This document has links to all web services that allow you to search, visualise and download EMODnet data and data products.
The majority of EMODnet web services are Open Geospatial Consortium (OGC) web services, following international standards for geospatial metadata retrieval, visualisation and data access. The image below provides an overview of the different OGC web services offered by EMODnet.
Tuturials on using EMODnet's OGC services in following programming languages are available:
The EMODnet central catalogue offers a Catalogues Service for the Web (CSW) endpoint (see table below), a widely used OGC standard to search collections of metadata for data, services and related information objects and export the metadata in a range of formats. It supports three main HTTP requests (operations), which are submitted in the form of a URL.
| Thematic | CSW GetCapabilities |
|---|---|
| Central Catalogue | https://emodnet.ec.europa.eu/geonetwork/emodnet/eng/csw?service=CSW&request=GetCapabilities&VERSION=2.0.2 |
The GetCapabilities request allows CSW clients to retrieve service metadata from a server. The response to a GetCapabilities request shall be an XML document containing service metadata about the server. This subclause specifies the XML document that a CSW server shall return to describe its capabilities.
The GetRecords request allows to query and filter the catalogue metadata records.
Example: Return a summary of the metadata records in the EMODnet catalogue that contain the word temperature in any of it's metadata fields as specified in the
constraintsparameter (differnt types of filter languages are available, see the GetCapabilities of the service for more information), and then limited to only 10 records for the purpose of this example using themaxrecordsparameter:
https://emodnet.ec.europa.eu/geonetwork/emodnet/eng/csw?
request=GetRecords&
service=CSW&
version=2.0.2&
elementSetName=summary&

      </ogc:PropertyIsEqualTo>
   </ogc:Filter>&

typenames=csw:record&
maxrecords=10
The GetRecordById request retrieves catalogue metadata records using their identifier.
Example: return a record of Temperature in the Water Column (1960 - 2023) - CORA dataset
https://emodnet.ec.europa.eu/geonetwork/emodnet/eng/csw?
service=CSW&
version=2.0.2&

