Opportunity to get published and share your perspective ...

Metroscope.net research group is inviting images of metros from around
the world.This is a great opportunity to get published since thousands
of images are required for the final publication.
  Fact is that every day two billion three hundred million people take
the metro around the world in 114 cities, spread over 53 countries
speaking 35 languages.
  On top of contributing to an academic publication you will be a
member of the new Guinness world record of photography:the most images
gathered on a single subject.
  Those wishing to contribute images may do so at info@metroscope.net

  Thank you for sharing.Looking forward to doing the same

  Pol Guerin Ph.D for the metroscope.net research group
