7.1.8 Scale Correction
Use of scale
correction
By entering a scale correction, reductions proportional to distance can be taken
into account.
•
Atmospheric correction.
•
Reduction to mean sea level.
•
Projection distortion.
Atmospheric
correction
D1
The slope distance displayed is correct if the scale correction in ppm, mm/km,
which has been entered corresponds to the atmospheric conditions prevailing
at the time of the measurement.
The atmospheric correction includes:
•
Adjustments for air pressure
•
Air temperature
•
Relative humidity
For highest precision distance measurements, the atmospheric correction
should be determined with an accuracy of 1 ppm. The following parameters
must be redetermined:
•
Air temperature to 1 °C
•
Air pressure to 3 mbar
•
Relative humidity to 20 %
