I guess the terminology originally is taken from mathematics. A map is
a mathematical concept, similar to a function. Perhaps you should say
that a function is a map, rather than the other way around. Sometimes
people say a mapping instead of a map. They may also use the word as a
verb, saying that they map things. Other languages use words meaning
image or reflection for the same concept. And why not, a (geographical)
map is an image that reflects reality.
