What is a radius map? A definition:

A radius map is created by selecting a point on a map and then drawing a straight line from this point to the circumference of a circle. Within the circumference of the circle, you can see all locations that fall within ‘X miles radius’

The example below shows a 10-mile radius from London city centre. The straight line drawn on the image shows a 10-mile distance as the crow flies.


The map radius tool list

Draw a radius by selecting a maximum distance area
Compare radius to reachable areas by car or public transport
Export postcode data within a ‘travel time radius’ (an isochrone)
Edit the travel time map by transport mode, time of departure and maximum travel time area
