Comparison of Selected Reduction Methods of Bathymetric Data Obtained by Multibeam Echosounder

The publication presents a comparison of various methods to reduce datasets obtained by multibeam echo sounder. Data reduction is the process of minimizing the amount of data that needs to be stored in a data storage environment. Data reduction makes data easier and more effective for the purposes of the analysis. The authors decided to compare selected reduction method used in hydrography: GeoSwath Plus software and BathyDataBASE software. As the scale of the final product was applied 1: 2000. Selected parameters for each of the test methods have been adopted. After reduction of the points surfaces were created. In the next step these surfaces were compared and detailed analysis was conducted.
