1. Standardisation & GI Oct 2007 3

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 4

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 Oct 2007 5

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

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 7

2. International standards Oct 2007 12

ISO/TC 211 OGC ® ISO and 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 13

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 sectorspecific applications using geographic data. Oct 2007 14

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 15

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 "geoenable" 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 16

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 17

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 18
