Longtitude and Latitude Question
I am currently working on this project at work and I need help. I have about 100 different variables with lats and long assigned to them. I used the equation below to find the distance from point a to point b, but now I am trying to come up with an additional equation that when I pick one of the variables, I can enter whatever miles I want and it will return all variables with lats and long within that circumference of the distance that I've entered. The equation I used for finding the miles is below:
=ACOS(COS(RADIANS(90- LATITUDE OF A)) *COS(RADIANS(90- LATITUDE OF B)) +SIN(RADIANS(90- LATITUDE OF A)) *SIN(RADIANS(90- LATITUDE OF B)) *COS(RADIANS(LATITUDE OF A- LONGTITUDE OF B))) *3958.756 |

Longtitude and Latitude Question
Mastermind4real,
You have a couple of errors in the last line (as displayed) of your formula. It should be Longitude A (not Latitude A) also the constant should be 3440.065 not 3958.756. -pb |
