    Calculating small distances between lat/long coordinates using Excel

    *(Technical)* The most common GCS distance calculation, the Spherical Law of Cosines (SLoC), gives poor results at short distances. This is an issue when calculating joint lengths using latitude/ longitude pairs. At these short distances, the spherical law of cosines has a precision of only 4.5%. In contrast, the three alternate techniques I compare with…
