World Meteorological Organization


Wmo information system

WMO INFORMATION SYSTEM

Direction from WMO Congress (2003)

  • Develop:

    • Over-arching approach for solving data management problems for all WMO and related international programmes

    • A single, coordinated global infrastructure, the WMO Information System (WIS) for the collection and sharing of information

World Meteorological Organization


Reasons for wis

REASONS FOR WIS

  • Various WMO Programmes developing information systems independently

    • Incompatibilities, inefficiencies, duplication of effort and higher overall costs

  • Continued systems development in an uncoordinated manner would:

    • Exacerbate these problems

    • Increase difficulty in sharing information between programmes

    • Further isolate WMO Programmes from each other and from wider environmental community

World Meteorological Organization

Current situation: GTS

For WWW

  • GTS provides:

    • Information collection and distribution

      • Real-time push for WWW data & products(and some other programmes data)

    • Information management

      • Standard data formats

      • Implicit metadata & catalogs

World Meteorological Organization


World meteorological organization weather climate water

Current situation:

GTS and Other WMO Programmes systems

  • Information exchange

    • Multiplicity of procedures

    • Real-time and non-real-time

    • Very limited pull

  • Information management

    • Multiplicity of data formats

    • Uncoordinated/lack of metadata & catalogs

    • No discovery

WIS Vision

  • Integrated approach for all WMO Programmes

  • Routine collection and dissemination of time-critical and operation-critical data and products:

    • Real-time “push”through dedicated telecommunication

  • Data Discovery, Access and Retrieval service:

    • “Pull” through the Internet (HTTP, FTP,…)

  • Timely delivery of data and products:

    • Delayed mode “push” through dedicated telecommunication means and public data networks, especially the Internet

  • Unified procedures

    • More efficient data exchange

  • Coordinated and standardized metadata

    • Interoperability between programmes

    • Improved data management

    • ISO 191xxx series for geographic information

World Meteorological Organization


Wis brings new features and opportunities

WIS brings new features and opportunities

  • Common information exchange standards, functions and services forall WMO programmes

  • Inter-disciplinarydiscovery, retrieval and exchange of information in real-time and non-real time

  • Inter-operability through on-line catalogues usingmetadata based on ISO 19100(geographic information standard)

  • Industry standards and off-the-shelf hardware and software systems to ensurecost-effectiveness and compatibility

WIS, a key issue: interoperability

  • Interoperability enables the discovery, the retrieval and the usage of the data

    • It needs the development and the implementation of relevant Metadata standards

    • Development of a WMO Metadata Profileof the ISO 191xx series for geographic information

  • Step 1: development of the WMO Metadata Core Profile of ISO 19115 for data discovery

  • Step 2: Use of the ISO 191xx series for the access and use of the data

WIS SERVICES

WIS provide three types of services to meet the different requirements:

(1)Routine collection and dissemination service for time-critical and operation-critical data and products:

Based on real-time “push” mechanism (incl. Multicast); implemented essentially through dedicated telecommunication means with guaranteed quality of service, e.g. leased circuits, dedicated data communication network services and satellite-based data-distribution systems;

(2) Data Discovery, Access and Retrieval service:

Based on request/reply “pull” mechanism with relevant data management functions; implemented essentially through the Internet (HTTP, FTP,…);

(3)Timely delivery service for data and products:

Based on delayed mode “push” mechanism; implemented through a combination of dedicated telecommunication means and of public data networks, especially the Internet.
