EMODnet Digital Bathymetry (DTM 2016) - Tile D3

The "EMODnet Digital Bathymetry (DTM) - 2016" 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 and Central Mediterranean Sea and Ionian Sea

• Bay of Biscay, Iberian coast and North-East Atlantic

• Adriatic Sea

• Aegean - Levantine Sea (Eastern Mediterranean)

• Azores - Madeira EEZ

• Canary Islands

• Baltic Sea

• Black Sea

• Norwegian – Icelandic seas



The DTM is based upon more than 7700 bathymetric survey data sets and Composite DTMs that have been gathered from 27 data providers from 18 European countries and involving 169 data originators. The gathered survey data sets can be discovered and requested for access through the Common Data Index (CDI) data discovery and access service that also contains additional European survey data sets for global waters. This discovery service makes use of SeaDataNet standards and services and have been integrated in the EMODnet portal ( https://emodnet.ec.europa.eu/en/bathymetry#bathymetry-services ). The Composite DTMs are described using the Sextant Catalogue Service that makes also use of SeaDataNet standards and services. Their metadata can retrieved through interrogating the Source Reference map in the Central Map Viewing service ( https://emodnet.ec.europa.eu/geoviewer/ ).

In addition, the EMODnet Map Viewer 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 1/8 * 1/8 arc minute of longitude and latitude (ca 230 * 230 meters)

• option to view depth parameters of individual DTM cells and references to source data

• option to download DTM in 16 tiles in different formats: EMO, EMO (without GEBCO data), ESRI ASCII, ESRI ASCII Mean Sea Level, XYZ, NetCDF (CF), RGB GeoTiff and SD

• layer with a number of high resolution DTMs for coastal regions

• layer with wrecks from the UKHO Wrecks database.

The NetCDF (CF) DTM files are fit for use in a special 3D Viewer software package which is based on the existing open source NASA World Wind JSK application. It has been developed in the frame of the EU FP7 Geo-Seas project (another sibling of SeaDataNet for marine geological and geophysical data) and is freely available. The 3D viewer also supports the ingestion of WMS overlay maps. The SD files can also be used for 3D viewing by means of the freely available iView4De(Fledermaus) software.



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.

Statement

The DTM is a grid of 1/8 * 1/8 arc minute of longitude and latitude (ca 230 * 230 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

- average waterdepth smoothed by means of a spline function in meters to LAT

- an indicator of the offsets between the average and smoothed waterdepth as a % of the waterdepth

- reference to the prevailing source of data with metadata.



Source data :

The DTM values have been determined from 3 possible sources of data:



- Bathymetric surveys : More than 14000 high resolution data sets from single and multibeam surveys, managed by 27 data centres from 18 countries and originated from 169 institutes, as referenced via the CDI Data Discovery and Access service.

- Digital Terrain Model data : 78 composite data sets produced and delivered by a number of external data providers such as Hydrographic Offices derived from their internal bathymetric database and based upon historic surveys. These are referenced via the Sextant Catalogue service

- GEBCO 2014 30” gridded data, used to complete area coverage in case there are no survey data or composite data sets available to the partners.



From these a subset has been used as input for analysing and generating the EMODnet digital terrain model (DTM).



No new data has or will be collected specifically for this project.



GEBCO (General Bathymetric Chart of the Oceans) is partner in the project and not only provides the latest GEBCO releases for filling gaps but also uses the EMODnet DTM for upgrading the GEBCO DTM for the Baltic Sea synergy takes place with the Baltic Sea Bathymetry Database project of the Baltic Sea Hydrographic Commission.



Additionnal QA/QC and DTM production details are available on the EMODnet Bathymetry portal.
