You can edit all the details of your areas using the Edit button next to the area on the My Areas tab.
If you drew on the map, you will be able to easily edit the details and the area itself.
Unfortunately, if you try to edit this information for an area that has been based on a standard area, you will be asked to choose the area again from the list. We aim to amend this soon, but for the time being we recommend you take care with your names and descriptions to reduce the need for editing, and record the steps taken to define the standard area in case you need to do it again.
Please note: Any changes which you make to how the area is defined will not affect previously generated reports. Therefore you will need to generate a new report for this area if you would like the data within the report to match the new area specification.
