While Google's UK Maps service is far from incomplete, it's not easy to comprehensively cover a vast array of British towns and countryside without a bit of local knowledge. Hopefully, that's exactly what we'll get with the launch of Google Map Maker in the United Kingdom, including the Isle of Man, Jersey and Guernsey.
The idea behind Map Maker is that local residents can contribute to Google's existing maps, and when any additions or edits have been approved, they will become available on Google Maps and Google Earth. The difference that this can make to local areas and attractions is clearly quite significant, as you can see on the before and after shot of Bletchley Park, in Milton Keynes.
If you want to begin mapping out local places yourself, you can head over to google.com/mapmaker to get started.
