    Once EZMAP is initialized by a call to MAPDRW (which actually draws a
    basic map) or MAPINT (which just precomputes some numeric quantities that
    will be needed and readies the package for use), one can draw objects on
    a map that are defined by lat/lon coordinates. The principal routines of
    interest are MAPIT (also known as MDPIT) and MAPIQ (also known as MDPIQ),
    but there are some other routines that might be of use.

    See the section of the EZMAP programmer document titled

      Routines Used to Draw Objects on a Map

    at

      http://ngwww.ucar.edu/ngdoc/ng4.3/supplements/ezmap/#DrawObjects

    as a starting point.

    The next section, titled

      Routines Used to Draw Solid-Filled Maps (EZMAPA)

    mentions the routines MAPITA, MAPIQA, MAPITM, and MAPIQM, which can be
    used to add objects defined by lat/lon coordinates to an area map and
    subsequently color-fill them.

    The example "mpexfi" shows how to call MAPIT and MAPIQ, though in a bit
    frivilous way. If need be, I could create a better example for you ...
