C1.2.2. Data and information requirements for MSP

Lead partner: Service Hydrographique et Océanographique de la Marine

Specific Objective: To support access to and use of maritime spatial data.

data-gather-crown-copyrightwater-sampling-crown-copyrightA key element of MSP is high quality maritime spatial data and information, and the infrastructure to support its exchange and use.

This action will examine the data and information requirements for MSP, specifically the challenges around transboundary working, and will also look at existing infrastructure arrangements and how these might be optimised.

  • Begin to address gaps such as a lack of data, or data that might not be publicly available;
  • Establish a link with complementary MSP data initiatives to provide guidance for future interaction;
    Investigate the steps needed to make MSDIs interoperable to enable the display of transboundary information such as base lines, maritime boundaries, regulated areas and maritime activities;
  • Assessment of data semantics and their implications for MSP e.g. different interpretation of chart datum. Linking with other relevant projects e.g. COVADIS – whose role is to standardize most frequently used geographical data and the requirements of the INSPIRE Directive. An exercise to harmonize metadata will also be undertaken;
  • Consider a decision support tool which could enable planners to take into account several activities, possible constraints and scenarios when implementing MSP;
  • Organize a training workshop to help stakeholders become familiar with the spatial analysis functions developed within data.shom.fr Progress with regard to interoperability may allow users to transfer this knowledge into their portals and existing data centres;

SIMCelt data portal demonstrator

The SIMCelt data portal demonstrator is a tool with a primary objective to support the study Analysis of Data Needs and Existing Gaps. Issues are most often encountered when displaying and disseminating relevant Maritime Spatial Planning data on either side of a maritime boundary. Data and information analysis is facilitated by the existence of the portal, which allows testing of compatibility between different data sets and uncovers issues such as differing scales, symbology or missing data.

Its secondary objective is to address the needs and gaps discovered during the project by publishing relevant MSP data on the Celtic Seas alongside a metadata catalogue.

This Marine Spatial Data Infrastructure is an important contribution to overcoming data incompatibility issues, helping to build a shared knowledge for stakeholders particularly in a transboundary area. The portal demonstrator also features a map viewer to enable users to visualise the data and will provide a thematic digital atlas of pre-loaded maps to display data, for example, on specific human activities in areas. The portal is still under development, and should be available from September 2017.


  • Analysis of data needs and existing data gaps; specifically relating to transboundary working.
  • Assessment of opportunities and barriers to interoperability and suggested action plan to address data needs and improve data exchange.
  • Initial activity to address data needs
  • Data management guidance document.
  • Enhancement of relevant information tools, particularly to enable interoperability, and ability to produce Celtic Seas wide information.
