The baseline in Poland runs at a depth of approximately 1 m, so a special methodology is required for its measurement. The results of our analyses showed that using an unmanned vessel, on which a multi-GNSS receiver and a miniature MBES or SBES can be installed, is currently the optimum and the most effective method for determining the territorial sea baseline.ДЄnother important issue is the methodology used to perform hydrographic measurements, which enables baseline determination. It presents a method for planning a hydrographic survey using both manned and unmanned vessels and presents oceanographic parameters that should be determined before and during hydrographic measurements, as well as a method of choosing the measuring equipment used in bathymetric measurements in ultra-shallow waters.

This paper discusses an effective and optimal method of performing bathymetric measurements to enable territorial sea baseline determination in selected waterbodies of Poland. For Poland, as well as in other coastal states, baseline determination can be considered from both a legal and measurement-related point of view. Baselines are used to establish the maritime boundaries of a coastal state which include the territorial sea, contiguous zone, exclusive economic zone and continental shelf thus, they are instrumental in implementing state maritime policy.
