Part of the vision: an INSPIREdSeaDataNet

National Data Centres

Step one: What’s the marine data like?• Analyse SeaDataNet source data of two SeaDataNet data 

providers

Ocean Data View (ODV) ASCII file

INSPIRE Conference 2018 

Measurements on several variables from 24 locations during one cruise

Variables measured corrsponding BODC P01 code list

Links between each measurement and metadata (CDI)

sdn‐userdesk@seadatanet.org – www.seadatanet.org

Common Data Index (CDI) metadata

Cruise Summary Report (CSR) metadata

7

INSPIRE Conference 2018, 

Cruise Summary Reports (CSR) are the usual means for reporting on research vessel cruises

sdn‐userdesk@seadatanet.org – www.seadatanet.org

Step two: Which INSPIRE themes are relevant?

• Introduce relevant INSPIRE themes of relevance to the SeaDataNet community– Environmental Monitoring Facilities, EF

• The platform, activity and network collectingmarine measurements

– Oceanograhic Geographic Features, OF• O&M Specialised Observation types to use

for provision of marine data in INSPIRE

– INSPIRE Observations & Measurements(O&M) data model of GCM

Step three: How to map and encode?• Do a proof‐of‐concept mapping from SeaDataNet data sources

to a selection of INSPIRE application schemas

10

INSPIRE Conference 2018

sdn‐userdesk@seadatanet.org – www.seadatanet.org

Matching tables and GMLs• Environmental Monitoring Facilities (EF):

– EMF: Platform and EMA: Activity– EMF: Sampling Point

• EF/OF– Feature of Interest– Process

• Oceanographic Geogrpahic Features (OF):– OF/Specialised Observations: Time Series– OF/Specialised Observations: Profile – OF/Specialised Observations: Trajectory

11

INSPIRE Conference  2018, 

Examples have been published at the INSPIRE Thematic Cluster for feedback and re-use

sdn‐userdesk@seadatanet.org – www.seadatanet.org

Step four: Open issues?• Document the work and report issues

Feedback to SeaDataNet (SDN), eg:– Data (ODV) and metadata (CDI+CSR) 

needed in mapping– Insufficent Process informatin in SDN– Need to set up namespace strategy– Need for validation and feedback on the 

encoding– Need to take decisions on provision

12

INSPIRE Conference  2018 

sdn‐userdesk@seadatanet.org – www.seadatanet.org

Five, six, seven…: Things to change?• Feedback to INSPIRE

– Request to provide change requests on behalf of SDN and the marinecommunity• Request to support WGS84 as this is not a default CRS in INSPIRE• Errors and inconsistencies found in TrajectoryObservation• Lack of guidance for out‐of‐band encoding in the INSPIRE documents

– Kathi Schleidt, Facilitator of the Environmental Monitoring and Observations Thematic Cluster • Issues related to the provision of Coverages and ProfileObservation(pressure= depth) has been brought forward 13
