For the rest of us, Google Maps is pretty much one step away from magic. How can it collect so much data about so much of the world? Who works to keep the maps maintained and updated? And what about real-time traffic conditions, temporary speed limits, and operating hours for nearby businesses? Let's look into the benefits — some new, and some old — which can help us make sense of the world around us. Why Did Google Launch Maps? But as I hint below, Google hopes that Maps will be able to do a lot more in the future.

Collecting Data for Google Maps When it comes to collecting data to help maintain and improve Google Maps, it seems there can never be enough — and the impressive bit is that none of that information is over three years old.

This is a project of immense scale. Street View Google Street View is a never-ending road trip. With a massive squad of vehicles dispersed around the planet, their aim is to repeatedly drive around every accessible road they can find — all the while taking degree photos everywhere they go. These additional reads are processed and turned into navigational and directional data that Maps can incorporate into its database.

This is also partly how Google has built its huge database of local business details. Satellites Another layer of Google Maps is its satellite view. These images are cross-checked with other layers of data, such as Street View as well as data submitted by external agencies. This helps Maps to pick up geological changes, new and altered buildings, etc.

Your location data can be used for things like real-time traffic updates, estimating current traffic speeds, and pinpointing road diversions.

Google also uses this data to estimate the hours when individual businesses will be busy. It does this by keeping tabs on the foot traffic in individual buildings. 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. And if you think you can get away with vandalism, think again: 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. 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 The Story Of Google: Algorithm and Functionality Updates Google released its very first algorithm update sixteen months after it went live, which was mostly undocumented.

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. 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. This is without doubt a huge task. 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: 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.

New routes are drawn by hand, roads are connected, new buildings mapped out, etc. This is a project that will never end. These all work together to offer the service that so many have come to rely on — a service that far exceeds the depth or quality of its competitors.

  1. Most maps should have a clear and concise title, a notation on the scale or if the map is not to scale , and, when needed for orientation, a north arrow. But as I hint below, Google hopes that Maps will be able to do a lot more in the future. Legibility depends on good decision-making for selecting symbols that are familiar and choosing appropriate sizes so that the results are effortlessly seen and easily understood figure 1.
