I have figured this out so please disregard the thread
to convert from chordal distance to greater circle
2*arcsin(distance/2)*Radius
I apologize if this is posted in the in the wrong place (i figure either here or calculus)
Assume unit radius
this is what i know - I have a latitude and longitude and I can convert these to Cartesian coordinates like this
first convert lat and lon to radians by multiplying by pi/180, then
To convert back to lat lon i do this
What I am trying to figure out is
If i give you a distance between two points defined in cartesian space on a unit radius sphere how do i convert that distance to lat lon in degrees
Hope this makes some sense
