I have two latitude/longitude points. They are really close together. What I want to do is find the difference between the two longitides and calculate how many yards that would be. If I did the calculation with with the two latitudes, it would be just 2025yds per minute of latitude. However, for the longitude; being that the closer you get to the poles, the closer the lines of longitude move together, you have to apply a conversion to it.(adsbygoogle = window.adsbygoogle || []).push({});

If my lat/longs were 34.34°W, 79.1°N and 34.23°W, 80.3°N Respectively, I want to find the exact amount of yards between my two lines of longitude.

If any one had the formula to find out how many yds per minute of longitude according to what latitude I am at, I would greatly appreciate it.

Thanks,

Mike
