How Google Maps Works

In this blog, I am going to talk about how Google maps works for the society. Google map is a basic and free web mapping service application and technology provided by Google Company. The Google map provides three different kinds of maps for people to choose. These three maps are Euclidean vector, satellite imagery (the same image as Google Earth) and the Terrain.
The Euclidean vector map is the most traditional maps which can provide for transportations, administrative division and the commercial information for the society. For instance, people can figure out the NSW province and Queensland province’s border on the Euclidean vector maps. The map will also provides the streets, avenues, roads and blocks names on the maps such as George Street and Pitt Street. The map gives the drivers lots of the information about the high-way and helps the drivers to find out the shortest way to their destination. The map can work just as GPS system.

People can also use the Euclidean vector map to see the pictures of the street or the important landmark building. Without leaving their house, people can still see many different places at home. For example, people can use the Google map to see the Harbour Bridge in Sydney or the Disneyland in US on the Internet.

If people enlarge the maps big enough, they can directly see the specific photos on the screen. People can see the 360° sight around one photo. People can still enlarge the photos to see more clearly. This function helps people to know the real spectacle in even a small area. For instance, people can use this function to see a small block’s photo.
