AIP-3 Energy Wiring Diagram
Energy Scenario and Use Cases (simplified)
Step Description
Use Case
Policy planner, an Energy Operator and /or Installer of Renewable
Energy System searching for information on environmental impacts
of production of PV electricity on a given area.
Policy planner initiates the environmental impacts assessment.
#4 Search for resources
02
Perform analysis using Solar Radiation and Environmental Impacts
Assessment Web Services
#8 Construct Processing Service
#11 Execute Processing Service
03
Policy planner invokes Client Portlet and selects the relevant
parameters (POI or AOI, PV system, Environmental Impacts
Assessment Method, Azimuth, Inclination Angles) to study PV
electricity production.
#6 interact with services
#7 exploit data visually and
analytically.
04
#1 Visualization Portlet displays results as tabular and graphical
representation of Environmental Impact Indicators for Points Of
Interest
#11 Execute Processing Service
#7 exploit data visually and
analytically.
#2 Visualization Portlet displays results as maps with legends
Reference to the GEOSS Data Providers, datasets, IPR (Intellectual
Properties Rights), data quality, will be provided if appropriate within
the Client Portlets.
#1 Register a resource.
#7 exploit data visually and
analytically.

Additional Technical topics in AIP-3
•
•
•
•
•
Semantics
Web Processing Services
Uncertainty handling
Data Harmonization
Data Sharing Guidelines
Need for CoP Integrator role
Semantics applied to Water in GEOSS
GEO Tasks: Semantics, DIAS, AIP
• Ontology Engineering
• Integration of independent thesauri that are sharing
the same data format, SKOS
• Integrate more general ontologies created with
primitives in schema languages (e.g. SWEET)
• AIP-3 development of an ontology of water-related
terms, based on CUAHSI ontology
– using the CMap2 visual tool.
– OWL ontology for grounding broker's search
Data Sharing in AIP-3
• Primary focus on handling licensing.
– Licensing framework suggested by Harlan Onsrud, et. al.:
“Towards Voluntary Interoperable Open Access Licenses for
GEOSS”
– Framework focused on open access licenses, and used
Creative Commons framework as a working foundation
• Secondary focus on user registration and login.
– Many data sets and repositories require user authentication
prior to data access
– DSGWG looked at single-sign-on (SSO) as a federated
solution and as a centralized solution
The « Data Harmonization » topic
• GEO Task AR-09-01b (AIP)
– Emergence of Data Harmonization topic, pilot and input for
the GEO Task DA-09-01b
– Emphasis on Data Quality and Uncertainty Management
• GEO Task DA-09-01b
– Data, Metadata and Products Harmonization
• Other GEO Tasks (Data Integration, Global Datasets…)
• INSPIRE 2010 Conference and Workshops
– Numerous sessions with Data Harmonization topic
• OGC
– A cross-WG topic : SensorML, O&M, GML, WCS…
– Could be similar to OWS for service interfaces
– Could reach out the Data Quality SWG
GEOSS Information framework
GEOSS SoA Information Viewpoint
AIP-3 Summary and Recommendations
• Improved decision-making
– Coordinated SBA and technical developments
• Improved access to variety of observations
– Remote sensing, in-situ sensing, & models
• Repeatable results through engineering process
– Scenarios, Services, Interoperability Arrangments
• Increased capabilities through web services
– Access, Processing, Data, Semantics
Successful Implementations for SBAs using
GEOSS Interoperability Arrangements
• GEOSS bold vision
endorsed 5 years ago
• Architecture vision now
realized for several
societal applications
• Get involved: GEOSS
