GEOSS Interoperability Workshop III

October 18, 2011

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

Wizard picks appropriate workflow for desired result

Workflows

Estimated rainfall accumulation and flood prediction model

Flood Model

Selected workflow automatically activates needed assets and models

Baseline water level, flood waters and predicted flooding

Example: EuroGEOSS in GEOSS AIP – Habitat calculation with WPS

Example: Air Quality in AIP-3Visualizing uncertainty in AIR information

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

AIP Evolutionary Development Phases has piloted the GEOSS 10 Year Plan Architecture • AIP-1 

– Kickoff: June 2007– Result: "Core" Architecture defined most of the GCI IOC – Architecture

Workshop – http://www.ogcnetwork.net/pub/ogcnetwork/GEOSS/AI_Pilot_Demo/inde

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

• Improved access to variety of observations

– Remote sensing, in-situ sensing, & models

• Increased capabilities through web services

– Access, Processing, Data, Semantics

• Repeatable results through engineering process

– Scenarios, Services, Interoperability Arrangements

• Improved decision-making

– Coordinated SBA and technical developments

AIP-3 Complete

• GEOSS bold vision endorsed 5 years ago

• Architecture vision now realized for several societal applications
