GEOSS Interoperability Arrangements
- From the GEOSS 10 Year Plan Reference Document -
• Interoperability through open interfaces
– Interoperability specifications agreed to among contributing
systems
– Access to data and information through service interfaces
• Open standards and intellectual property rights
– GEOSS adopting standards; agreed upon by consensus,
preference to formal international standards
– GEOSS will not require commercial or proprietary standards
– Multiple software implementations compliant with the open
standards should exist
– Goal is that at least one of the implementations should be
available to all implementers "royalty-free"
GEO Task AR-09-01b
Architecture Implementation Pilot
• Support SBAs by developing new process
and infrastructure components for GCI and
the broader GEOSS architecture
• Evolutionary Development thru AIP Phases
• Demonstrate and document results to inform
GEOSS Development progress
“fostering interoperability arrangements
and common practices for GEOSS”
AIP-3 Focus Areas
• SBAs addressed
– Energy
– Disaster Management
– Climate Change and
Biodiversity
– Water Drought
– Health: Air Quality
• Technology Areas

Data Harmonization
Data Sharing
Semantics
AIP Interaction with Users
• User scenarios drive development
– Implemented through use cases
– Scenario WG interaction with CoPs
– Scenario demonstrations recorded for later se
• AIP support of UIC Usability Testing
– GCI came from AIP-1
– AIP supported GCI usability testing
– Recommend usability testing for AIP-4 results
• AIP-4 focus on data to users
– Increase access to UIC priority observations
– Usability testing of access enablers
AIP Architecture Elements
• Components
– Manageable units hardware, software, networks
• Services
– Methods for components to interact using GEOSS
Interoperability Arrangements
• Use Cases
– Describe what can be done with Services, e.g.,
Discovery, Access, Workflow, etc.
• Scenarios
– Meet SBA User needs;
accomplished with Use Cases

AIP Use Cases
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.
