Editing a Polygon Zone

1. Edit the name, colour, fill type and zone type as desired.

Note: When editing the name of a source zone, you will be asked if you want to update all the measurement source data attributed to this source (see below). This only matters when there is measurement data associated with this source zone.

If you click Continue Without Updating, those measurements will be orphaned from the zone.
You cannot calculate the odour footprint of this source without a source zone.
