Current situation in Great Britain• Organisations horizons are largely
their own
• Data is often isolated
• Too few examples of data linking & data sharing
• Duplication
• Few definitive datasets
• Limited success with the National initiatives, such as NGDF (now dissolved) etc
• Customers have to do too much work on data integration

Power of location• Location is an essential component of
most information [80%]
• Location underpins important government activity - this impacts upon the citizen e.g.:
• buying a house
• choosing a school
• travelling to work
• emergencies
• Location information (Ordnance Survey products and services) underpins £100 billion of national GDP [OXERA report 1999]

Implications for the future • capture once – use many times•data quality issues (all kinds)
• Currency• Consistency• Completeness• Accuracy
• enable data sharing• harmonisation within nations & beyond
• across government• across all sectors• across large regions (e.g. INSPIRE across Europe)
• need for a pragmatic approach to standards• needs to fit the “national identity”• someone has to take responsibility

A National Spatial Data Infrastructure for Great Britain• Widely recognised that a successful NSDI has to play a
leading role in:• Creating Standards;• Improving Access to, and sharing of data and;• Creating a framework of reference data – a Geospatial Data
Framework
• The Digital National Framework is providing each of these within Great Britain

The Digital National Framework
The Digital National Framework is providing a new standard for
national georeferencing frameworks, defining:
• Direct and indirect reference systems (coordinates & identifiers)
• Reference data (the base geography that links users data)
• Delivery formats (Geography Mark-up Language – GML)
• Quality
• Metadata
• Linking application data with reference data (data sharing)
• Glossary
Several components developed in conjunction
with:-

Conclusions
• An SDI is key in joining up Government and business information
• SDI must be driven by customer/user/citizen needs and take into account different business models of participants
• Development should be step by step - towards a long term vision
• The Digital National Framework is providing an SDI through pragmatic implementation of standards, access mechanisms and a comprehensive geospatial data framework
