Android Question GPS library DistanceTo seems wrong

[shb777]

I added this code to my dji app so I could display distance 0n my app:

Sub CaculateDistance
   
    L1.Latitude=HomeLocationLatitudeMavic
    L1.Longitude=HomeLocationLongitudeMavic
    L2.Latitude=LatitudeMavic
    L2.Longitude=LongitudeMavic
    DistanceBetweenMavicAndHome =    L1.DistanceTo(L2)
   
End Sub

It seems to be way off. The remote control is showing a distance around 4 times greater, and I think the remote control is right.

The distance measurement is always in 2D, if you need it in 3D then you have to calculate differently.

Good old Pythagoras and his friend Haversine strike again !!

i think it's returning meters rather than feet
