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 in 2007 in several cities in the United States, and has since expanded to include cities and rural areas worldwide. Streets with Street View imagery available are shown as blue lines on Google Maps.

Google Street View displays panoramas of stitched images. Most photography is done by car, but some is done by trekker, tricycle, walking, boat, snowmobile, and underwater apparatus.

History and features

Street View had its origins in 2001 with The Stanford CityBlock Project, a Google-sponsored Stanford University research project. The project ended in June 2006, and its technology was folded into StreetView.^[1]

• 2007: Launched on 25 May in the United States using Immersive Media technology.
• 2008: In May Google announces that it was testing face-blurring technology on its photos of the busy streets of Manhattan.^[2] The technology uses a computer algorithm to search Google's image database for faces and blurs them.^[3] Street View integrated into Google Earth 4.3, the Maps application on the Apple iPhone, and the Maps application for S60 3rd Edition. In November, the drag and drop Pegman icon is introduced as the primary user interface element for connecting from Maps's 2D view into Street View's 3D view. When Pegman is dropped onto a particular set of coordinates in Google Maps for which Street View data is available, Street View opens and takes over the whole map window.
• 2009: Introduction of full-screen option. Smart Navigation introduced allowing users to navigate around the panoramas by double-clicking with their cursor on any place or object they want to see.^[4]
• 2010: Indoor views of businesses available.^[5] Google invites users to contribute panoramas of their own using gadgets with Android 4.2. Google highlights user-contributed panoramas with blue circle icons on Maps. The company also created a website to highlight places in the world where one can find them.^[6]
• 2013: Business interior views are shown as small orange circles. Businesses such as shops, cafés and other premises can pay a photographer to take panoramic images of the interior of their premises which are then included in Street View.^[7] Google sets up program to let third parties borrow the Street View Trekker (a backpack mounted camera) and contribute imagery to Google Maps.^[8]
• 2014: Street-level imagery from the past can now be seen, if available for a given street view.^[9]
• 2015: A partnership was announced between Street View and the environmental monitoring company Aclima. Cars began carrying sensors to detect pollutants such as nitrogen dioxide, ozone, and particulate matter.^[10] In October, support for Google Cardboard was announced allowing users to explore street view in 360 degree virtual reality.^[11]

Implementation

Street View is available as a component of Google Maps, as a web application, and as a mobile application for Android and iOS. Originally, Google Maps used Adobe Flash for Street View.^[12] Google overhauled Google Maps in 2013. The newer version uses JavaScript extensively and has a JavaScript application programming interface.^[13] The new Google Maps and Street View are slower than the old version.^[14][15] A user can switch to the old version of Google Maps, which is especially useful when Google Maps is more sluggish than usual.^[16][17]

Data capturing equipment

• Cameras: Street View imagery has come from several generations of camera systems developed in-house.^[18] The cameras contain no mechanical parts, including the shutter, instead using CMOS sensors and an electronic rolling shutter. Widely deployed versions are:
  • R2: the earliest photos were captured with a ring of eight 11-megapixel CCD sensors with commercial photographic wide-angle lenses.
  • R5: uses a ring of eight 5-megapixel CMOS sensors with custom low-flare lenses, plus a fisheye lens on top to capture upper levels of buildings.
  • R7: uses 15 of the same sensors and lenses as R5, but no fish-eye.
• Positioning: recorded photographs must be associated with accurate positioning. This is done via a Global Positioning System, wheel speed sensor, and inertial navigation sensor data.^[18]
• Laser range scanners from Sick AG for the measuring of up to 50 meters 180° in the front of the vehicle.^[19] These are used for recording the actual dimensions of the space being photographed.
• Vehicles: data recording equipment is usually mounted on the roof of a car. A Trike (tricycle) was developed to record pedestrian routes including Stonehenge, and other UNESCO World Heritage sites. In 2010 a snowmobile-based system captured the 2010 Winter Olympics sites.^[18] Trolleys have been used to shoot the insides of museums, and in Venice the narrow roads were photographed with backpack-mounted cameras, and canals were photographed from boats.^[20]

Pegman

As noted above, the drag-and-drop Pegman icon is the primary user interface element used by Google to connect Maps to Street View. His name comes from his resemblance to a clothespeg. When not in use, Pegman sits atop the Google Maps zoom controls. Occasionally Pegman "dresses up" for special events or is joined by peg friends in Google Maps. When dragged into Street View near Area 51, he becomes a flying saucer. When viewing older views, the Pegman in the minimap changes to Doc Brown from Back to the Future.

Pegman has occasionally appeared as a costumed character at Google events, such as the launch of Street View in France in 2008.

Privacy concerns

Google Street View will blur houses for any user who makes a request, in addition to the automatic blurring of faces and licence plates.^[21] Privacy advocates have objected to the Google Street View, pointing to views found to show men leaving strip clubs, protesters at an abortion clinic, sunbathers in bikinis, and people engaging in activities visible from public property in which they do not wish to be seen publicly.^[22] Another concern is the height of the cameras, and in at least two countries, Japan^[23] and Switzerland,^[24] Google has had to lower the height of its cameras so as to not peer over fences and hedges. The service also allows users themselves to flag inappropriate or sensitive imagery for Google to review and remove.^[25] Police Scotland received an apology for wasting police time in 2014 from a local business owner in Edinburgh who in 2012 had staged a fake murder for the Google camera car by lying in the road "while his colleague stood over him with a pickaxe handle".^[26] In May 2010, it was revealed that Google had collected and stored payload data from unencrypted Wi-Fi connections as part of Street View.^[27] German authorities are considering legal action while the Foreign Minister said "I will do all I can to prevent it." Australian police have also been ordered to investigate.^[28]

The concerns have led to Google not providing or suspending the service in countries around the world.

• Australia: In 2010, Google Street View ceased operations in Australia, following months of investigations from Australian authorities.^[29] However, this cessation has since ended, with Google announcing plans to continue production on May 4, 2011^[30] and subsequently releasing updated Street View imagery for Australian towns and cities on July 27, 2011.^[31]
• Germany: In 2011, Google stopped taking Street View images in Germany.^[32]
• India: In 2011, Google stopped taking street images in India, after receiving a letter from the local authorities.^[33]
• Canada: Street View cars had been spotted as early as September 2007, in Montréal, though service for Canada was delayed while attempting to settle with the Canadian government over its privacy laws.

Third-party use of images

Fine-art photographers have selected images for use in their own work.^[34] Although the images may be pixelated, the colours muddy, and the perspective warped, the photographs have been published in book form and exhibited in art galleries.^[35] Michael Wolf won an honourable mention in Daily Life in the 2011 World Press Photo competition for some of his work using Google Street View.^[36] Mishka Henner was short-listed for the 2013 Deutsche Börse Photography Prize in November 2012 for his series 'No Man's Land', which depicts sex workers at rural roadside locations.^[37]

Swedish programmer Anton Wallén developed a game called GeoGuessr, which places players into a Google Street View and has them guess its location.^[38]
