Defence Area Data Fields

Defence area objects are used to represent sea defence structures such as salt marshes, beaches or dunes.

Defence area data can be edited on either the Defence Area Grid Window of the Asset Grid or the Defence Area Property Sheet.

To view and edit all Defence Area data, use the Property Sheet.

The following describes all the data which can be used to define a defence area.
