Elaboration of GEOSS Architecture

GEO Task AR-09-01bArchitecture Implementation Pilot

• Develop and pilot new process and infrastructure components for the GCI and the broader GEOSS architecture

• Continuation of existing efforts and new activities solicited through AIP Calls for Participation (CFPs) and other means

Slide 3

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"

AIP-2 Achievements

• Community of Practice Scenarios deployed through collaboration with SBA Tasks

• Reusable Process for applying scenarios on Service oriented Architecture – GEOSS SoA

• Contribution/registration of persistent services using GEOSS Interoperability Arrangements

AIP-2 Flood Tasking and Product Generation

Aid levels for disaster relief funding can be released within days, in advance of on-site damage assessment.

CC Impact on Pikasdemonstrated in AIP-2

• This scenario is driven primarily by scientific research on the distribution of pika and how it is changingdistribution of pika and how it is changing.

• GEOSS infrastructure perspective: to investigate the to investigate the interoperability process to determine valuable predictors for the interoperability process to determine valuable predictors for the impact of climate change on biodiversityimpact of climate change on biodiversity

• Use observations of pika over the last 20 years, plus existing modeling demonstration systems, to model pika distributions to model pika distributions and how they may change with climateand how they may change with climate

AIP-3 Kickoff Workshop

• Logistics– 11-12 March 2010

– Location: ESA ESRIN

– Plenary and Parallel sessions

• Objectives– Develop collaboration and interoperability goals– Develop detailed plans and schedule

– Design beyond CFP AIP Architecture

– Develop Scenarios suitable for directing development of Operational Exemplars

Reusable Process for Deploying Scenarios

• Engineering Use Cases support SBA Scenarios

• 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 Use Cases

• Use Cases: reusable service oriented architecture – Use cases for discovery, data access, etc– Utilize Interoperability Arrangements

Scenarios in AIP-3 CFP

Scenarios begun in AIP-2

• Disaster Management• Health: Air Quality

• Biodiversity and Climate Change – Prediction of an Ecosystem Evolution

• Biodiversity and Climate Change – Arctic Spatial Data Infrastructure

• Energy

Scenarios new in AIP-3

• Water – Drought• Water – Water Quality

• Extreme Precipitation

• Health and the Environment Scenario – Early Warning of Malaria
