Check out the MAP_PROJ_* functions which will transform your coordinates
back and forth between cartesian and lat/lon. You'll then (depending on
your map data) pass your transformed map vertices to IDLgrPolyline or
IDLgrPolygon which can be added to a model then then the view which
contains your contour.

The trick will be aligning the map and contour objects on the same space
in your coordinate system. Look into the *COORD_CONV keywords to your
IDLgr* objects.
