France's Naval Oceanographic and Hydrographic Service (SHOM) is studying automatic algorithms to detect dubious soundings which reduces the cost of the data cleaning. Three algorithms were developed by the Centre de Geostatistique-Ecole des Mines de Paris based on geostatistical techniques. These algorithms were integrated into the data-cleaning system developed at SHOM. The raw data set is first processed by the detection algorithms then the operator controls the detected data. The first tests on board show a dramatic reduction in the processing time with an increase in quality.
