Aip reusable process for deploying scenarios

AIP Reusable Process for Deploying 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 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

2 data metadata products harmonization

2) Data, Metadata & Products Harmonization

Some perspectives from GEOSS AIP


The data harmonization topic

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


Gmes data products

GMES Data Products

  • Scenarios that require cross-border and cross-theme data integration, leading to the identification of interoperability requirements in different application areas…

Modeling: do the GMES Data Products comply to user requirements & acceptance criteria ?


Inspire data usability

INSPIRE Data Usability

(GIS4EU)


Qa4eo for geo

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-06-02 (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”


Qa4eo workshop sessions 2 4

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


  • 3 data harmonization aip 3 results

    3) Data Harmonization & AIP-3 results

    An overview


    Geo task ar 09 01b architecture implementation pilot

    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, e.g., IP3, and new activities solicited through Calls for Participation (CFPs)

    “fostering interoperability arrangements and common practices for GEOSS”


    Geoss interoperability arrangements from the geoss 10 year plan reference document

    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"

    A harmonized model

    • Brings 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)

    Workflow

    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

    Contribution from GENESIS project

    Lionel Menard, Mines ParisTech


    Herv caumont ogc interoperability program team

    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: +40-50 % 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)


    Herv caumont ogc interoperability program team

    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)


    Uncertainty management issues

    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


    Energy wg findings to date

    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)
