Google map how does it work

Recommended blog - 7 Top Trends in Augmented Reality. Google Maps lets you find the nearest coffee shop or hospital, but also lets you explore the solar system when you have the time.

Getting stuck in traffic is a horrible experience. Google Maps helps you to avoid that hell-hole of automobiles letting you know which routes have the most traffic and which routes have the lightest traffic. Google Street View tries to offer you an experience that emulates being at a place as close as they can.

Google Maps offers degree panoramic photographs at the street level at various locations all around the world. Being listed on Google Maps with accurate information is now a crucial factor for any company with a brick-and-mortar location. The free advertising is amazing. And users get to find what they want along with the directions to it.

Users can add reviews and photographs to the listing. But one of the most beneficial features is that people can see what time a place opens and closes, and even what time and day is the busiest at that place.

If you open Google Maps on your computer and go to Globe View, you can see the Earth as a satellite would. You can spin it and zoom into places, and even look at other planets in the solar system. Google Maps work because of what Google does best. Data collection.

The working of maps is based on the simple principle of collecting an exhaustive amount of data and then processing and presenting it to the world. From government agencies to end users, Google Maps uses the data collected from a massive amount of sources to keep the system up to date. Different components that contribute to the working of Google Maps. Google Maps collaborates with other organizations to get data on places of interest, new roads, aerial imagery, transit routes and schedules and fares, etc.

The problem with using third-party sources is that governmental restrictions and policy changes can have an adverse impact on map quality. Problems also arise when marking borders for disputed territories. Google Earth and Google Maps use satellites to capture views from above. Satellite views are also used for verifying data collected from other sources, making sure they were not incorrectly reported or out-of-date.

Satellites capture street markers, building locations, spacing, etc. Apart from letting you see the top-down view of your house when you select satellite view, this imagery can be overlaid on base maps to show building shapes in the normal 2D map view. Crowdsourcing for mapping is especially important in developing countries, or countries with government restrictions, where Google may not be able to directly obtain accurate data. Earlier, Google Maps had a feature that let users make edits to maps, but that feature was withdrawn from the main mapping platform after reports of vandalism.

The Local Guides community helps in adding additional information to maps, but not indirectly editing maps. Business Listings are usually generated from sources.

But to avoid duplicate entries, merging of entries, and inaccurate information, businesses are encouraged to make use of the Google My Business tool, to register their business and provide up-to-date information.

Large Businesses in the US even include indoor directional information. User contributions provide additional details to businesses like reviews, photos, and opening and closing times. Google data shows that users submit more than 20 million contributions each day. User-generated error reports are also integral for finding out errors that cannot be identified without human assistance.

A bit creepy perhaps, but it's yet another attempt to bring that offline information online. Google Map Maker is another way in which Google is crowdsourcing its Maps operation, and this is a program that's been around since among Google's many others.

The good news is that most of this functionality is being incorporated into Maps itself, and Map Maker will be shut down for good in once the transition is complete. In short, users can edit Google's maps with their own personal contributions. You're able to add and edit places, new roads, building outlines, and hiking trails. And if you think you can get away with vandalism, think again: user edits can be reviewed by other users. This is especially useful for mapping hard-to-reach places and for gathering knowledge that would otherwise be out of Google's reach or awareness.

As well as its army of editors, Google also has millions of so-called Local Guides. Local Guides is a feature that will remind you of Foursquare and is Google's attempt at collecting a layer of more subjective data to lay over its base map. When you're in Google Maps, go to My Contributions and you can search for different places in your area. By leaving a review, answering a few questions, and submitting a photo, you can contribute to this additional layer of data.

This local knowledge helps Maps to know things like the vibe of a cafe, whether a hotel has parking, or whether a restaurant has vegan options. In return for contributions, users can earn rewards like increased storage on Google Drive. As you can see, the amount of data being collected by Google is astonishing -- and we haven't even touched on some of the other service integrations, such as with Google's business listings.

These layers of data, when processed, are what give us access to all the information found on Google Maps. But what actually goes into making sense of all that data? This largely boils down to the kinds of algorithms that make up the bedrock of Google as a company.

These algorithms, which happen to be extremely complex and secretive, work to clean the data, spot inconsistencies, and link it all together to make it more useful. For example, when Street View scans images for road signs and business names, algorithms may try to make sense of road networks by interpreting those road signs. At the same time, location data may be taken into account when calculating fastest routes from A to B.

Although algorithms are always improving, they can only do so much, so all of this data is also combined with a ton of human involvement. If there's something Google's algorithms can't make sense of, a team member will manually look it over and set things straight.

Often, intersection logic is inputted manually and new roads are "massaged" into place. This is because sometimes the best way to understand what's seen on the road is to delegate the task to a human.

This is without doubt a huge task. That's why Google has teams around the world dedicated to keeping things up to date in every country in which it operates. Every day, masses of changes are made to Google Maps.

Some of these may be the addition of new places and new roads while other changes may involve fixing mistakes. Many of these are fixed by chance by members of the public: editing place descriptions, adding roads, and so on.

Yet on top of this, Google has a large team of people working through the thousands of reports that are filed to Google each day. A good chunk of these reports are reviewed and acted on manually. These images are then referenced with Street View and base map data, resulting in a single application that can provide you with a glimpse of the entire world with a tap on a screen. As the two products continue to converge, the differences between them are narrowing down to a blur, though they still form an important distinction.

For the sake of improving user experience. Google Maps asks for access to the location data on your phone. Using this information adds yet another dimension to the product, providing users with such things as real-time traffic updates and so on. These little things help implement more features into the already intricate mapping service, making your everyday life a little more easy. While the inner workings of the system get more and more complicated the deeper you dig in, this is an overall view of how the system really works, and how it gathers and processes the data it needs.
