TECHNICAL CONFERENCE ON THE WMO INFORMATION SYSTEMSeoul, Republic of Korea, 6-8 November 2006

ISO 191xx series of geographic information standards

(Pierre Kerhervé, WMO secretariat)


Contents

• Presentation of ISO TC-211

• Generalities on ISO 191xx

• Reference models for ISO 191xx

• Application of ISO 191xx to WIS


ISO TC 211

The ISO 191xx series are developed by the ISO Technical Committee 211 including– 29 participating countries– 31 observing countries– Liaisons with 26 organizations (OGC,

CEOS, FAO, ICAO, IHB, WMO,etc.)

Generalities - ISO 19101 - Concepts


Generalities

• A main goal of the ISO 191xx series is to facilitate the interoperability of geographic information systems– i.e. ability to discover, access, understand

and use the information and tools, independently from the platform supporting them


Generalities

• Structured set of standards specifying methods, tools and services for the management of geographic information, including:

– Definition of data,

– Access to data

– Presentation of data

– Transfer between users


List of ISO 191xx


Generalities - Profiles

• Profiles: subset of one or several of the ISO 191xx standards

• ISO 19106 describes the procedures for the development of profiles and their registrations

• Extensions to the standards may be allowed

Domain reference model - feature

• Abstraction of real world phenomena or everything with a name part of the information system– Feature types, e.g. observation, forecast,

station, NMHS• Feature attributes, e.g. location of a station• Feature associations, e.g a station is operated by

an NMHS, observations are made at a station• Feature operations: to open a station


Represents


• General Feature Model (ISO 19109) is meta-model for feature catalogues (ISO 19110) including the definition and description of feature types, attributes, associations and operations

• Methodology (ISO 19126) for creating feature registers (ISO 19135)

• Guide for different information communities to share/develop compatible feature information registers with cross-referencing


Domain reference model - Application Schema

Architectural reference model

• The Architectural reference model (ISO 19101) describes the general types of services that will be provided by computer systems to manipulate geographic information and enumerates the service interfaces across which those services must interoperate (ISO 19116, 19117, 19118, 19119).

Application of ISO 191xx to WIS

• The WMO core metadata profile is based on several standards of the ISO 191xx series

• The further application of other standards of the ISO 191xx series has the potential to improve the interoperability of WIS with other GISs


Application of ISO 191xx to WIS

• CBS tasked the IPET-MI to further study the use of ISO 191xx series for WIS

• The work programme of the IPET-MI includes– study of the relevance of each standard of

the ISO 19xxx series to WIS– development of feature catalogues
