At the time that the study started, it was not clear that OpenStreetMap volunteers can create highly detailed maps

This script should be run from the Python consol 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.
