Ron,
I have never before seen the sort of plotting sheet you attached to your post. I presume the dashed lines at the bottom - which are rather like two piece of pie, facing each other point-to-point - help me determine the width of a degree of longitude. But I can't quite picture how they are used. Could you comment on this?
The type of plotting sheet I am accustomed to is attached. Yours is more visually interesting, to be sure.
Thanks,
Bob
