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
around the world take the metro, in 114 cities, spread over 53
countries speaking 35 languages.
  On top of contributing to a academic publication you will be a
member of the new Guinness world record of photography:the most images
gathered of a single subject.
  Those interested in contributing 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
