19Soil top soil moisture modeling into root zone soil moisture GMES Data ProductsScenarios that require cross-border and cross-theme data integration, leading to the identification of interoperability requirements in different application areas…Statistical data for modeling dry deposition rates of atmospheric acidifying components into forest ecosystemsSoil top soil moisture modeling into root zone soil moisture…Modeling: do the GMES Data Products comply to user requirements & acceptance criteria ?GMES MyOcean scenario considered by GIGAS
21QA4EO for GEOQA4EO was developed to meet the current and aspirational needs of the societal themes of the Group on Earth Observation (GEO)’s Global Earth Observation System of Systems (GEOSS)It was prepared as a direct response to GEO task DA (now DA-09-01a) to “Develop a GEO data quality assurance strategy”It is beginning with space-based observations, and evaluating expansion to in situ observations, taking account of existing work in this arena”
22QA4EO Workshop Sessions 2-4 « QA4EO and GEO » assets:Quality assurance processMetrology domain to be extended towards GEO SBAsRoles for Data harmonization / Data interoperabilityEnd to end process to identify open issuesQA4EO seen as a ‘badge/stamp’first a questionnaire to assess and auto-declare conformancethen possibly an audit process
233) Data Harmonization & AIP-3 results An overview
24GEO Task AR-09-01b Architecture Implementation Pilot Develop and pilot new process and infrastructure components for the GCI and the broader GEOSS architectureContinuation of existing efforts, e.g., IP3, and new activities solicited through Calls for Participation (CFPs)“fostering interoperability arrangements and common practices for GEOSS”Consistent with that, Task AR 09-01b is defined as: highlighting the development and testing of contributed components and leveraging of the GEOSS Common Infrastructure in a pilot setting exercising interoperability arrangements to serve SBAs/CoPs
25GEOSS Interoperability Arrangements - From the GEOSS 10 Year Plan Reference Document - Interoperability through open interfacesInteroperability specifications agreed to among contributing systemsAccess to data and information through service interfacesOpen standards and intellectual property rightsGEOSS adopting standards; agreed upon by consensus, preference to formal international standardsGEOSS will not require commercial or proprietary standardsMultiple software implementations compliant with the open standards should existGoal is that at least one of the implementations should be available to all implementers "royalty-free"

30Semantic Mediation & GCI Role Users of GEOSS ResourcesProviders of GEOSS ResourcesSBAIssueClientServerEO ResourceGCISearch ToolClearinghouseQuery ExpanderConcepts & MappingsMetalevels of Resource Interaction Support:Clients access data through deployed services (SIR, BPW)Users discover resources through published metadata (CSR & Clearinghouse)Communities connect through mediation between registered & mapped vocabularies (Vocabulary & Mapping Registry)EuroGEOSS broker is testing mediation in AIP-3Semantic mediation supports additional metalevels. Access requires discovery. Discovery requires matching search terms to catalogue terms. The vocabulary mapping to support term matching across communities / organizations requires registration and maintenance (inference and addition of mapping relationships) of the vocabularies used for resource description and data domains. This is a common infrastructure need just the same as registration of datasets.

33A harmonized modelBrings a consistency model between a sampling feature property (SDI World) and a coverage range type (EO World)O&M talks of chains of measurements / Observation processes (analysis, algorithms), so you can always attach metadata (using the rich quality stack from ISO TC211)

38WorkflowInterpolation is needed to estimate the concentrations of polluants at some points of interestInterpolated concentrations are thus estimates. Estimation errors need also to be communicated.An interpolation Web Processing Service is demonstratedSeveral uncertainty types, like quantiles, which shall be returned, can be specified in the request
40AIP-3 results Energy Working Group Contribution from GENESIS projectLionel Menard, Mines ParisTech
41AIP-3 Energy scenario: “Information on environmental impacts of the production, transportation and use of energy”Leader: Mines ParisTech (Poc: Lionel Menard & Isabelle Blanc)Team: GENESIS and EnerGEO consortiums (European Commission FP7 funded projects)Ecoinvent (Swiss SME)Why assessing the environmental impacts of the energy sector ?Key issues when assessing the environmental impacts of the Photovoltaic sector (Users)Worldwide demand is growing: % from 2003 to 2030 (IEA, 2005)Energy demand implies considerable pressure on the environmentSustainability of current and future energy consumptions, cross SBA concerns (Climate, Water, Ecosystems, Health)Need to assess current environmental impacts on a global and local scale: diversify sources, reduce pressure on environment.Look for the most favorable technology for PV module (Installers)Environmental performances of PV systems related to their implementation (Policy planners, Energy operators)Carbon footprint of a PV system according to its lifecycle (Policy planners, Energy operators)Environmental performances of PV systems related to their fabrication (Installers, Energy operators, Policy planners)The Energy Working Group is focused on answering key user questions with regard to assessing the environmental impacts of the Photovoltaic sector (questions listed on the right hand side of the slide)
42Scenario objectives: Provide the necessary GEOSS compatible components to answer user’s concerns Component’s list includes:OGC Web Map Service (WMS) and Web Processing Service (WPS) of:- Average annual solar irradiation (kWh/m2) (Mines ParisTech)- Environmental outputs of PV systems (Ecoinvent & Mines ParisTech)OGC CSW (Catalog Service Web) (EnerGEO)Appropriate web map (WMS) and web processing capacities (WPS) using software from the GENESIS project solutionsWeb Portal and Geodata Visualization Portlet (GUI) (GENESIS)The Energy WG is focused on answering the previous questions by providing the necessary GEOSS compatible components to answer user’ concerns.In the component list, noteThe development of a community catalog (CSW)The development of a processing service WPS (in support of revising the geoprocessing use case)The development of a portal (screen shots on next two slides)
43Uncertainty management issues The data resulting from processing are themselves used as observationsIt could be outputs of photovoltaic systems or environmental impact indicatorsIn most cases, there is a need to validate (calibrate) against measurements (truth), and derive from that assessments of uncertaintyThe major difficulty is having confidence in the measurements, and challenge is to use them to offer EO-derived products with "known" quality
44Energy WG findings to-date Moved from W3C W*S to OGC W*S to leverage future use of resourcesTransition first dreaded by proved easier than expectedMain obstacle: misunderstanding of interoperability concepts and benefitsGenesis Toolbox used (including OGC WPS) will be available free of charge under open source licenseProcess of registering community catalog into GEOSS harder than expectedIssues still ongoing (harvesting demands delay, discrepancies in query results between new and old resources harvested, duplication of records, etc)Process should be improved and automatedMore documentation is neededFormal, long, detailed documentation as well asShort, sharp, targeted simple topic videos (how to deploy your resource; how to register your resource; how to create your metadata, etc)3 key findings – self explanatory – findings shared by other working groups such as Health WG
