Hello,
I have been using the vincenty function to calculate
distances between latitudes and longitudes. I would now like to find
points that are X miles from a given coordinate.
Is anyone aware of a function that would calculate a latitude of a new point if all other inputs are know?
For example :
vincenty 41.75499 -124.194 ? -124.194, hav(5)
So I want to know the latitude of the point 5 miles away on the same longitude?
I looked at the code in the vincenty ado file and it is beyond my mathematical ability to calculate this number myself.
Thank you.
