Scale factor due to height - MDT25

28.21 Scale factor due to height

This is a correction due to height which to some extent affects the distance measured.

Generally speaking, this correction is minimal, but it must not be ignored as for altitudes of 700 meters it attains quite large values, particularly worthy of consideration when measurements are taken with electronic distance measurement capable of measuring distances in kilometers with very few centimeters of error.

It will be enabled by default as it is worth using it in any case.

where:

Rt = Radius of the Earth. By default 6370000.

h = ellipsoidal height.

The Radius of the Earth may be modified under configuration.
