An Australian Ph.D. student from the University of New South Wales named Robbi Bishop-Taylor is the one who has redrawn Europe by mapping out its waterways. Bishop-Taylor was able to do this using open source geographic informational software called QGIS to research the 1.35 million streams throughout Europe. The result is a map of European with various blue colors and lines to dictate the different waterways. The thickness of the lines represents the number of each river’s tributaries.
