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.
Oct 2007

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
Oct 2007

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

21. 3. European standards
Oct 2007

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)
Oct 2007

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

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.

27. Overall purpose of BS 7666
Identifying and defining geographic objects in scope
Standardising ways of sharing and accessing information about the geographic objects
Standardising ways of addressing objects
Aiding the creation of local gazetteers
Enabling the creation of national gazetteers
To remind you of the overall purpose of BS 7666…..
It is called “spatial datasets for geographical referencing” – not the most helpful title – interestingly no-one so far has come up with a better title!
The Standard is essentially about:
- identifying and defining geographic objects in scope – up to now these have been streets and land and property units but there is no reason why the principles could not be applied to other geographic objects – rivers, railways and so on.
specifying how you reference these objects such that you can have ways of sharing and accessing information about those objects –
(However the Standard is not about what information you collect about those objects beyond that necessary to identify and describe them sufficiently to be able to find them in the real world.)
The Standard is also about standardising how you address objects – although not specifically postally addressable objects.
Finally, it is about enabling the creation of local and national gazetteers.
Oct 2007

28. Structure of revised standard
ISO 19112
Geographic information – spatial referencing
by geographic identifiers BS
Spatial datasets for
geographical referencing:
Part 0 - General model
This is the proposed structure of the revised Standard.
There is now a Part 0, the general model, which builds on the International Standard but which make it applicable to UK. This now includes the old part 3 as an Annex – Specification of Addresses.
Part 1 is still a specification for a street gazetteer but now includes PROWs – Public Rights of Way
Part 2 is still a specification for land and property gazetteers.
There is now a new Part 3 – specification for a gazetteer of delivery points – it may well be renumbered Part 5 to avoid any confusion with the old Part 3.
As you will see there is scope to create more parts if required – NSAI? BS

29. 5. INSPIRE and standards
Oct 2007

30. INSPIRE and ISO standards
Directive highlights role of international standards
INSPIRE Drafting Team used standards-based approach
Based on the ISO 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 series of International Standards as the foundation for developing data specifications
There is no comparable European set of standards
