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

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

slide7

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.
