Mapumental
Came across the Mapumental service recently. Mapumental comes out of mySociety and the basic rationale is to take public transport timetables, link them to underlyingOS postcode data and then display isochrons using Leaflet with underlying OpenStreetMap data. See their About page for more details.
The interface is beautifully simple - feed in a postcode, set the time isochron to display and then let it do its stuff. An obvious application would be: for a job at X, where can I live?
Let’s say you want to work at Kingston University (no better place!) and are prepared to travel 90 minutes by train, what are potential places to live? Well not surprisingly pretty much all of London, but there are some surprises. Milton Keynes and Brighton being the most far flung. But also Winchester, Tonbridge, Luton, Chelmsford.
Great resource!
