The main objective of the project is to develop technology for obtaining and exploring gravimetric data from the coast of Polish marine areas and its coastline. The project aims to harmonise marine altitude measurements with the EVRS system by exploiting the differences in the potential of gravity from the Normaal Amsterdams Peil reference level. This is in line with the guidelines of the Baltic Sea Hydrographic Commission (BSHC) of the International Organisation of the IHO. This solution will concern areas which are of interest to the Polish maritime economy. The scope of research and development work is compatible with KIS 15's task 'bdquo; Intelligent networks and geoinformation technologies’. An important element will be to improve geoid parameters by checking existing gravimetric data and filling empty areas. These activities provide an important basis for safe maritime navigation. The team of Gdańsk University of Technology in cooperation with the team of the Maritime University in Szczecin and GEOPARTNER employees intends to conduct measurements using the MGS-6 gravimetric system of Micro-g LaCoste, LLC. Research vessels of the Academy will be used to perform measurements. These tests will integrate data from lidar, multi-component echo probes and precision navigation devices. It is planned to prepare technologies for exploration of gravimetric data, supported by tools and IT programs. We intend not only to refer to the surface of the earth, but also to use the data in regional geological exploration for the purposes of carding geological structures and studying geodynamic phenomena in the coastal zone. Validation of developed technologies will be an important element during the project. Results of industrial research and experimental development work
