Have you ever been out of the metro by running for a meeting without knowing where to go? Sure, Maps will let you know how to reach your appointment, but only if you know where you are and in which direction you are going. Sometimes he thinks he knows them, although in fact the data he has is not enough. And then the following happens: You try to figure out which path to follow by checking whether the blue dot is moving in the same direction you want to go. If this is not the case, probably your compass is not set, so you press the brake and go in another direction and see if you are going to the right road. Then you walk for a while and the dot suddenly "moves" 2 squares away. If you are in a busy city, GPS accuracy is declining due to all of these very high blocks of flats. Do not worry, however, you will find a sign to locate and move your location manually on the map and eventually arrive late with 15 minutes.
Google is well aware that we do not want to waste our time in the era when everything is running too fast, so it has found a solution called Global Navigation to combine camera data, GPS Compass and the compass to determine your position more accurately.
This technology is based on the method of the optical positioning system, which creates maps by combining images of the regions so that their outlines and characteristics can be used for navigation. Thanks to Street View images, Google has created a detailed VPS index so that devices can accurately determine their location and orientation based on what's around them. They will also use mechanical learning so that phones know what reference points they will look for, as the original images could have been taken during a different period or from another angle.
Google is still working to improve this technology before making it widely available. It has already begun to test it with selected Local Guides, along with navigation based on AR, but it will probably spend some time to improve it before embedding it in the official Maps app.
