Mapping ancient Rome with Google Street View

Google's Street View programme, which takes photographs of public roads and puts them online as a navigation tool, has an ambitious new project - to capture the archaeological sites of Rome.
A team has already photographed the Colosseum with its hi-tech camera system and is now working on the Roman Forum.
The Street View scheme has been banned by some countries because of fears about privacy, but Google says it has put in new safeguards.
