I created a polygon in Google Earth and saved to kml. After importing as a vector layer, where the polygon crosses the prime meridian, the polygon wraps around the world.
So far, I have figured out that I need to change the projection [and offset?], but I cannot figure out how to do that.
I am new to QGIS (and GIS in general). I have already spent many hours trying to figure this out. Can somebody please help?
