Marine mapping is all about holistic approach to create picture of seabed: morphology, sedimentology and biology.

Our data is suitable to create and interpret thematic maps of diverse habitats that can be used to implement marine policy, management and resource utilization.

Seafloor mapping and visualisation

Application Monitoring indicators for Marine Strategy Framework Directive (MSFD) descriptors based on precise geolocation:

Biodiversity: distribution and size of seabed habitats, larger species and non-indigenous species, biomass evaluation from 3D model;

Eutrophication and Physical damage effects on seabed and habitats

Seafloor integrity: damage on sea bottom, changes in integrity;

Monitoring of changes in hydrographical conditions;

Marine litter hot spots (surface and sea bottom)

Integrated research of large underwater areas – detailed georeferenced

seafloor mapping.

Implementation of Marine Spatial Planning (MSP) and

Integrated Coastal Zone Management (ICZM).

3D visualization, modeling and projection for research and

dissemination (cultural and natural heritage, virtual “travelling” over

underwater natural or archaeological sites).
