Alexander,
Thanks for the reply. That sounds like the best way (cutting at 180) to do it for us. We are using GCS and also these polygons are global coverages that differ, so there will always need to be a break somewhere, so I don't think using a different projection would work. I do like you break idea, though. In fact, now that I think about it, it think that is what ArcGIS might do when creating a buffer that crosses the dateline. Thanks again!
