The way we interact with our actual surroundings and the semantics of the way this is represented has been in constant evolution. Remember the flat world and the fear to fall ot it? Maps in all sort (navigation routes, copernican views, mercator view,...) have represented our surroundings, often being kept as military or commercial secret. The advent of cheap processors and affordable internet bandwith brings about a new interaction of citizens on their surroundings. This blog is about the GEO 2.0 evolution.
