EMODnet Digital Bathymetry (DTM 2020)
The "EMODnet Digital Bathymetry (DTM)- 2020" is a multilayer bathymetric product for Europe’s sea basins covering:
• the Greater North Sea, including the Kattegat and stretches of water such as Fair Isle, Cromarty, Forth, Forties,Dover, Wight, and Portland
• the English Channel and Celtic Seas
• Western Mediterranean, the Ionian Sea and the Central Mediterranean Sea
• Iberian Coast and Bay of Biscay (Atlantic Ocean)
• Adriatic Sea (Mediterranean)
• Aegean - Levantine Sea (Mediterranean).
• Madeira and Azores (Macaronesia)
• Baltic Sea
• Black Sea
• Norwegian and Icelandic Seas
• Canary Islands (Macaronesia)
• Arctic region and Barentz Sea
The DTM is based upon more than 16360 bathymetric survey data sets and Composite DTMs that have been gathered from 49 data providers from 24 countries riparian to European seas. Also Satellite Derived Bathymetry data products have been included derived from Landsat 8 and Sentinel satellite images. Areas not covered by observations are completed by integrating GEBCO 2020 and IBCAO V4.
The source reference layer in the portal viewing service gives metadata of the data sets used with their data providers; the metadata also acknowledges the data originators. The incorporated survey data sets itself can be discovered and requested for access through the Common Data Index (CDI) data discovery and access service that in December 2020 contained > 30.000 survey data sets from European data providers for global waters. The Composite DTMs can be discovered through the Sextant Catalogue service. Both discovery services make use of SeaDataNet standards and services and have been integrated in the EMODnet Bathymetry web portal (http://www.emodnet-bathymetry.eu).
In addition, the Bathymetry Viewing and Download service of the EMODnet bathymetry portal gives users wide functionality for viewing and downloading the EMODnet digital bathymetry such as:
• water depth (refering to the Lowest Astronomical Tide Datum - LAT) in gridded form on a DTM grid of 1/16 * 1/16 arc minute of longitude and latitude (ca 115 * 115 meters).
• option to view depth parameters of individual DTM cells and references to source data
• option to download DTM in 64 tiles in different formats: ESRI ASCII, XYZ, EMODnet CSV, NetCDF (CF), GeoTiff and SD
• option to visualize the DTM in 3D in the browser without plug-in
• layer with a number of high resolution DTMs for coastal regions
• layer with wrecks from the UKHO Wrecks database.
The EMODnet DTM is also available by means of OGC web services (WMS, WFS, WCS, WMTS), which are specified at the EMODnet Bathymetry portal.
The original datasets themselves are not distributed but described in the metadata services, giving clear information about the background survey data used for the DTM, their access restrictions, originators and distributors and facilitating requests by users to originator.

- Restriction related to intellectual property rights. Exclusive right granted by law for a specified period of time. Not to be used for navigation. The EMODnet DTM is made publicly available for browsing and downloading and can be freely used under the condition that it is acknowledged (see How to cite). However, for use in commercial software such as electronic mapping packages it is advised to contact individual data providers as an arrangement might be required. Each DTM grid cell has a reference to the source data (bathymetric survey via CDI, composite DTM via Sextant, and GEBCO in case of gaps) used for determining the water depth in the DTM grid cell.

The DTM is a grid of 1/16 * 1/16 arc minute of longitude and latitude (ca 115 * 115 meters).
Each grid cell has the following information:
- x,y coordinates
- minimum waterdepth in meters to LAT
- average waterdepth in meters to LAT
- maximum waterdepth in meters to LAT
- standard deviation of waterdepth in meters
- number of values used for interpolation over the grid cell
- interpolation flag : 1 when extrapolated from the neighbouring cells
