CoordTrans distance measurement

[ColMacF]

In CoordTrans V2.3 there is the potential to measure distance between two points defined in the same system

What is this distance - assuming an output in metres?

Thanks

It is the distance calculated using "Great Circle Distance". Basically the distance between the two locations following an approximation of the Earth's surface. More info:
