Working with coordinates (VB6)

[efratomer]

Hello,

I am trying to make something like an ATC viewing which will be connected to the pilots's FS via FSUIPC. Therfore, I want to display the traffic on the program's form and I need for somehow to draw the traffic to a X and Y coordinates from the normal ones in FS...

Anyway,

I need to get distance and angel from 2 coordinate, distance I have already managed to return, I have problem only with the angel.

Just to be sure... Im talking about those coordinates: N028.41.07.001 E034.03.45.000

Thanks in advance!

Omer.

I need to get distance and angel from 2 coordinate, distance I have already managed to return, I have problem only with the angel.

If the distance is not too far, i.e. the points are close enough to regard the intervening Earth's surface to be pretty flat rather than spherical, then isn't that merely a matter of simply right-angled triangle trig?

How did you determine the distance -- wasn't that by similar assumptions, then using pythoagoras?

Otherwise it gets more complex for both, as you need great circle calculations for the distance and some spherical trig for the angle.
