title: C# Calculate n Number of Points along a Great Circle path between Two Latitude/Longitude points
body: <p>I am plotting flight paths between Airports that I have Latitude and Longitude values for onto a Google Map (v3 of the API).</p>
  
  <p>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.</p>
  
  <p>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.</p>
  
  <p>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 ?</p>
