Most cartographic blunders reflect a combination of inattention and inadequate editing. It will not to assure that the map marker is deliberate to make some blunders. Therefore, by definition a blunder is not a lie, but the informed map user must be aware of cartographic fallibility, and even of a bit of mischief. Errors are more common on derivative maps-that is, maps compiled from other maps-than on basic maps compiled from air photos and other primary data. However, some map makers is deliberate to make some blunders for some purpose such as advertising and political …show more content…

Unlike A's maps, B's maps always name C. If B feels better prepared for battle or believes internal turmoil has weakened A, B's maps might more boldly deny political reality by graphically annexing C. Neutral countries tread a thin cartographic line by coloring or shading the disputed area to reflect A's occupation and perhaps including in smaller type a note recognizing B's claim. If A and B have different names for C, A's name appears, sometimes with B's name in parentheses. (Even when recapture by B is improbable, mapmakers like to hedge their bets.) Cartographic neutrality can be difficult, though, for customs officials of nation B sometimes embargo publications that accept as unquestioned A's sovereignty over C. If As rule is secure, its censors can be more
