  1. EMODNET Preparatory Actions Hydrographic and Seabed Mapping Service Contracts MARE/2008/03 S12.531515 and MARE/2009/07 S12.563144 By Dick M.A. Schaap – Coordinator Brussels - Belgium, 7th February 2012, EMODnet Concertation Meeting

  2. Members of the SeaDataNet consortium together with other organisations from marine science, the hydrographic survey community, and industry: • MARIS – NL (Management, DM and IT expertise) • IFREMER – FR (Research institute) • ATLIS – NL (IT expertise, DM hydrography) • IEO – ES (Research institute) • NERC-NOC – UK (Research institute) • GSI – IE (HO – Ireland) • SHOM – FR (HO – France) • UNEP-GRID Arendal – NO (International Organisation) • OGS – Oceanography department (IT) (Research Institute) • HCMR (GR) (Research Institute) • Plus Data provider agreements with HO’s from Germany, Norway, Denmark, Netherlands and Belgium • Plus Associate partners: ISMAR-CNR –IT, OGS-RIMA – IT, LNEG – PT, UTM-CSIC – ES, NIOZ - NL (Research Institutes) + IHPT – PT (HO) + recently OceanWise (UK) + Israeli Government, Ministry of National Infrastructures(Israel) + negotiations with Lebanon

  3. Progress

  4. Up till today, 7197 survey CDI metadata records from 13 data centres and 114 data originators have been collated and imported into a dedicated EMODnet Hydrography CDI data discovery and access service. This service was launched in May 2010 and has been upgraded over time with extra functionality • These survey data and other gathered composite DTMs have been collated into regional EMODNet DTM’s that are available for viewing and downloading in several formats via the Hydrography Products portal service. • The dedicated EMODnet Hydrography products portal has been launched in May 2010. It sits atop of the central DTM database and interacts with the CDI service and with OGC WMS services • The Hydrography portal has considerably been upgraded and relaunched in June 2011 in response of feedback and comments received.

  7. Viewing service with digital bathymetry and overlay of CDI data sets

  8. Retrieving parameters of an individual grid cell and retrieving CDI metadata of associated prevailing survey

  10. INSPIRE Compliance • The majority of the services and used formats in the EMODNet Hydrography portal are already INSPIRE compliant • Upgrading of CDI to ISO 19139 transport scheme is underway as part of SeaDataNet II project • Use of external vocabularies is allowed. => SeaDataNet Common Vocabularies have been proposed to INSPIRE via SeaDataNet SDIC for various themes => awaiting feedback in March 2012 • The Delivery of bathymetric survey data sets is done in NetCDF (CF). This is not excluded but not yet named in the INSPIRE Elevation specification. => Has been proposed to INSPIRE via SeaDataNet SDIC => awaiting feedback in March 2012 • For the delivery of the DTM tiles present formats are allowed, but it seems recommended to support also the Bathymetric Attributed Grid Object (BAG), IHO S102, once this is mature => explore

  11. Web statistics

  12. A growing number of users that are finding and browsing through the EMODNet Hydrography portal and its CDI Discovery service. Last months we have > 500 visitors per month with an average browsing of 20 to 30 pages • The publicity campaign undertaken via various offshore, oceanography and hydrography portals and online newsletters seems to have effect • Also a growing number of users are finding the Hydrographic Products service and browse the new digital bathymetry layers. Last months we have >200 users per month with an average downloading of ca 250 DTM files per month • Feedback by the online form is limited and if happening, always positive

  13. Survey coverage of the European waters

  14. Objectives : • To compile an overview of multibeam and single beam surveys for Europe’s maritime basins • To assess the coverage of European seas by high resolution multibeam data • Estimating the costs for filling the gaps • Approach: • Using the already gathered CDI metadata records and exploring further their geographic coverage • Questionnaire has been sent out to other potential sources (incl industry) to identify additional surveys and their coverage • Calculate coverage and assess gaps

  15. Identified multibeam bathymetry coverage around Europe

  16. Percentages of EEZs unmapped by multibeam. part Norway EEZ 82% (305,575 sq km) UK EEZ 75% (566,120 sq km) Ireland EEZ 18% (76,876 sq km)

  17. Coastal zone is missing/not well covered in most part of the gathered data sets and produced DTM • Possible solutions in next tender: • Applying a consistent hierarchy of resolution and a common mechanism of gridding to produce compatible grids allowing generalization without to recompute the DTM each time there a new scale specified which is relevant for the coastal zones • Upgrading the gridding algorithm (also learning from Geo-Seas WP11 experiences) for less anomalies – apply for all regions • Also prepare a fully smoothed (polished) version • Also provide a projected grid (X,Y squares) next to the geographic grid (lat-lon boxes) to serve different user communities • Provide technical support and staff capacity to HO’s for reworking / harmonisation of their DTMs and production of metadata (see North Sea HO’s)

  18. Coming activities

  19. Gather more data sets (surveys and composite DTMs) • Continue with trying to get hold of surveys for composite DTMs of HO’s • Finalise and integrate the Catalogue service for composite DTMs • Together with Geo-Seas project a new freely downloadable 3D viewer is being finalised that will allow users to import the DTM files (NetCDF) and combine these with WMS services (eg geology surface layer) for 3D visualisations and analyses • Produce upgraded release of the new DTMs in June 2012 • Deeper analysis of geographical coverage of European seas by multibeam surveys and gaps analysis • Demonstrate facilities for external loading of users own DTM data
