WIS brings new features and opportunities
• Common information exchange standards,
functions
and services for all WMO
programmes
• Inter-disciplinary discovery, retrieval and
exchange of information in real and non-real
time
• On-line catalogues using metadata based on
ISO
19100
(geographic
information
standard)
• Industry standards and off-the-shelf
hardware and software systems to ensure
cost-effectiveness and inter-operability

Structure of WIS
Functional centres:
• National Centres (NC)
• Global Information System Centres (GISC)
• Data Collection and Production Centres (DCPC)
and
• Data communication networks
WIS concerns only information exchange and data
management functions
World Meteorological Organization
6
National Centre (NC)
• Provides information collected/generated in the country to a
GISC or DCPC
• Serves as portal for national users and/or administrates their
access to WIS
• Several NCs in a country are possible (not just the NMC)
Data Collection or Production Centre (DCPC)
• Provides the programme-related
international exchange
data
&
products
for
• Supports information “Push” and ”Pull” mechanisms
• Generates, maintains, makes accessible and provides to GISCs
metadata catalogues of its data & products
World Meteorological Organization
7
Global Information System Centre (GISC)
• Receives information from NCs and DCPCs
• Exchanges information (data and metadata) with other
GISCs
• Disseminates, within its area of responsibility, the entire
set of WMO data and products for routine global
exchange
• Supports information ”Pull” mechanisms
• Generates, maintains and makes accessible metadata
catalogues of all data and products for global echange
• Ensures around-the-clock,
operations

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 Profile of
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 Implementation
o Major functions needed:






Metadata catalogues
Internet portal
Data acquisition and discovery services
Data distribution service: push and pull
Monitoring
Operational aspects like data synchronisation,
back-up, administrative issues, etc.
o To that end, work is being undertaken by
pilot projects in the different WMO
Programmes

WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES
• WIS shall provide various types of services to
meet the different requirements:
 Routine collection and dissemination service for
time-critical and operation-critical data and
products
 Data Discovery, Access and Retrieval service
 Timely delivery service for data and products
• EC “emphasized that with the sustained progress made in
its implementation, operation and upgrade, the GTS,
including satellite-based data-distribution systems and
the Improved MTN, would effectively contribute to the
WIS implementation as the core communication component
for exchange and delivery of time and operation-critical
data and products.”
World Meteorological Organization

• A) The first phase of the WIS as regards timecritical and operation-critical data is in place and
in operation: the GTS, under continuous upgrades
and improvements.
The operational data exchange service provided by
the GTS, which is currently mainly focused on
WWW requirements, will be extended to
operational requirements of other programmes as
part of the WIS;
• B) This is complemented by the further upgrade
and extension of WIS space component, so-called
IGDDS, for satellite-data distribution;
• C) The second phase, which is providing more
flexible discovery and access to all users as well as
more comprehensive data is the target for the
GISC-DCPC demonstrations and (some) preoperational implementation by end of this year.
