I have been fascinated by the bio mapping project by Christian Nold for a few years now. The idea of combining a GPS with a lie-detector in order to “measure” the emotions associated to places is really appealing. So I was quite intrigued by the “Emotional Cartography” book that has just came out of this project. This book is downloadable for free which is definitely an asset. What is even better is that it provides different critical perspectives on this project and more generally on the overall development of the relationships between geospatial technologies, the body, the emotions, the private sector and the State. Among the different pieces, I really enjoyed “A Future love story” by Marcel Van Der Drift: stimulating, entertaining and frightening. Overall, I had a very good time reading this book, even if I would have liked more concrete examples of the use of the bio mapping tool in different contexts; may be in the next volume.