The Web Map Service standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a Geographic Information System (GIS) or in your own web application (OpenLayers, Leaflet,...).
The WMS supports the GetCapabilities, GetMap and GetFeatureInfo operations as defined in the Open Geospatial Consortium (OGC) WMS standard.
The EMODnet WMS services are accessible from 7 thematics at the Pan-European scale or global scale for some specific data products. Enter one of the following WMS endpoint URLs into your WMS client (QGIS, ArcMap, MapInfo etc.):
The GetCapabilities request allows WMS clients to retrieve service metadata from a server. The response to a GetCapabilities request shall be an XML document containing metadata of the service (available layers, associated projections, styles, author ...).
The standard to construct a WMS GetCapabilities request is as follows:
https://ows.emodnet-bathymetry.eu/wms?
service=WMS&
version=1.3.0&
request=GetCapabilities
Using the information given in the GetCapabilities request, the GetMap request returns a raster map containing the requested data layer selected from all the available layers as defined in the XML document. The elements such as the data layer, region, projection, size of the returned image, image format, etc. are defined in the form of arguments.
Example of a GetMap request that returns an image of the EMODnet Bathymetry Mean depth (DTM) based on source resolution of 1/8 arc minute (~250 meter) in multi colour style:
https://ows.emodnet-bathymetry.eu/wms?
service=WMS&
request=GetMap&
version=1.1.1&
layers=emodnet:mean_multicolour&
styles=&
format=image/png&
transparent=true&
info_format=text/html&
tiled=false&
width=400&
height=628&
srs=EPSG:3857&
bbox=-2669794,2250306,4800533,14538934
Which returns:
In contrast to a WMS service, which offers real time rendered georeferenced images for a custom geographic extent, a Web Map Tile Service (WMTS) serves pre-rendered georeferenced map tiles with a fixed geographic extent for different zoom levels. As images are pre-rendered and can be cached (locally or remotely), WMTS offers a superior performance for web map viewer applications.
The EMODnet WMTS service are accessible from following endpoints:
The EMODnet data layers are available as a Web Feature Service (WFS) or Web Coverage Service (WCS) in accordance with the Open Geospatial Consortium (OGC) specifications (www.opengeospatial.org).
Web Feature Service (WFS) defines a standard for exchanging vector data by querying both the data structure and the source data. The basic operations are GetCapabilities, DescribeFeatureType, and GetFeature.
The EMODnet WFS services are accessible from following endpoints:
The GetCapabilities request generates a metadata document (xml) describing a WFS service provided by server as well as valid WFS operations and parameters (available features, supported file formats, etc.).
The standard to construct a WFS GetCapabilities request is as follows:
https://ows.emodnet-bathymetry.eu/wfs?
SERVICE=WFS&
REQUEST=GetCapabilities&
VERSION=2.0.0
A DescribeFeature request returns a description of a feature type (including available attribute fields).
Example of a EMODnet Biology DescribeFeature request:
https://geo.vliz.be/geoserver/Dataportal/wfs?
service=wfs&
version=2.0.0&
request=DescribeFeatureType&
typeName=Dataportal:eurobis&
outputFormat=application/json
Example of a EMODnet Human Activities DescribeFeature request:
https://ows.emodnet-humanactivities.eu/wfs?
service=WFS&
version=1.1.0&
request=describeFeatureType&
typeName=shellfish&
bbox=-1.3,0.3,49.2,49.9
The GetFeature request returns a selection of features from a data source including geometry and attribute values.
Example of a EMODnet Human Activities GetFeature request:
https://ows.emodnet-humanactivities.eu/wfs?
service=WFS&
version=1.1.0&
request=getFeature&
typeName=shellfish&
bbox=-1.3,0.3,49.2,49.9&
outputFormat=application/json
EMODnetWFS is an R package developed to access WFS data from EMODnet. You can install with:
remotes::install_github("EMODnet/EMODnetWFS")Web Coverage Service (WCS) is a data-access protocol that defines and enables the web-based retrieval of multi-dimensional raster type geospatial datasets. The basic operations (HTTP requests) are GetCapabilities, DescribeCoverage, and GetCoverage.
The EMODnet thematics provide Web Coverage Services (WCS) to support requests for coverage data (rasters) or gridded data products. Enter one of the following addresses into your WCS client:
| Thematic | Description | WCS GetCapabilities |
|---|---|---|
| Bathymetry | Data Products | https://ows.emodnet-bathymetry.eu/wcs?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=2.0.1 |
| Biology | Data Products | https://geo.vliz.be/geoserver/Emodnetbio/wcs?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=2.0.1 |
| Biology | New Data Products | https://ows.emodnet.eu/geoserver/biology/ows?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=2.0.1 |
| Human Activities | Data and Data Products | https://ows.emodnet-humanactivities.eu/wcs?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=2.0.1 |
| Seabed Habitats | Individual habitat map and model datasets | https://ows.emodnet-seabedhabitats.eu/geoserver/emodnet_open_maplibrary/wcs?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=2.0.1 |
A WCS GetCapabilities request returns an XML document with information to the service and data provider and an overview of all the coverages (raster dataset) available on the web serveras well as valid WCS operations and parameters.
The standard to construct a WFS GetCapabilities request is as follows:
https://ows.emodnet-bathymetry.eu/wcs?
service=WCS&
request=GetCapabilities&
version=2.0.1
A WCS DescribeCoverage request returns an XML document with metadata information fully describing one specific coverage
Example of an EMODnet Bathymetry DescribeCoverage request:
https://ows.emodnet-bathymetry.eu/wcs?
service=wcs&
version=1.0.0&
request=DescribeCoverage&
coverage=emodnet:mean
A WCS GetCoverage request returns a coverage encoded in a specified format (e.g GeoTiff, ESRI ASCII or netCDF), resampling algorithm, projection, etc.
Example of an EMODnet Bathymetry GetCoverage request:
https://ows.emodnet-bathymetry.eu/wcs?
service=wcs&version=1.0.0&
request=getcoverage&
coverage=emodnet:mean&
crs=EPSG:4326&

format=image/tiff&
interpolation=nearest&
resx=0.00208333&
resy=0.00208333
Some thematics provide other, non-OGC, download services that are more suited for the types of data they offer. This includes ERDDAP & THREDDS services for the retrieval of multidimensional raster data using the OPeNDAP standard and a custom REST API service to extract the water depth at locations and along profiles from the EMODnet Bathymetry Digital Terrain Model.
