Reference points
The EM 122 is a precision instrument for bathymetric swath mapping. To be able to
produce data that are both detailed and correct, it is necessary to calibrate the survey
vessel very well, and perhaps better than what may have been standard practice earlier.
The required calibration consists of:
• measurement of where sensors and transducers are located
• measurement of how sensors and transducers are oriented
• measurement of the water line vertical location
• alignment of angular measurement sensors
• determination of any offsets in sensor data
• determination of any time delays in sensor data
