The Circle tool is particularly useful for identifying how far a site is from basic social and transport infrastructure. For example, if you are searching sites for a care home then you might have criteria for distances to the train station, hospital, town centre, etc. You can use the Circle tool in any layer.
How to draw a circle:
Open the drawing toolbar and select the Circle tool.
Click and drag from where you want the centre of the circle to be, so that you can measure the radius from it, say, from a train station like this:
If you want to change the radius, you can set it by entering the amounts in the fields on the right-hand side, either as an exact distance, or a rough estimate of time to travel (e.g. five minutes away).
Duplicate the circle by clicking on the three dots in the panel on the right-hand side and selecting Duplicate.
Delete the circle by clicking on the bin icon.
