Deleting Layers

Discard an unused Layer​

You can delete any Layer that you've created from a data source. Deleting the Layer will not delete the data source itself. Be aware, this change will affect all users in your Horizons project, and you may not have permission to delete some Layers. You can delete Works Plans and Treatment Set Layers but not Survey Layers or Network Layers.

Caution

Once a Layer has been deleted, the process cannot be undone!

Check Layer usage​

An error message will be displayed if you attempt to delete a Layer currently in use by the Analysis module. You can check where a Layer is used.

Priority​

When creating or editing a Priority, you can hover over a row to display a tooltip with the name of the corresponding Layer. These cannot be deleted while in use by the Priority.
