Atmospheric corrections
The settings on this panel define the atmospheric ppm and the refraction.
For standard applications, the distance is corrected due to atmospheric influen-
ces. The geometrical correction and the projection distortions are set to 0.00.
Heights are reduced with the standard refraction coefficient.
Refer to the product specific User Manuals for information on calculations.

.
The atmospheric distance corrections are derived from the dry air temperature,
air pressure or elevation above mean sea level MSL, and the relative air humid-
ity or wet bulb temperature.
