Try running this sequence, and see if the result is what you are
looking for:

iimage,dist(200),zvalue=0.
iimage,dist(200),zvalue=200.,/over,rgb_table=1
icontour,dist(200),zvalue=100.,/over,color=[255,0,0]
iplot,200*dindgen(20)/(19d0),100+100*cos(dindgen(20)*!
dpi*4/19d0),replicate(300,20),/over,color=[0,255,0],thick=3.

Are the slices images or plots? If plots, are they contour plots? What
are the approximate number of slices and their dimensions?

They are colored contour plots that I've put on a stereographic map
projection. In terms of slices, right now I'm just dealing with two
slices, but might add more depending on what I am trying to show. I
figure that once I've got two slices figured out, it shouldn't be that
difficult for me to add more. In terms of dimensions, are you asking
about the data limits(lat=[40 90], lon [-180 180]), the number of
pixels or?
