Create a CAP Message

The workflow for creation of a CAP alert is as below.

As the first step of the process, you will need to select a template.

---

A form is displayed to you after the template has been applied on it. You can edit the alert qualifiers now.

---

After you are done and submitted the above form you will be redirected to a page where you can add information about the alert. Fill in the details as it applies

---

After saving the alert information you can click on the "Open" button against the information row to edit it further or to add its components such as Area or Resource.

The next image is slightly obsolete. It shows an embedded "Location" widget (a subform with pick lists, map, and "Draw on Map" button). That's gone now. Instead, alongside the Area tab is a "Location" tab. From that tab, there is an "Add Location" button -- clicking that exposes the location widget. This change allows adding multiple location records to an Area, as the CAP specification allows.

Click on the "Draw on Map" button to open a map to mark the boundary of the affected area.

Some Sahana versions have a toolbar on the map, as shown: its polygon tool will be active by default when you open the map (or select it as needed later).

In any event, successively click then move the mouse, drawing a polygon with vertices at each click. Double-clicking ends the polygon.

Close the map and click on save to commit the area to the alert information.

---

You can now also attach files to the Alert information by going to the "Resources" tab.
