 Dictionary entry overview: What does mapping mean? 

• MAPPING (noun)
  The noun MAPPING has 2 senses:

1. (mathematics) a mathematical relation such that each element of a given set (the domain of the function) is associated with an element of another set (the range of the function)

2. (genetics) the process of locating genes on a chromosome

  Familiarity information: MAPPING used as a noun is rare.
