To manage web map & web feature services (WMS or WFS)

Map backgrounds provide context for your data. Instead of adding your own background images, if the controller is connected to the Internet, you can use an online map provided by a web map service (WMS). Alternatively, you can request geographical features over the Internet using a web feature service (WFS) and then save the data as a .json file so that you can use it in the field without an Internet connection.
