It just means that you may have found something using a Google search that isn't exactly right.
(Leaving aside such issues as the difference between "flat" and "level", the subjective nature of "steep", and the fact that you have not shared any links to allow other people to evaluate the validity of your claims. Which, it bears pointing, SG's posts have. Which is sort of the point. It isn't using Google as a search engine which matters, it is the content of what is found. The search engine only finds what is out there. Whether the content is good, bad, or indifferent is an entirely separate question.)
This isn't the fault of the search engine, just that of the material that was found when you used it. You seem incapable of discerning the difference.
Was that the
only map that a Google search disclosed? What made you choose to use
that one? Did you look for any others after you found that error? Did you report the error? Google Maps has has many crowd-sourced components and gratefully accepts corrections.
Did you think that
all maps are, or should be inerrant, gospel truth? I don't. Perhaps that is because my father was a geographer by profession and taught me at an early age not to do that, but it should be somewhat obvious even without such help.
