Apparently Google’s satellite map imagery was used by the recently arrested alleged terrorists in planning their attack on New York’s JFK. This is one example of where increased access to information can have a downside, but for the most part the stories coming out of Google’s amazing map service are positive. Aid groups are using satellite imagery to watch attacks on villages in Darfur, an Italian programmer found archaeological remains based on a strange shaped shadow and Iraqis can use the service to draw up maps to escape from local militant groups – or ‘liberating’ troups.
