a question about topography shading

Hi All,

       I am trying to use NCL to make a plot with filled contours
overlapping with contour lines base on some NCEP 850mb fields, and
meanwhile, I want to have some topography feature shaded (e.g. Tibet
Plateau). NCEP 850mb fields have values extrapolated over the Tibet
Plateau. So I have to set them to NaN and meanwhile shade the area. I am
wondering, instead of manipulating original data, whether there is a
quick and convenient way to do this in NCL? E.g. is there a buil-in
topography files we can directly pull out?

       Thanks a lot.
