Yes it's sad but true that may be perfect map does not exits

I think I will have to give up this idea of getting a perfect map

May be in future , it will become possible.

It is very much a topic of the future. There are several science fiction novels written around it. Isaac Asimov has the Encyclopedia Galactica in his Foundation series. David Brin also has the Encyclopedia Galactica in his uplift trilogy. Gordon R. Dickson wrote a book called The Final Encyclopedia. It has been a dream for a long time. Some people consider The Library of Alexandria the first attempt at this.
