WP6: Technical update EMODnet biological portal & link with other portals

Leader: Flanders Marine Institute (VLIZ)
MARIS, ULg

Objectives

The objectives of WP6 are to develop and maintain the EMODnet biological portal and portal services and to make the data, metadata and data products that are created and mobilized during the project available through the biological portal. The data, metadata and data products available from the portal will also be made available through the EMODnet central entry-point portal and the portal will be fine-tuned to ensure convergence with the other EMODnet portals and to connect to remote databases and data systems. The EMODnet portal will be maintained throughout the duration of the project and the users, usability and effectiveness of the portal will be monitored.

Activities

We will build further upon the data portal that was developed during the pilot project of EMODnet biology. A set of new functionalities will be included, meeting the requirements described in this tender and discussed in detail under the portal components. The portal will give access to different data, metadata and data products and, depending on the database system and database technology used, different possibilities of linking with the EMODnet portal will be set up to provide access to different data and metadata.

Links and interoperability of the EMODnet Biology portal

  • A technical update will enable the portal system to harvest data that is described by Common Data Index (CDI) in the SeaDataNet infrastructure.
  • Geospatial data can be made accessible through the EMODnet biological portal through several OGC Webservices. Besides the Catalogue Service of the Web (CSW) which will enable access to metadata resources, three other OGC Webservices will be implemented:
    1. Web Feature Service (WFS). This service allows requests for geographic features across the Web. As such, the vector data on the portal can be transferred using this service.
    2. Web Coverage Service (WCS). This service allows requests for gridded data across the web. As such, raster data of the portal can be transferred using this service.
    3. Web Map Service (WMS). This service allows requests for maps across the web. As such, GIS maps of the portal can be transferred using this service.
  • Species occurrences data can be made available using the Darwin Core standard that is in use by the Global Biodiversity Information Facility (GBIF) and the Ocean Biogeographic Information System (OBIS).

Development of the portal: Portal components

The biological data portal will build further on the biological data portal developed under the EMODnet biology data portal. This portal visualizes and makes data accessible through a unified search index. Data are available at three different levels of accessibility and precision:

  • metadata of a dataset
  • raw data
  • aggregated data or data products

Search, View and extract data

  • Spatial queries will be made possible by entering exact coordinates, by selecting a region on a geographic map or by selecting standardized sea areas
  • Taxonomic queries can be done at any level of the taxonomic classification
  • Users will also be able to select metadata, data and data products from specific thematic and/or long-term monitoring datasets.
  • The result of the spatial queries will be returned and plotted on a geographical interface, creating GIS layers. By creating multiple queries, the user can superimpose the different GIS layers and compare
  • Selected data, which can be the result from different surveys, can be extracted and downloaded
