Outline
• What are the Architecture Implementation Pilots
(AIP)?
• What is the process followed within AIP?
• What are the major outcomes from the Pilots to-date?
• What are the highlights of the current Pilot AIP-4?
• Where to go for more information?
What are the Architecture
Implementation Pilots (AIP)?
• GEO Task AR-09-01b
• Support SBAs by developing new process
and infrastructure components for GCI and
the broader GEOSS architecture
• Demonstrate and document results to inform
GEOSS Development Baseline progress
“fostering interoperability arrangements
and common practices for GEOSS”

AIP Reusable Process for SBA Integrators
• Scenarios: end user view of the value of GEOSS
– Focused on topics of interest to a community
– Occur in a geographic Area of Interest (AOI)
– Steps in a scenario are mapped to Use Cases
Example: Flood Tasking and Product Generation in AIP-2
Aid levels for disaster relief
funding can be released within
days,
in advance of on-site damage
assessment.
From portal select
desired theme(s) and
area of interest
Selected workflow

AIP Reusable Process for SBA Integrators
• Scenarios: end user view of the value of GEOSS
– Focused on topics of interest to a community
– Occur in a geographic Area of Interest (AOI)
– Steps in a scenario are mapped to Use Cases
• Engineering Use Cases support SBA Scenarios
– Use cases for discovery, data access, etc
– Utilize Standards & Interoperability Arrangements

• Reusable service oriented architecture
– Leverages ‘operational domain value’ through
interoperable services
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.

x.html
AIP-2
– Kickoff: September 2008
– Result: SBA implementations of common cross-cutting architecture
– http://www.ogcnetwork.net/AIP2ERs
– http://www.ogcnetwork.net/pub/ogcnetwork/GEOSS/AIP2/index.html
AIP-3
– Kickoff: March 2010
– Result: Enabled data sharing and network building in GEOSS SBA
communities
– http://www.ogcnetwork.net/pub/ogcnetwork/GEOSS/AIP3/index.html
AIP-3 Summary and Recommendations

endorsed 5 years
ago
• Architecture vision
now realized for
several societal
applications
