You have identified a structure (located down stream of the A428 St Neots by-pass bridge)as 'Eynesbury Weir'. In fact it is called 'Eaton Socon Sluice', and on its eastern edge, is Eaton Socon island.

Simon B, unfortunately the answer to all 4 is ... not possible. However, we will add some of these to the Future Ideas list.

Great tool thank you. - How can I save the maps for future use - I'd like to be able to move or remove 1 radius at a time - I want to also see population reach - I would pay to be able to create and share mpas with postcode labels

By qwertyuiop on 5th February 2021

Is there a way to pull the location data? Say I input a postcode and then want to pull all the areas, suburbs, streets etc in the radius? Is that possible?
