1 Oct Standards Presentation to Council 29 January 2008

2 Oct Content 1.Standardisation and GI 2.International standards 3.European standards 4.British standards 5.INSPIRE and standards

3 Oct Standardisation & GI

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

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

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

10 Oct Who is involved in GI standards?

12 Oct International standards

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

14 Oct 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 Oct Aim of ISO/TC 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 Oct 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 Oct OGC approach Organise interoperability projects Work towards consensus Formalise OGC specifications Develop strategic business opportunities Develop strategic partnerships Promote demand for interoperable products

18 Oct 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

19 Oct ISO/TC 211 standards (1) ISO 6709: Standard representation of latitude, longitude and altitude for geographic point locations ISO Revision ISO Reference model ISO – Reference Model – Part 2: Imagery ISO/TS Conceptual schema language ISO Terminology ISO Conformance and testing ISO Profiles ISO Spatial schema ISO Temporal schema ISO Rules for application schema ISO Feature cataloguing methodology ISO Amendment ISO Spatial referencing by coordinates ISO Revision ISO Spatial referencing by geographic identifiers ISO Quality principles ISO Quality evaluation procedures ISO – Metadata ISO – Metadata – Part 2: Extensions for imagery and gridded data ISO Positioning services ISO – Portrayal ISO – Encoding ISO Revision ISO – Services ISO Amendment ISO/TR Functional standards ISO/TR Imagery and gridded data Italics = not published For the latest information look on the ISO/TC 211 website

20 Oct ISO/TC 211 standards (2) ISO/TR Qualifications and certification of personnel ISO Schema for coverage geometry and functions ISO/RS Imagery and gridded data components ISO Simple feature access ISO – Feature concepts dictionaries and registers ISO Geodetic codes and parameters ISO Web Map Server Interface ISO Imagery, gridded and coverage data framework ISO Sensor and data model for imagery and gridded data ISO Data product specification ISO Location based services reference model ISO Location based services tracking and navigation ISO Multimodal location based services for routing and navigation ISO Procedures for item registration ISO Geography Markup Language (GML) ISO Generally used profiles of the spatial schema and of similar important other schemas ISO Data quality measures ISO Metadata – XML schema implementation specification ISO Schema for moving features ISO Web Feature Service ISO Filter encoding ISO Classification Systems ISO Registry of representations of geographic point location ISO Cross-domain vocabularies ISO Location Based Services - Transfer Nodes ISO Location Based Services - Linear Referencing System

21 Oct European standards

22 Oct 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 Oct 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 –GI metadata catalogue service –e-Government

24 Oct 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.

25 Oct British standards

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

28 Oct Structure of revised standard ISO Geographic information – spatial referencing by geographic identifiers BS Spatial datasets for geographical referencing: Part 0 - General model BS Specification for a street gazetteer BS Specification for a land & property gazetteer BS Specification for a gazetteer of delivery points Annex PROWs

29 Oct INSPIRE and standards

30 Oct 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

31 Oct Standards cited in the INSPIRE General Conceptual Model (GCM) EN ISO 19101:2005, Geographic information Reference model ISO/TS 19103:2005, Geographic Information Conceptual schema language EN ISO 19107:2005, Geographic information Spatial schema EN ISO 19108:2005, Geographic information Temporal schema EN ISO 19109:2006, Geographic Information Rules for application schemas EN ISO 19110:2006, Geographic information Methodology for feature cataloguing ISO 19111:2007, Geographic Information – Spatial referencing by coordinates EN ISO 19112:2005, Geographic information Spatial referencing by geographic identifiers EN ISO 19115:2005, Geographic information Metadata ISO 19123:2003, Geographic information Schema for coverage geometry and functions OGC r3, Implementation Specification for Geographic Information - Simple feature access - Part 1: Common Architecture v1.2.0 –NOTEThis is an updated version of "EN ISO :2006, Geographic information – Simple feature access – Part 1: Common architecture" which should be revised accordingly.
