What is Google Maps?
Google Maps is a web mapping service application and technology by Google. It is used by Google to power many of its other products, such as the Google Maps website, Google Ride Finder, Google Transit, as well as the maps embedded on third-party websites via the Google Maps API. The application also provides satellite images that are superimposed by the maps. However, it should be noted that the satellite images are not updated in real times; instead the images are months or even years old in some instances.
How is Google Maps used?
When Google Maps is opened, it shows the user a map of the user’s country. The user can then either zoom out to view a world map, or zoom in to a particular location. The user can also search for a particular location. The view can be changed from a map to satellite images that also show the map superimposed on the images.
How and when was Google Maps started?

Google Maps then started offering satellite images and directions in April of the same year. In the same month, it was launched in the United Kingdom, hence expanding its presence to Europe.

How does Google Maps work?
Google collects data from certain agencies, such as the Census Bureau, from geological surveys, as well as Google's Ground Truthers, which are responsible for getting the Street View cars' tracks and imagery. This among other sources mainly provides the information for the maps. Furthermore, people and users can update the information regarding business, and locations in their vicinity.
All this information is uploaded to Google’s servers, where various algorithms are run to make sense of this data. The output is the map that is generated for the users.
