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

You want to display a line as a circle? Considered computing the centroid of the line and buffer/increase it to your liking?– CurlewMar 4, 2013 at 13:08

2You 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 TengsheMar 4, 2013 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.– user15749Mar 5, 2013 at 7:06

All comments look great but let me draw your attention to new Beeline plugin (Oct.2017~).
Probably no explanations are needed. Enjoy!

2Actually, I find the Shape Tools plugin to better suite my needs, as it converts line features to great circle arcs. Dec 4, 2017 at 10:22
