[Qgis-user] QGIS airlines: connecting airports with lines ?

[C Hamilton]

The "XY to Line" tool in the "Shape Tools" plugin can draw the lines. Just
prepare your data so that there are starting and ending latitudes and
longitudes and "XY to Line" will do the rest. It draws the shortest path
between the two points which gives the curved appearance.

Good luck,

Calvin
