Google Street View is a technology featured in Google Maps and Google Earth that provides panoramic views from positions along many streets in the world. It was launched on May 25, 2007, in several cities in the United States, and has since expanded to include cities and rural areas worldwide.
Where available, Street View images appear after zooming in beyond the highest zooming level in maps and satellite images, and also by dragging a “pegman” icon onto a location on a map. When dragging the pegman icon, blue lines on the map showing Street View imagery will appear.
Using the keyboard or mouse, the horizontal and vertical viewing direction and zoom level can be selected. A solid or broken line in the photo shows the approximate path followed by the camera car, and arrows link to the next photo in each direction.
At junctions and crossings of camera car routes, more arrows are shown. By using Google Maps, users can turn on steroscopic 3D mode by right-clicking in Street View to get an anaglyph version of any Street View images. However, this mode requires users to wear red cyan glasses to see the 3D effects.
