Air networks of 18,756 flights are from ICAO statistics provided by Andy Tatem of Oxford University.
Global paved and unpaved roads come from ESRI's Digital Chart of the World.
Shipping lanes data were taken from NOAA's SEAS BBXX database, between 14.10.2004 and 15.10.2005.
Urban areas are from www.naturalearthdata.com -- thank you so much for this amazing site.
Comments and critics welcomed!
