What’s
the latest in Ordnance Survey? |
We
are taking several important steps towards an enhanced
data capture, management and supply process focused
on the needs of our customers and partners. Pressing
ahead with plans for an integrated IT architecture and
data model will enable seamless data collection, storage
and management to address the growing demand for location
information. The new system will manage a greater volume
of data while enabling more efficient collection, boosting
the potential for new products while ensuring currency
and consistency between all existing datasets. We are
completing a comprehensive six-year programme of positional
accuracy improvement (PAI) affecting around 155,000
square kilometres of Great Britain. The programme was
prompted by advances in surveying technology that made
it difficult to align higher-accuracy work to rural
mapping previously surveyed at 1:2 500 scale. PAI, which
has involved extensive customer contact, is a vital
underlying element in ensuring our product portfolio
remains interoperable.
The last year has seen a large increase in the numbers
of customers and partners moving from dependency on
older large-scale products to OS MasterMap, our latest
generation of data surveyed at 1:1250. In so doing,
customer and partners gain the scope to use structured,
intelligent and well maintained geographic data as a
fully integrated business database.
Enhancements soon to be incorporated into our most highly
detailed address data – OS MasterMap Address Layer
- will add 1.3 million buildings to the spatial dataset.
Address Layer 2 will include a geographic alternative
such as the locality or district name and alias details,
such as the name of the property as well as its number
and street. Previously “non-addressable”
properties - those without letterboxes such as utilities
plant, community halls, churches and public conveniences
- will prove vital references for emergency response,
civil contingency planning, risk assessment, asset insurance,
planning, customer services and asset maintenance. Each
building will be classified as “residential”
or “commercial”, and a cross-reference table
will link our data with that of other key address providers. |
“Freedom
of Information” what do you mean by this? |
The Freedom of
Information Act (FOIA) 2000 came into law in Great Britain
in January 2005. It gives the right to any person making
a request of a public authority (including Ordnance
Survey) to be told whether it has the information they
are interested in and to have that information given
to them. The aim is to ensure there is openness and
public accountability in government activity, balanced
with the need to protect legitimate confidential information.
Since the Act came into operation, Ordnance Survey has
responded to almost 200 requests from individuals and
organisations. Government analysis has consistently
found our response rate to meet or approach 100% within
the standard statutory deadline of 20 days.
However, I want to make it clear that prior to the FOIA,
we already had an established customer contact centre
handling in excess of 2,500 enquiries per month, demonstrating
our commitment to operating within the spirit of the
legislation even before it came into force. |
Tell
us about the National GPS Network |
The National
GPS Network is an infrastructure of active and passive
Global Positioning System (GPS) reference stations enabling
surveyors to determine precise coordinates in GPS and
British National Grid spatial reference systems. Over
recent years, considerable progress has been made in
enabling the use of GPS technology within the National
Grid by defining published coordinate transformations,
most recently OSTN02.
In December 2005 we launched OS Net, a publicly available
GPS correction network, enabling up to centimetre-accuracy
data collection and a range of positioning services
both in real time and for postprocess
applications. This 90- strong base station network is
the country’s most comprehensive highaccuracy
positioning framework and has already delivered significant
efficiency improvements for our 285 field surveyors.
The network has been trialled by major utility companies,
and partners can add their technical and commercial
expertise to develop positioning applications tailored
to their customers’ requirements. This means utilities,
construction companies and other users of high-level
positioning
services no longer have to set out their own base station
network to use
centimetre- or decimetre-level GPS. Potential benefits
include cost savings in hardware, set-up and maintenance
for industries including construction, land survey and
agriculture. |
It
is said that with the services offered by the website,
you can achieve high absolute positioning accuracy throughout
Great Britain. Please elaborate. |
The
GPS website (www.gps.gov. uk) provides a coordinate
converter to transform horizontal and vertical coordinates
to ETRS89 (GPS) coordinates and vice-versa. The precise
transformations can be downloaded free of charge and
incorporated into third-party software packages. The
website also gives access to a database of passive stations
with precisely measured GPS coordinates and there is
a facility to download data from active GPS stations
for post-processing user data to improve the level of
precision.
The GPS correction network has boosted the amount of
free raw data available on the website by 90% for GPS
users including civil engineers and surveyors, asset
managers, engineers and academics.
Data from individual OS Net stations is fed to the website
directly from one central server held at our head office
rather than from each one individually. This has speeded
and streamlined the delivery of realtime data to customers,
safeguarding accuracy through direct data flow. |
How
active is private sector in the activities of Ordnance
Survey? |
As Great Britain’s national mapping agency,
Ordnance Survey operates as a public sector trading
fund which means we are financed through data licensing
rather than direct funding from the tax-payer. The
aim is to provide a sharper focus on achieving value
for money and providing key services and supplies
more effectively. Last year we returned a trading
revenue of £100.4 million. We receive more than
half of our trading revenue from the private sector
and work alongside partners and customers to develop
and deliver our products and services.
Our geographic information underpins an array of tasks
such as performance analysis, asset management, consumer
profiling, routing and supply chain management. The
accessibility and flexibility of our digital data
presents new and exciting possibilities for customers
and partners and can help inform policy and planning,
deliver improved services, join up dispar datasets
and boost process efficiencies.
Awareness and use of location information is growing
rapidly across the private sector, with GI underpinning
a growing number of services and processes across
many markets. We collaborate with a wide range of
partners and developers who evolve products and services
based on our GI. System suppliers develop data-enabling
tools, software and services to enable the management
and integration of our data.

Given
the terrorist attack last year in London, do you think
that there is a need to restrict spatial data access
to genuine users only? |
You have to understand
that Ordnance Survey information underpins £100
billion of economic activity in Great Britain every
year. That is about 8% of GDP. It is used in a vast
range of applications from educational provision to
emergency services. To restrict this information would
have a great impact on our economy. The issue is to
make sure that all our data is licensed to end users.
We will continue to highlight the benefits of GI as
location data moves further into the mainstream. As
this information is being handled by an increasing number
of people with less specialist GIS knowledge, systems
will become easier to use. Like any other data business,
we are well aware of the balance to be struck between
providing data for the legitimate user of information
and protecting society from perceived threats. Our view
is that the potential for misuse is overwhelmingly outweighed
by the tremendous benefits that our data brings to society.
Our Mapping for Emergencies scheme supplies paper map
products and GI to national organisations and emergency
services to support their response to major civil crises.
In the immediate aftermath of the London bombings, we
worked alongside other government agencies to produce
a range of wall maps, flyers and handouts incorporating
London Transport data. In the weeks that followed, we
supplied a number of organisations with full national
coverage of requested data products to inform their
contingency planning. |
