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

[Alex Mandel]

It's not super hard.
1. Download the data
2. Import it to GIS (probably comes in text file, so some conversion
will be needed.)
3. Densify the lines, or create lines between the pairs of airports.
Point 2 Lines plugin should help. You need to make sure to add nodes
along the way (Densify), otherwise the lines won't curve nicely. There's
a little trial and error to get them dense enough without making to many
nodes.

I used this data set for a cartography class 5+ years ago, it's a fun
one. You can see a couple of examples here

Enjoy,
Alex
