A revolution is taking place in cities across the globe. Tech-savvy individuals are using new technologies to harvest data and create innovative new ways for us to experience the world we live in. In Amsterdam, we meet a pioneering group of digital mappers, hackers and software junkies who are transforming the way visitors can explore their city. These pioneers are breaking new ground, helping to reveal Amsterdam as never seen before, enabling us to travel back in time, experience the smells of the city, be guided by the words of great authors and even create our own museum experience. These exciting maps and apps could change the way we experience other cities across the world.
