  1. Add your base map

    (If you do not have any basemaps yet, follow along here)

In the browser, select XYZ Tiles. Then select your desired base map, (we use OpenStreetMap a lot, but feel free to try a few out!).

Add base maps to QGIS

Go to Plug-ins>Python Console. Paste the below script into the console and run.

    """
    This script should be run from the Python console inside QGIS.

    It adds online sources to the QGIS Browser.
    Each source should contain a list with the folowing items (string type):
    [sourcetype, title, authconfig, password, referer, url, username, zmax, zmin]

    You can add or remove sources from the sources section of the code.

    Script by Klas Karlsson
