The geometric distance correction (geometric ppm) is derived from the map
projection distortion (map projection ppm), the height above reference datum
correction (height ppm) and an individual correction (individual ppm).
The calculation of the map projection ppm follows the formula for the Trans-
versal Mercator Projection. The individual factors are: the scale factor of the line
of projection central meridian, Gauss-Krüger = 1.0, UTM = 0.9996, and so on,
and the offset from the line of projection.
The calculation of the height ppm is derived from the height of the instrument
setup above the reference datum. Normally this is the height above mean sea-
level MSL.
