Fresh perspectives from Google Maps
19 April 2005
Search engine Google has added satellite photographs of a range of landmarks and locations in the US and Canada to its popular Maps service.
The integration of Google's Keyhole digital mapping service with Google Maps enables users to enter a postcode and click on new satellite links to convert maps into an aerial satellite view.
Many images have rooftop-level detail and, if satellite imagery is not available, the software will suggest zooming out.
Digital map maker Keyhole Corporation, which was bought by Google last year, provides the satellite maps. Keyhole has data for the whole globe and the service could be rolled out for other countries.
All the popular features of Google Maps are still available in the satellite image mode. Users can still drag the map around with the mouse, the map can still locate and pinpoint businesses in a particular area and users can still get driving directions.
Images now available on Google Maps include the Grand Canyon, Manhattan, Alcatraz and Mount Rushmore. Concerns have been raised about privacy, as the detail on Google Maps is impressive, but Keyhole insists all it photos are at least six months old.
While satellite images have been commercially available for some time, the cost has put the photos out of reach of most individuals.
