Description:
       Data items in the MAP category record
              the details of a maps. Maps record values of parameters,
              such as density, that are functions of position within
              a cell or are functions of orthogonal coordinates in
              three space.
              A map may is composed of one or more map segments
              specified in the MAP_SEGMENT category.
              Examples are given in the MAP_SEGMENT category.
