Aloha.
You might want to consider simply using Great Circle distances and then
refining that if you need something better.

I agree with Hernán, that you are probably better off using ellipsoidal
(geodetic) distances rather than projected distances for such large tracks.
Of course, you can use whatever projection you want to RENDER the routes. For
example you can use a conic projection to render the bird tracks or

Hi there, Mike et al,
thanks,
but if you check up with Thomas Alerstam from Sweden - as a bird tracking

this one for starters.
Hi Mike,
I am glad this helped you.
I am going to punt on this since a similar question about how to do routes in

That said, my initial thought is that instead of using

In my tests QGIS uses installed fonts but you will have to distribute them
yourself.
I think it might be beneficial for the QGIS to read fonts made available
with the QGIS Resource Sharing Plugin though, so a feature request may be
in order (I don't think this is currently supported, but someone

Not sure if I completely understand your question. I think QGIS supports

For measuring the kind of distances you are mentioning I would suggest
using ellipsoidal (geodetic) distances rather than projected distances.
This is because projected distances can become very inaccurate over
large regions (depending on the particular projection of course).
If

Just want to add that shapefile itself has size limitations and is not a
good format for these types of large datasets (or anything really), so
I'd suggest using PostGIS>Geography data type.
Cheers.
