The WFS-T service sends a change made to the WFS data back to the source data, ensuring that the same change occurs in the database.

The WFS-T service sends a change (added geometry, deleted geometry, and edited geometry) back to the source data, ensuring that the same change is present in the database. The WFS-T service can be published in the BlueGIS software.

It is easy to add a WFS-T service. There are two ways to access the WFS-T add panel. The first way is the 'Add WFS-T Service' option under the 'Add Map Service' in the left menu.

The second way is the 'Add WFS-T Service' option in the 'Map Services' menu in the quick menu (+ sign) at the bottom of the screen.

Step 2: Send a Change with WFS-T

With the WFS-T service, changes made in layers added to the map (added geometry, deleted geometry, edited geometry) can be sent to the server. If a change is made in the layer (added, deleted, or edited editing geometry), the changes are sent to the service again.

Here, for example, new geometry with a new drawing is added to the layer.

Adding WFS-T Service

It is quite simple to send this added geometry back to the used service. Layers added with the WFS-T feature in the layer box have an additional option called 'send changes'.

Adding WFS-T Service

Clicking this option, all changes made in the layer are sent to the service side. You can see the changes made in the service.

3. WFS-T Service history

There are 3 main menus in the adding WFS-T service panel. There is a 'History' button under the third main menu. In this menu, WFS-T layers added to the map are saved. Thus, a WFS-T layer that is desired to be added before can be easily added to the map without having to re-enter the parameters on the map.

Adding WFS-T Service

The layer we added in the first step is now displayed in history. It is enough to scroll the box to add it back to the map. If desired, easily remove the layer from the history with the "Delete" button.

Adding WFS-T Service

When you activate the button, the WFS-T layer is automatically added to the map again.
