SDD Experts Survey and Analysis
4
Introduction

• The Experts Survey and Analysis provides a
  survey and analysis of organisations, projects
  and key personnel who hold suitable knowledge and
  expertise and could be approached to support the
  work of this project.

5
Experts

• Satellite Observing Systems (SOS)
• great expertise in all aspects of satellite
  remote sensing of the marine environment
• The European Union Satellite Centre (EUSC)
• Agency of the Council of the European Union
  dedicated to the exploitation and production of
  information derived primarily from the analysis
  of earth observation space imagery
• The European Environment Agency (EEA)
• The European Environment Agency is the EU body
  dedicated to providing sound, independent
  information on the environment
• Integrated Coastal Zone Management (ICZM)
• Integrated planning and management of coastal
  resources and environments in a manner that is
  based on the physical, socioeconomic, and
  political interconnections both within and among
  the dynamic coastal systems, which when
  aggregated together define a coastal zone.

6
Experts

• The Environmental Knowledge Organisation
  Laboratory GEMET THESAURUS
• Activities related to the construction and
  maintenance of mono- and multilingual thesauri,
  classification schemes and terminological systems
  for the environment.
• The Laboratory of Applied Ontology (LOA) DOLCE
  ONTOLOGY
• Performs basic and applied research on the
  ontological foundations of conceptual modeling,
  exploring the role of ontologies and ontology
  management
• Marine Metadata Interoperability Initiative (MMI)
• International cooperative project working to
  promote the exchange, integration and use of
  marine data though enhanced data publishing,
  documentation and accessibility.
• MULTH-TU/Chemnitz - MULTH , Multi-Lingual
  Thesaurus for Risk Management
• This project develops a multilingual hypertext
  glossary of risk with integrated computer-aided
  learning facilities.

7
Experts

• Exprivia - DeepKnowledge
• Dedicated to the acquisition, organisation and
  exploitation of know-how found in information
  sources, interpreting them in their context,
  identifying every possible causal relationship
  between them and classifying them according to
  their interpretation
• SeaDataNet
• Dedicated to construct a standardized system for
  managing the large and diverse data sets
  collected by the oceanographic fleets and the new
  automatic observation systems.

SDD Application Analysis
10
Introduction

• The Applications Analysis
• Focuses on applications, on the systems that
  have been assembled to provide the infrastructure
  and the supply chain necessary to deliver the
  services.
• Objectives
• 1. Select 10 distinct application domains
• for a detailed analysis, and then from this
  analysis
• 2. Select 5 applications
• Related to different aspects of marine
  activities
• Need different classifications
• Well suited to form the basis of a test service
  developed for SDD

11
Desired Application Characteristics

• Mature, operational, and of demonstrated interest
  to users.
• Sufficient information on application to support
  development of an ontology based tool.
• SDD tool will create added value for users.
• Good match to MSU applications
• Marine Applications
• European relevance and interest

12
Applications considered

• The ESA GMES Service Element Fast Track
  Services
• Particularly MARCOAST,but also note Risk EOS and
  Land Mapping
• Also note GMES COASTWATCH ICZM service
• The ESA Data User Envelope programme
• The Earth Observation Market Development
  programme
• The EC Framework 6 programme.
• InterRisk, MERSEA
• These were matched against potential
  applications selected by experts from Mississippi
  State University, for which they had already
  carried out some initial semantic developments.

13
Observations on MARCOAST

• Effectively only 3 DISTINCT service lines
• Oil Spill Monitoring (S1, S2)
• Water Quality / Algal Blooms (S3, S4, S5)
• Ocean State and Dynamics (Met-Ocean) (S6)
• Hence the need to consider services from other
  projects

14
Initially considered Applications
European MSU
15
Finally Selected 10 Applications for analysis

• Near Real Time wind wave information / Storm
  Surges
• Ocean State Monitoring
• Coastline Mapping Wetland Estuary Erosion
• Fisheries Support Services / Fisheries Monitoring
• Water Quality Monitoring / Sediments and
  Pollutants
• Oil Spill Monitoring
• Ship Monitoring / Vessel Traffic Management
• Flood Monitoring, Flood Hazards Monitoring
• Watershed monitoring for sediments and pollutants
• Land Use / Land Cover in Coastal Zones

16
Applications Analysis - sources of information

• MARCOAST
• Service Prospectus
• Interviews with service providers
• Questionnaires
• InterRisk
• Phone and face to face discussions
• Other GMES, ESA (EOMD, DUE) and EC (FP6)
• Internet search and service documentation
• MSU
• Telecon and provided documentation
• NOAA
• Internet Search and service documentation

17
Applications Analysis - required information

• Project ID
• Geographical Coverage
• Technology platform (for service delivery)
• Technology platform (for semantic development)
• EO data sources
• Other data sources
• Significance of user interest
• ESA / MSU match
• Potential for EOSDD

Criteria to assess the relevance of candidate
EO-Applications

• The final ranking weight function is based on
• where
• m is the experience or maturity and number of
  the existing providers,
• i is the strategic interest from the EU in them,
• c is the closeness of the match of the EU
  application with the MSU application
• a is the potential of adding (SDD) value to the
  application through this project and
• d is the relation with marine-domain applications
  (Mediterranean mainly).
