Zoom to an area of interest
Using the navigation tools, zoom to your area of interest.
You may wish to add the current permit layer you are interested in to give a reference point (eg. ML Permit Granted, or EPC Granted).
Note the Permits Over Time tool at the bottom right of screen. Activation of the tool is scale-dependent, so if it is greyed out, zoom in until it becomes active.
Once it is active, click on the tool to open the timeline.
The timeline then opens. Select your feature type from the drop list. ML in this example.
