20 INSPIRE Data Usability
(GIS4EU)

21 QA4EO for GEO QA4EO 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”

22 QA4EO Workshop Sessions 2-4
« QA4EO and GEO » assets: Quality assurance process Metrology domain to be extended towards GEO SBAs Roles for Data harmonization / Data interoperability End to end process to identify open issues QA4EO seen as a ‘badge/stamp’ first a questionnaire to assess and auto-declare conformance then possibly an audit process

23 3) Data Harmonization & AIP-3 results
An overview

24 GEO Task AR-09-01b Architecture Implementation Pilot
Develop and pilot new process and infrastructure components for the GCI and the broader GEOSS architecture Continuation 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

25 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"

26 AIP-3 Working Groups and Leaders

28 Data Sharing Use Cases for licensing conditions:
Include recommendation for metadata encoding and potential impacts to Clearinghouse and GWP Use Cases for user management Using ASTER GDEM and Disaster Management scenario as case studies Experimental implementation of Use Cases Development between May and September Testing from July/August forward

29 Data Sharing Data Access Conditions: User Management
Licenses for, and waivers of, data usage Experimenting with Creative Commons CC0, CC BY, CC BY-NC Have developed Use Cases and necessary metadata fields to be used Working towards agreement on ISO classes to use for data access conditions Begin tests in September based on Use Cases User Management User registration Discussions with UIC regarding the URR (http://www.scgcorp.com/urr) User login with single sign-on Experiment with OpenID initially Considering federated solution with minimal impact on the GCI Considering centralized solution with heavy impact on the GCI Perform trade study and publish a recommendation for a solution (Cf. also GIGAS technical report, GMES SCDA…) Two activities being pursued: Data access conditions (including licenses and waivers for data usage) Note that this has an impact on the metadata User management (including registration and log-in) Start experimenting with openID initially Note impact on GCI in case a centralized solution is adopted

30 Semantic Mediation & GCI Role
Users of GEOSS Resources Providers of GEOSS Resources SBA Issue Client Server EO Resource GCI Search Tool Clearinghouse Query Expander Concepts & Mappings Metalevels 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-3 Semantic 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.

38 Workflow Interpolation is needed to estimate the concentrations of polluants at some points of interest Interpolated concentrations are thus estimates. Estimation errors need also to be communicated. An interpolation Web Processing Service is demonstrated Several uncertainty types, like quantiles, which shall be returned, can be specified in the request

40 AIP-3 results Energy Working Group
Contribution from GENESIS project Lionel Menard, Mines ParisTech

41 AIP-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 environment Sustainability 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)

42 Scenario 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 solutions Web 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, note The 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)

43 Uncertainty management issues
The data resulting from processing are themselves used as observations It could be outputs of photovoltaic systems or environmental impact indicators In most cases, there is a need to validate (calibrate) against measurements (truth), and derive from that assessments of uncertainty The major difficulty is having confidence in the measurements, and challenge is to use them to offer EO-derived products with "known" quality

44 Energy WG findings to-date
Moved from W3C W*S to OGC W*S to leverage future use of resources Transition first dreaded by proved easier than expected Main obstacle: misunderstanding of interoperability concepts and benefits Genesis Toolbox used (including OGC WPS) will be available free of charge under open source license Process of registering community catalog into GEOSS harder than expected Issues still ongoing (harvesting demands delay, discrepancies in query results between new and old resources harvested, duplication of records, etc) Process should be improved and automated More documentation is needed Formal, long, detailed documentation as well as Short, 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
