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. --Jim |
