You can find online documentation for 'mapitd' at:
http://ngwww.ucar.edu/ngdoc/ng/supplements/ezmap/#MDPITD
As the documentation states, 'mapitd' is very much like the 'mapit'
function, except it does its work with a different underlying drawing
library:
"... except that it uses the new dash package DASHPACK instead of the
old DASHCHAR; it attempts to omit non-visible portions of lines and to
handle "cross-over" - a jump from one end of the map to the other caused
by the projection's having slit the globe along some half of a great
circle and laid it open with the two sides of the slit at opposite ends
of the map. Cross-over can occur on cylindrical and conical
projections; MDPITD handles it gracefully on the former and not quite so
well on the latter."
The most up-to-date version of NCAR Graphics is v4.3.1, please see:
http://ngwww.ucar.edu/ng/download.html
if you want/need to upgrade your current version. You can determine your
currently installed version by typing the command:
% ncargversion
