, incorporates FttC, FttP and DOCSIS 3. This was produced before the term “superfast” was coined by the minister so it won’t included any of the measures the Department for Business are considering .
