Primary geological survey information requires significant expert interpretation to generate user-friendly maps. Geological data are often used in combination with bathymetry to build up a comprehensive picture of the seabed and its subsurface. These data are a vital component of seafloor habitat maps and are essential tools in marine spatial planning, coastline protection, offshore installation design, environmental conservation, risk management and resource mapping.


Objectives of EMODnet Geology

The geology portal provides free access to (i) geological data and metadata held by various geoscience organisations in Europe, delivered in accordance with international standards, and (ii) geological data products compiled at scales of 1:1,000,000, 1:250,000 and 1:100,000 or finer where the underlying data permit.


Key services provided by EMODnet Geology

EMODnet Geology portal provides a range of services and functionalities to users for viewing and downloading geology data and products. Currently, the following key services are provided:

  1. Data Discovery and Access Service: provides functionality to access data, produced by the EMODnet Geology project and made available via WMS (Web Map Service) and WFS (Web Feature Service) with an associated metadata record.
  2. Composite Products Discovery and Access Service: provides functionality to search the catalogue for maps and other geographic data according to specific search criteria.
  3. Viewing and Download Service: provides functionality to search and download records according to specific search criteria. Each result links to a full metadata record.


  1. Data Discovery and Access Service

See the online services available here:

The EMODnet Geology portal provides access to information and services produced by the EMODnet Geology project and is powered by GeoNetwork ( open-source software. This is a catalogue application to manage spatially referenced resources based on the principles of Free and Open Source Software (FOSS) and International and Open Standards for services and protocols (a.o. from ISO/TC211 and OGC). Data within the portal are made online available via GeoServer ( as WFS (Web Feature Service) and WMS (Web Map Service). These services are powered by EGDI (European Geological Data Infrastructure) on the Europe Geology portal (

  • search for WMS services of interest;
  • view information on the service;
  • view and interact with the service via a map interface;
  • obtain a link to the service to incorporate into a desktop GIS or other mapping application.
  1. Composite Products Discovery and Access Service

There are many different ways to search the catalogue for maps and other geographic data. The most common way is via the catalogue or the search bar. The search bar allows you to enter a free text term and also offers a list of options depending on the text entered. The results of your search will be displayed on a catalogue page, with the option to add additional search options such as:

  • Searches based on data content such as keywords, organisations who have data available or the type of information being searched for.
  • Spatially defined searches based on spatial extent selected on the map interface.

The simplest way to find data of interest is to use the data catalogue and filter data using a list of options provided as a querying aide.

  1. Viewing and Download Service

See the products available for download here:

Each product can be viewed as WMS example or on map prior to downloading.


Geological information is being compiled from a variety of sources, but principally from the national geological survey organisations of Europe. Harmonisation of national information is based on the principles established during the ur-EMODnet Geology Project (2009-2013). In addition to seabed-sediment information, EMODnet Geology has also been compiling information on the Quaternary geology of the seafloor (sediments deposited during the last 2.5 million years).

The EMODnet Geology portal provides access to project information and services. Data are made available via WMS with an associated metadata record. Links to the WMS can be used to incorporate information into a desktop GIS or other mapping application. The catalogue of available information can be searched either by listing information layers or by displaying the information on a map.

Data sources

Geological data from Europe’s seas are collected by national organisations using a range of tools and techniques. The main providers of data for EMODnet Geology are the national geological surveys, but other entities hold and contribute data.

The project also develops links with other initiatives and organisations collecting and holding relevant data and information. By making use of such third-party sources of information, the project ensures that there is no duplication of effort and that the users of the EMODnet Geology portal can be confident of sourcing the best and most up-to-date information available.


EMODnet Geology product development

EMODnet Geology data and map products contain information on the seabed substrate, including rate of accumulation of recent sediments, the seafloor geology (bedrock and Quaternary geology), coastline behaviour, geological events and probabilities, mineral resources, and submerged landscapes.

All interpretative products are based on primary information owned by the project partners, supplemented with other information in the public domain. Where the most up-to-date geological information is held on third-party websites, arrangements have been made for WMSs to provide these data to the EMODnet Geology portal.


Improvements in the current development Phase IV (2019-2021)

In addition to the seas included during earlier EMODnet phases (2009-2016), the partners in the consortium are expanding the geographical scope of the work programme to include also the Caspian Sea.

Improvements in the current development phase include updated GIS layers of seabed substrate information at a scale of 1:100 000 or more detailed from the European Seas, including Caspian Sea. In addition multi-scale map(s) will be developed further using all available seabed substrate information at different scales (e.g. 1: 25 000).
