How can I get line features to appear as great circles on a map, instead of straight lines? Thanks,

You want to display a line as a circle? Considered computing the centroid of the line and buffer/increase it to your liking? –  Curlew Mar 4 '13 at 13:08
You need to give more information, in order to answer your question. What software are you using? How are you drawing these lines? How did you generate the lines? –  Devdatta Tengshe Mar 4 '13 at 15:13

I'm using Quantum GIS, and what I was hoping to get is when I draw a line between two points on a map, it would show as a great circle line (a curved line, depending on the current projection), and not as a straight line on the screen. –  user15749 Mar 5 '13 at 7:06
