Mapping the Depths Uncertainty by Comparison Between Multibeam Regular and Crosscheck Lines

Maps and graphics are useful to approach the total vertical uncertainty and to evaluate the quality of the hydrographic survey. They are created supported by the Standards for Hydrographic Surveys, from International Hydrographic Organization (2008), and according to the analysis of comparison between multibeam regular and crosscheck lines. Complementary, one will be able to identify some biases that were not removed during the sensors’ calibration. The methodology is based on the results of the analysis of two distinct
