New version of European Bathymetry Digital Terrain Model

By Eric Van Rees - 27th January 2021 - 08:34

The European Marine Observation and Data Network (EMODnet) High Resolution Seabed Mapping Project, which has been running since 2009, has released an update of its Digital Terrain Model (DTM), which now includes greater coverage across European Seas and beyond.

The EMODnet Bathymetry portal aims to provide a single access point to bathymetric products, Digital Terrain Models (DTM) and data (survey data sets and composite DTM).

OceanWise is a full partner in EMODnet and is proud to lead the UK contribution on this auspicious project. OceanWise’s role is to process large volumes of sometimes overlapping hydrographic survey data from a variety of sources and to create a seamless seabed or bathymetric surface, or DTM, of the whole of the UK Continental Shelf. A high-resolution version of the DTM is included in the OceanWise Marine Themes Marine Mapping data product and Web Map Tile Services (WMTS), while a sub-sampled lower resolution version is submitted to EMODnet for inclusion in the European Seas DTM which then also contributes to GEBCO and the Seabed 2030 project. Other partners in EMODnet adopt a similar approach. As well as the DTM, OceanWise processes and corrects large volumes of metadata and outputs this in a format compatible with the SeaDataNet project. The metadata is linked to the DTM, so the source or provenance of the data is always apparent and maintained.
