Title: Standards

Standards
  • Presentation to Council
  • 29 January 2008

Content
  • Standardisation and GI
  • International standards
  • European standards
  • British standards
  • INSPIRE and standards

3
  • 1. Standardisation GI

4
Standardisation
  • Activity of establishing, with regard to actual
    or potential problems, provisions for common and
    repeated use, aimed at the achievement of the
    optimum degree of order in a given context.
  • BSi

5
Types of standards
  • By function
  • Specification -requirements to be satisfied by
    product, material or process
  • Method - formalised way of doing something
  • Codes of practice - good, accepted practice
  • Guidance
  • Glossaries
  • By origin
  • De facto
  • De jure
  • Proprietary

6
What should a standard be?
  • Wanted
  • Usable
  • Used
  • Impartial
  • Beneficial
  • Up-to-date
  • Have wide application

7
Standards only become binding
  • If made mandatory in law
  • If a party contracted to work to them
  • If claim of conformance to it is made

8
How standards are produced
Industry or user community
Consensual process
For de jure standards only. The process varies be
tween different bodies
Adopt standard
Identify need for standard
Nominate members
Receive feedback Keep under review after p
ublication
Comment and response
Standards body
Technical committee
Publish Standard
Agree to issue as Standard
Consult with wider community
Adopt draft standard
Produce draft standard
Submit Work Item Proposal
Form working group

2. International standards
13
ISO and OGC
  • ISO International Organization for
    Standardisation
  • ISO TC/211 Technical Committee for Geographic
    Information/ Geomatics
  • OGC Open Geospatial Consortium Inc

14
Work of ISO/TC 211
  • Standardizing in the field of digital geographic
    information.
  • Establishing a structured set of standards for
    information concerning objects or phenomena that
    are directly or indirectly associated with a
    location relative to the Earth.
  • Specifying methods, tools and services for
  • data management (including definition and
    description),
  • data acquisition, processing and analysis
  • accessing, presenting and transferring data in
    digital form between different users, systems and
    locations.
  • Linking to appropriate standards for information
    technology and data where possible
  • Providing a framework for the development of
    sector-specific applications using geographic
    data.

15
Aim of ISO/TC 211...
  • Develop a family of international standards to
  • support the understanding and usage of GI
  • increase the availability, access, integration,
    and sharing of geographic information,
  • enable inter-operability of geospatially enabled
    computer systems
  • contribute to a unified approach to addressing
    global ecological and humanitarian problems
  • ease the establishment of geospatial
    infrastructures on local, regional and global
    level
  • contribute to sustainable development

16
Open Geospatial Consortium
  • International industry consortium of 340
    companies, government agencies and universities.

  • Consensus process to develop publicly available
    interface specifications.
  • Specifications support interoperable solutions
    that "geo-enable" the Web, wireless and
    location-based services, and mainstream IT.
  • Specifications enable technology developers to
    make spatial information and services accessible
    and useful with many types of applications.

17
OGC approach
  • Organise interoperability projects
  • Work towards consensus
  • Formalise OGC specifications
  • Develop strategic business opportunities
  • Develop strategic partnerships
  • Promote demand for interoperable products

18
Relationship ISO/TC 211 and OGC
  • Cooperative agreement between ISO/TC 211 and OGC
  • Common objectives
  • Complementary work programmes
  • Sharing resources
  • Avoidance of inconsistent standards

3. European standards
22
CEN/TC 287
  • Technical Committee of CEN (European Committee
    for Standardisation) for geographic information.

  • NEN, the Dutch standards body runs the
    Secretariat
  • The committee are
  • Producing a framework of standards for GI in
    Europe
  • Working with ISO/TC 211 to avoid duplication
  • Aim is
  • To support the consistent use of GI Europe
  • Ensure compatibility with international usage.
  • Support spatial data infrastructure (SDI)

23
CEN/TC 287 work programme
  • Adopt the ISO 19XXX standards as European
    standards
  • 22 published to date
  • Standards and profiles for European SDI
  • Identification of standards
  • Guidelines for implementers of SDI
  • Conformance testing and registers for SDI
  • Particular areas of interest
  • Web Map Service (WMS)
  • Metadata profile of ISO 19115
  • GI metadata catalogue service
  • e-Government

24
CEN/TC 287 and ISO/TC 211
  • Maintain close liaison
  • Vienna Agreement CEN and ISO aims
  • Optimal use of resources
  • Information exchange
  • Transparency of work in CEN and ISO
  • Provides for cooperation by
  • Correspondence and exchange of information
  • Mutual representation at meetings
  • Parallel approval of standards at international
    and European levels.

5. INSPIRE and standards
30
INSPIRE and ISO standards
  • Directive highlights role of international
    standards
  • INSPIRE Drafting Team used standards-based
    approach
  • Based on the ISO 19100 series because
  • Derived through a consensus process with a large
    number of information communities
  • Sufficiently complete and mature to be used e.g.
    as framework for the development of data
    specifications
  • Other SDI approaches recommend or use the ISO
    19100 series of International Standards as the
    foundation for developing data specifications
  • There is no comparable European set of standards
