The EMODnet data infrastructure is being constructed in three major phases and is currently in the 3rd phase of development (2017 - 2020). Building on the EMODnet Bathymetry portal developed during Phase I (2009-2013) & Phase 2 (2013-2017), Phase 3 will see further upgrading of the EMODnet Digital Terrain Models (DTM), including incorporation of more surveys and further improvement of the digital bathymetry. Satellite Derived Bathymetry (SDB) data will be included to cover gaps in survey coverage. Coverage of the DTM will be extended to include also the European coastal zones as well as the European Arctic region and Barentz sea. Furthermore, higher resolution DTM will be developed and made available where underlying data are available and released for publication by its owners.
