Just for information, can you reproduce formulae for both rhumbline and great circle navigaition.

Hi @Shreyasq,

You can use the following command to understand the formulae used by "legs" to compute the distance in both great circle and rhumb line tracks.

open legs

In “legs.m”, we can see that for calculating the distance, it calls the "distance" function at line 81. The implementation of "distance" contains the algorithm for computing the distance between the two points. Open the file using the following command.

Hope this helps with the information you need!
