[Matplotlib-users] Basemap:'snapback' on line crossing global plot edge

[James B. <bo...@ll...>]

This is probably for Jeff but maybe someone else has an answer.
If I plot a satellite orbit on the globe when the groundtrack passes  
the edge of the map - in this case the Greenwich meridian  - the  
line  'snaps back ' across the plot where the line picks up on the  
other side of the globe.
The attached plot shows the problem, note the line across the  
northern polar regions. I have encountered this before. In this case  
I can break the ground track into two segments, one up to and  
including Greenwich and the other from Greenwich eastward.

My question: Is there a more elegant way to deal with this situation  
in Basemap? I have a nagging feeling that Jeff has addressed this  
issue but I cannot find anything in the examples.
