# Overlay maps

The same formats (WMS / WMTS / WFS / XYZ) are used in overlay maps. Adding the overlay maps is done exactly the same way as adding background map. The only differences are found when overlay map layer has been added to the project configuration.

Once an overlay map is added, it is listed in the Project configuration. Following actions can be done for the added map layers:

* Edit the name
* Copy the URL of the service
* Change the visualization settings
  * Visibility from 0 to 100, when 0 is fully transparent
  * Ordering where the smallest value is placed in the bottom and the highest on the top
  * Color (only for WFS layers) - allowing to change to color of each WFS layer
* Delete the layer

Map layer can also be deleted from the project, by clicking the trash bin. If there is a need to add more map layer, click **Add a new map** and proceed normally.&#x20;
