Greetings everyone,

I am a novice IDL user and I have the task of displaying trajectories
with respect to a mapped projection of the earth. I am using map_image
to generate a projection of the earth with terrain, but I can't seem to
find what I would need to overlay a trajectory on top of that. I've
tried the PLOTS function, but since T3D is not specified it will only
plot lines against the surface and ignore the z component. I know I
could use SURFACE to get the transformation matrix I need for PLOTS to
operate correctly, but I'm not sure how to set it up to work with the
image that I have mapped. Am I on the right track, or is there
something better I could use?
