    How can I draw a line between 2 locations following the great circle?
    (At the moment, i am planning to add multiple line segments instead of a nicely single curved line.)

    Thanks for your assistance,

    Hi Henri,

    As I understand you want to plot a linestring representing the great circle route between two points rather than simply a straight line on the map. Here is shown how to make the great circle calculations to gain an array of LatLong points You
    can use this array to draw the desired line as it is shown here
