http://vimeo.com/11540899 Not your fathers approach to geodata creation and sharing posted by moderator Peter Batty. This is quite a long video and I do plan to make a summary of the key points sometime,but for a start there is a very good explanation of openstreetmap as an example of neogeography and powerful pictures from post earth quake Haiti (the building housing the goverment GIS was destroyed in the earthquake so over a matter of days volunteers created new maps from old paper base maps, high res satellite imagery, even Maps from the CIA if I heard correctly – which made a huge difference to the emergency response and saved lives.
Some amusing banter between neogeographers and traditional GIS people cheekily referred to as paleogeographers.
