[QUOTE="Sooty, post: 6080715, member: 652764"] Reviewing my previous question, I believe I can 're-model' it in a way that is 'mathematically equivalent' and will so will allow me to continue with my project. It addresses the question in terms of Great Circle/Spherical geometry, which although I can find relevant articles on the internet, they present their maths in ways that are waaay beyond my understanding. So, instead of referring to anything about Coriolis, consider this: So. Knowing point [B]A[/B] on a sphere, where the position of [B]A [/B]is defined solely by [B]Lat[/B], where [B]Lat [/B]= Latitude in degrees (as before) And point[B] B[/B], whose distance from point [B]A [/B]is defined (not by [I][B]actual [/B][/I]distance travelled) by the angle[B] Asector[/B], Where [B]Asector[/B] = [B]Angle of the sector of a Great Circle[/B] path that runs between them. Now, the direction of point [B]B[/B] relative to point [B]A [/B]is [B]Dir, [/B]where [B]Dir [/B]= [B]Direction/Azimuth[/B] in 'compass degrees' - 0 to 360 (as measured at point [B]A[/B]) along the [B]Great Circle [/B]path. Questions:- what is the value of [B]Lat [/B]of point B? what is the value of [B]Dir [/B]at point [B]A[/B] relative to point [B]B[/B] on the great Circle path? - - - Hopefully, to clarify, if it's not already clear... 2 points on a Great Circle... [B]Lat[/B] and [B]Dir[/B] for each, obviously different... for my scenario, the distance between the 2 points is defined by the 'included angle' of the 'earth sector' covered, and [I]not [/I]by the distance between them on the Earth's surface...
