1 High level summary and recommendations from AIP-3 George Percivall Open Geospatial Consortium Task lead AR-09-01B ADC-16, May 2011

2 AIP-3 Summary and Recommendations Improved decision-making Improved access to variety of observations Repeatable results through engineering process Increased capabilities through web services

3 AIP-3 Summary and Recommendations Improved decision-making –e.g., Global Drought Monitor Portal Improved access to variety of observations Repeatable results through engineering process Increased capabilities through web services

4 Global Drought video

5 Community of Practice: Chartered to meet Decision Support needs Community of Interest/Practices and AIP SBA/CoP Integrator Service Providers : Data, Observation, Mediation, Processing CoP Science Community GCI Community of Interest: Birds of a feather, discussion group Communities of Practices in AIP-4: -Integrated Global Water Cycle Obs. -Energy -Air Quality -Biodiversity? -Global Agricultural Monitoring? -Geohazards? SBA/CoP Integrator -Lead AIP CoP WG -Liaison from AIP to CoP -Expert in SBA science and geoinformatics -Lead application of GEOSS architecture to CoP

6 AIP-3 Summary and Recommendations Improved decision-making –e.g., Global Drought Monitor Portal Improved access to variety of observations –e.g., Climate and weather visualization in artic Repeatable results through engineering process Increased capabilities through web services

8 Arctic Scenario Wiring Diagram

9 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

10 AIP-3 Summary and Recommendations Improved decision-making –e.g., Global Drought Monitor Portal Improved access to variety of observations –e.g., Climate and weather visualization in artic Repeatable results through engineering process –e.g., Energy scenario, components, services Increased capabilities through web services

14 Energy Scenario and Use Cases (not simplified) Reference: Energy Scenario Engineering Report, GEO AIP-3, Lionel Menard, January 6, 2011.

15 AIP-3 Summary and Recommendations Improved decision-making –e.g., Global Drought Monitor Portal Improved access to variety of observations –e.g., Climate and weather visualization in artic Repeatable results through engineering process –e.g., Energy scenario, components, services Increased capabilities through web services –e.g., e-Habitat web processing and semantics

17 eHabitat Wiring Diagram

18 eHabitat Interoperability Arrangements OGC CSW ISO AP, published by the EuroGEOSS Discovery Broker OGC WPS, published by the eHabitat processing service OGC WCS 1.0.0, published by the climate change and environmental data provider W3C SPARQL, published by the GENESIS SKOS repository OpenSearch interface (with geo, temporal and semantic extensions), published by the EuroGEOSS DAC

20 AIP Use Cases

21 AIP-3 Summary and Recommendations Improved decision-making –e.g., Global Drought Monitor Portal Improved access to variety of observations –e.g., Climate and weather visualization in artic Repeatable results through engineering process –e.g., Energy scenario, components, services Increased capabilities through web services –e.g., e-Habitat web processing and semantics

22 Additional Technical topics in AIP-3 Semantics Web Processing Services Uncertainty handling Data Harmonization Data Sharing Guidelines Need for CoP Integrator role

23 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

24 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

25 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

26 GEOSS Information framework GEOSS SoA Information Viewpoint

27 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

28 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 ADC, SIF, AIP, CoPs
