[SCALE]
Scale of projection.
Scale factor:
Entering the scale of projection. Measured values
and coordinates are corrected with the PPM param-
eter.
[PPM=0]
Sets default parameters.
[PPM]
Input of individual scaling parameters.
[ATMOS]
Input of atmospheric parameters.
Atmospheric Parameters (ppm):
Distance measurement is influenced directly by the
atmospheric conditions of the air in which distance
measurement are taken.
In order to take into consideration these influences
distance measurements are corrected using atmo-
spheric correction parameters.
