Hello, I am plotting flight paths between Airports that I have Latitude and Longitude values for onto a Google Map (v3 of the API).

However unlike v2, v3 does not seem to have an option to put a Polyline on the map between two points and have it display as the great-circle flightpath.

So what I was thinking, was that it might be possible to calculate a number of points along a great-circle path between two Latitude/Longitude points.

I'm terrible with maths and I can hardly understand or comprehend how the great-circle calculations work. Does anyone know of a C# library or code snippit that can take two latitude and longitude points and calculate a number of points along the great-circle path between them ?

You can find a library included in the Windows Mobile 6 SDK

Take a look at Mike Gavaghan's C# Geodesy Library.

It looks promising however it seems to be able to calculate distances and bearings between points, but not calculate a number of points between two points.

I'd be surprised if the library doesn't provide for calculating points, too.
