iOS GPS Distance Calculations between 2 locations

I created an app that shows the distance between 2 iOS devices. I got the coordinates using GPSKit and computes the distance using ZFHaversine. Both of them are libraries from cocoapods.org.

Now my problem is even if the device are placed side by side, the distance registered is +/- 70 meters. I am trying to find a way to make the computed distance, at least into +/- 5 meters.

Thanks in advance.

Solution

  • Just to update, for now I have used the Equirectangular Approximation formula on the ZFHaversine pod. This is more accurate on shorter distances.

    Thanks
