[ferret_users] How to draw a box to represent the regional-scale study areas in a field over a larger area?

[Yun.Li@xxxxxxxx]

Dear Ferret users,

Could you please let me know how to draw a box to represent the regional-scale study areas in a field over a larger area?  

More specifically, for example, I want a ferret plot for areas: (1) Southwest Western Australia (SWWA, southwest of the line joining 30°S, 115°E and 35°S,120°E); (2) South Australia (SA, the box area bounded by 32°-36°S and 135°-140°E); (3) Victoria (VIC, the box area bounded by 37°-39°S and 143°-147°E), and then overlay it on a field (e.g., SLP in July 2009) over a larger area (20°N-60°S,  80-180°E)?

Thanks for your help.
