Quality analysis of a collected depth dataset is important in order to find the statistic accuracy
and variance of the depth data. Any systematic errors have to be identified and if possible
minimised. It is also important to establish if the data fulfils the accuracy standard stated in the
survey specification.
The accuracy of collected depth data depends on several parameters such as the accuracy of the
sensors in the survey system, the accuracy of the sensor calibration and the accuracy of any
additional reductions to the dataset.
