how does google maps works

Google maps is used by numerous people on daily basics while traveling as the navigation platform effectively predicts traffic and plots routes for them.

more than million kilometres may driven on daily basics in 220 countries.

How does google maps work.

• Google maps uses machine learning in combination with various data source including aggregate location data, historical traffic patterns, local government data, and real-time feedback from users, to predict traffic.
• google maps make use of Dijkstra's algorithm to find the shortest paths between nodes in a graph, which may represent road networks.
• google maps gets its images from satellite and aerial images in google Earth are taken by cameras on satellites and aircraft, which collect each image at a specific date and time. 
• Geo-spatial data visualization company and a real-time traffic analyzer, Google Maps was launched in February 2005. 
• Map maker was added to the american version of google Maps, allowing any viewer to edit and add changes to google maps. This provides Google with local map updates almost in real-time instead of waiting for digital map data companies to release more infrequent updates.
• Early versions of Google maps relied only on data from traffic sensors, most of which were installed by government transportation agencies or private companies that specialize in compiling traffic data. 
• using radar, active infrared or laser radar technology, the sensors are able to detect the size and speed of passing vehicles and then wirelessly transmit that information to a server.

Google maps uses an international connection to a GPS navigation system to provide turn by turn voice guided instructions on how to arrive at a given destination The application requires connection to internet data  and normally uses a GPS satellite connections to determine its location.

Data operation team staffed all over the world that plays a role in just about every aspect of map-making from gathering street view images and getting authoritative data sources to correcting the map for inaccuracies and training machine learning models.

Interesting facts about Google maps.

1. Google maps has over 20 petabytes of data, which is equal to approximately 21 million gigabytes, or around 20500 terabytes.
2. Google has worked with thousands of business owners in eight countries to bring street view technology inside buildings.
3. Google maps doesn't use much mobile data at all when navigating. most of google maps data use is incurred when initially searching for the destination.
