Re: overlay trajectory on satellite mapþ

Try moving your gsn_polyline call to after the overlay call:

gsn_define_colormap(xwks,"amwg") ; define colormap
plot = gsn_csm_map(xwks,res)
plot_rad = gsn_csm_contour_map(xwks,data_4,res)
overlay(plot, plot_rad)
gsn_polyline(xwks,plot,longi,lati,res)
draw(plot)
frame(xwks)

Note also that you are using your regular plotting resource list (res)
in your gsn_csm* calls and your gsn_polyline call. It is highly
recommended that you develop a separate resource list for gsn_polyline:

resp = True
resp@tfPolyDrawOrder = "PostDraw" ; draw the trajectory at the end

Finally, you are also setting the following:
res@mpFillDrawOrder = "PostDraw" ; draw continental outline last
res@mpOutlineDrawOrder = "PostDraw" ; draw the map outline last
res@mpGridAndLimbDrawOrder= "PostDraw" ; areas before map gets set
res@mpPerimDrawOrder = "PostDraw" ; areas before map gets set

These might conflict with the drawing of the trajectory. Thus, you might
have to alter some (or all) of these to Draw if you continue to have
difficulty getting the trajectory on there...
Good luck, Adam
