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.
Example:
Example 1 - Identifying an observed density map
and a calculated density map
