“Google lets users create own Street View” article
“Google has unveiled a new tool that allows users to create a Street View – a 360 degree virtual tour – of any place and share it using Google Maps. These can be created by using photos taken by an Android phone or DSLR (digital single-lens reflex) camera. The tool lets users connect various photos and, once published, people can navigate between them on Google Maps.”
Advice on taking the photographs and turning them into a spherical set (a “photo sphere”) is given here.
