Distance Correction

This operator is used to correct distance variables. You can specify the settings for distance Offset and Scaling. The following algorithm is used to calculate corrected distance data:

Corrected Distance data = Offset + Scaling * Uncorrected Distance data

Echoview accepts Distance data as input.
