: How Google has mapped whole earth?
In: 0
If you’re asking about satellite views, they didn’t. They license that data from other companies.
As for Street View, they can hire/contract people do drive around specific routes, or even walk/boat/whatever places that are not accessible by car. The street maps were already there (again, licensed from another company) so all they needed to do was come up with an algorithm, which is what Google is _really_ good at.
Remember that Street View took many years to complete, is far from being up to date, and there are still places you _cannot_ see on street view — the entire neighbourhood I live in, for example!
