Each map has a purpose and reflects a level of understanding. Both of those change as time goes on.
Consider your "personal map" of your neighborhood. That is, the places that you know how to get to without guidance from anyone else. Think, too, of the places you could give directions to. Now, consider how that map has changed as you have grown older. Consider how that map changes if you have reference to the maps other people produce. The process you are asking about is the same.
