Whether you are on a road trip, looking for an aerial view of your home town, or looking for public transport updates, Google Maps may be your best partner. This web mapping tool lets you to sneak in street maps, locate businesses, decide the shortest route, and even visit streets in 3D. But there are a few of the interesting facts that you may have never imagined about Google Maps.
Google has around 20 Petabytes of data which includes aerial, satellite, and street level imagery across the world. That data equals to around 21 million GB or even 20,500TB of data.
According to the availability of data, satellite and aerial images are updated in every two weeks. Google updates Street View images as soon as possible though it was unable to provide proper schedules, because of different factors like driving conditions, weather etc.
Sometimes, users have reported unpleasant and odd moments on Google Maps, especially on Street View. The team quickly reviews and takes action. Users can click “Report a Problem” to report an image at the bottom and those requests are monitored regularly and responded by Google staff.
Google uses automatic license plate and face blurring algorithm to protect privacy of people in Street View and users can also ask for extra blurring. Aerial images provide much less resolution and detail.
For both Google Earth and Google Maps, the satellite images come from various third-party providers and sources. One can access the same information who buys or licenses it from different government, public, private and commercial sources.
Owners of the satellites used by Google may prefer to blur some areas before aerial images and satellites reach Google. Governments may want to file the petition for satellite owners to blur some sensitive areas. Street View is available only for public places.
