Data has to be accurate. Inaccurate data is worse than missing data 
(although, it must be noted that imprecise is not the same as 
inaccurate, and we can tolerate a reasonable amount of imprecision 
provided it is not misleadingly imprecise).

As far as a map is concerned, something is relevant if it is there. Even 
if only one person a year actually wants to know it's there :-)
