I would like to draw a great circle arc on maps.
The function drawgreatcircle() in Basemap is usefull as long as you know the latitude and longitude of the starting and the destination points on the map.
My problem is that I have the starting point and a bearing in degrees referenced to the North pole.

I think there's no equivalent function for your needs. You could however, derive the lon/lat-values of the end point mathematically (knowing the northpole-referenced bearing) and assign these to the drawgreatcircle()- function.
