Google's Maps Street View service pilots indoor photos

Google has started a pilot project allowing the public to look inside shops and other businesses found on its maps.

The feature is an extension of the firm's Street View technology, which already lets users view 360-degree exterior images.

The existing service prompted some privacy complaints from people who claimed the technology was intrusive.

However, Google said the new scheme was on a completely voluntary basis.

"Building on the Google Art Project, which took Street View technology inside 17 acclaimed museums, this project is another creative implementation of Street View technology, to help businesses as they build their online presence," said a company spokesman.

"We hope to enable businesses to highlight the qualities that make their locations stand out through professional, high-quality imagery."
