UK Geographic Information Panel: Aims
• To give high-level advice to Ministers on geographic information issues
of national importance for the United Kingdom, in particular to:
– Identify the key medium to long-term geographic information
issues and advise Government through regular short reports to
Ministers;
– Encourage more effective, extensive and systematic use of
geographic information, led by the example of Government
Departments and other public bodies where appropriate;
– Facilitate a co-ordinated position on potential legislation, both
national and international, that might impact on the geographic
information market ;
– To promote a coherent approach to the management of geographic
information in the United Kingdom.
• The Panel is advisory and has no regulatory role

The United Kingdom Geographic
Information Panel
• Announced in April 2005
• Members appointed by UK Government
Ministers
• Members represent key interest groups in
government, the private sector and the wider UK
GI industry
• Secretariat provided by one of the organisations
represented (presently Ordnance Survey)

Steps towards
The Location Strategy for the United Kingdom
• June – December 2005 – Scoping study
• November 2005 - Transformational Government
strategy - reference to development of UK GI Strategy
• June 2006 – Consultancy awarded following tender
• July 2006 – Industry consultation commences
• December 2006 – Consultants’ draft completed
• January – July 2007 – Discussions with senior officials
across UK Government – draft refined
• August 2007 – renamed: “Place Matters: The Location
Strategy for the United Kingdom”
• October 2007 - Strategy submitted to Ministers

The target environment
• Standardised collection of information and
universal use of such data;
• Currently some beacons of good practice
– GI and location information being used to excellent
effect, and
– demonstrating the benefits …
but use of such analysis is far from the norm …

UK Location Strategy
Local authority service improvement
• Local authority uses road network data together
with pupil home address records and road
flow/congestion data to analyse school bus
routes
• Council saves £160,000 annually by improving
school bus services for just two secondary
schools AND gives the children a better service
Towards the

UK Location Strategy
Health and Well-being - Increasing patient
registrations
• Transient populations = low patient registration at
doctor’s surgeries
• Helping patients to register saves the NHS money.
• Registered patients more likely to visit doctor at
start of illness before it becomes acute and cost of
care increases significantly
• Address data and multiple occupancy information
combined with patient registration information
identifies addresses with no record of registered
patient.
• Targeted mail shots sent to ‘non-registered’
properties - encourage people to register with
doctor
• Targeted addresses monitored for effectiveness of
project
– Improved patient address list supports future
health campaigns and surveys
Towards the

UK Location Strategy
Water industry efficiency & service improvement
• Combining data about plant, equipment, pipes,
sewers, and other assets with mapping information.
• Return on investment real and demonstrable:
for one company alone –
– Additional income in one year of over £1m through
improved management of empty properties.
– Sustainable cut of at least £60k in operating costs through
the call centre efficiencies.
– Significant savings in time and cost in the provision of
timely & accurate asset information to field technicians.

Flooding Events – 2005 -2007
Summer 2007:
Insured losses:
~£3Bn
Uninsured losses:
~£1Bn+

Carlisle Floods: January 2005
• ‘blue area’ shows the actual Carlisle flood limit and
flooded roads
• lack of integrated data for risk analysis
• whole emergency plan coordination data was held in
the basement of the Council Offices shown in the top
right hand picture

Learning lessons from the 2007 floods:
The Pitt Review - December 2007
•
number of submissions made about the value of visual, mapbased tools that allow better spatial assessment of what is
happening on the ground.
• Potential to have pre-identified hot spots, drainage information
or vulnerabilities at ground level.
• could be used in flood planning exercises to run a range of
scenarios to help local responders better prepare
• could be used during flooding events to assess potential
impacts.
Need / opportunity:
• knowledge of what datasets are available for an area including
statistical data, and their quality – INSPIRE principle
• data collected and maintained to agreed data standards to
permit speedy integration
• scenario planning and comparative analysis of which
interventions work
• use by emergency services as the local situation changes

Adding the Statistical Component
– an update
Context …
NATIONAL STATISTICS
• Move to independence & standards
• ANALYSIS – not just “numbers”
• Neighbourhood Statistics
• Census

framework

The problem for statistics
• 4 Nations
• collect and publish for complex geographies
• rarely align
• fragility – lots of boundary change
• lack of harmonisation on naming and coding

... and use stable building brick geographies
Output Areas and Super Output Areas
Towards the
38
UK Location Strategy
Output Areas (OAs)
• designed for 2001 Census (E&W)
• output separated from collection
• synthetic blobs – around 150 population
• built automatically from unit postcodes
• approximately 175,000 OAs (E&W)
Towards the

Towards the
40
UK Location Strategy
Super Output Areas
• Groups of Output Areas – blobs built from blobs
• A three layered hierarchy
• Each layer nests within the next layer up
• Size thresholds and targets
• A new geography for collecting, aggregating and
reporting statistics

• Together with OAs will form the
core ‘atomic’ units for statistics

• Census 2011
