Standards Presentation to Council 29 January 2008 Oct 2007

2 Content Standardisation and GI International standards
European standards British standards INSPIRE and standards Oct 2007

3 1. Standardisation & GI Oct 2007

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 Oct 2007

5 Types of standards By function: By origin:
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 Oct 2007

6 What should a standard be?
Wanted Usable Used Impartial Beneficial Up-to-date Have wide application Oct 2007

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 Oct 2007

8 How standards are produced
Industry or user community Consensual process How standards are produced For de jure standards only. The process varies between different bodies Adopt standard Identify need for standard Nominate members Receive feedback Keep under review after publication Comment and response Standards body Technical committee Publish Standard Form working group Submit Work Item Proposal Produce draft standard Adopt draft standard Consult with wider community Agree to issue as Standard Iterate Iterate Iterate Oct 2007

9 Scope of standardisation for GI
Reference models Modelling languages Terminology Conformance and testing Standardisation Georeferencing Web services Location based services Positioning services Data transfer Data content Data Access Users Models (schemas) Data specifications Feature cataloguing Quality Metadata Referencing by coords Geodetic codes and parameters Geographic identifiers Gazetteers Qualifications Certification Education Oct 2007

12 2. International standards
Oct 2007

13 ISO and OGC ISO = International Organization for Standardisation
ISO/TC 211 ISO and OGC OGC Open Geospatial Consortium, Inc ISO = International Organization for Standardisation ISO TC/211 – Technical Committee for Geographic Information/ Geomatics OGC® = Open Geospatial Consortium Inc Oct 2007

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. Oct 2007

17 OGC approach Organise interoperability projects Work towards consensus
Formalise OGC specifications Develop strategic business opportunities Develop strategic partnerships Promote demand for interoperable products Oct 2007

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 Oct 2007

19 For the latest information look on the ISO/TC 211 website http://www

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 Particular areas of interest Web Map Service (WMS) Metadata profile of ISO 19115 GI metadata catalogue service e-Government Oct 2007

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. Oct 2007

25 4. British standards Oct 2007

26 Current British Standards in scope
Standardisation Georeferencing Data content Data Access Users UK GEMINI (Metadata standard – profile of ISO 19115 Spatial datasets for geographical referencing BS 7666 Education Oct 2007

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 Specification for a street gazetteer BS Specification for a land & property gazetteer BS Specification for a gazetteer of delivery points Annex PROWs Oct 2007

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 Oct 2007
