Hi all,

How can you plot southern longitude and latitude (few) in the northern map?

I know there should be a way but I have tried and failed. I hv done map

projection but I am not winning yet

Any suggestion will be welcomed.

Thanks
Zolile

I do not work with maps in IDL ever, and I do not really know what the problem is without seen a short example, but couldn't you just multiply latitude by -1?

I do work with maps in IDL, but I don't understand what you're trying to do.

Providing a minimum working example is best way to get a little help!
