Multibeam Echo Sounder Systems (MBES) shallow water surveys provide capability not
only acquiring bathymetric data useful for determining isobaths and mapping features on the
seafloor which may be a hazard to navigation. They also allow detection of objects smaller or
deeper than those required for the safety of seafaring and International Hydrography Organization (IHO) standards. In this article some of issues related to of efficient MBES shallow
water surveys are stressed. Additionally a draft of post-processing techniques and result data
format together with tools allowing extraction of bottom object from bathymetric data are presented.
