[ncl-talk] drawing satellite passes(14 per day)

[Adam Phillips]

Hi Ipsita,
I do not see anything amiss with your script. However, I would definitely
comment out this line:
res at cnRasterSmoothingOn = True
As I believe that will really slow down your script.

If that does not fix the issue I would suggest the following:
1) set res at gsnDraw = True and res at gsnFrame = True.
2) Comment out the overlay(PLOT,plot), draw(PLOT) and frame(wks) lines.
3) Change the output format from pdf to png

Do you get each swath drawn on its own frame correctly?

As always, please respond to the ncl-talk email list.
Adam
