1
Current state of European GI
infrastructures
During the 70’s and 80’s NMAs have
digitised maps
– Using existing (often national) technologies,
quite often made in house solutions
– Developing specific internal standards,
– And then contributing to independent national
standards,
– While devising national independent licensing
terms for digital data
2
Current state of European GI
infrastructures
 Digital geographic information can help develop
applications
– Pan-European: Car navigation, transportation analysis
– Cross-border: drainage basin analysis, geo-economic
analysis
 But
– Geographic information data collections comply with
varying specifications (content, structure, format, etc.)
– Access conditions vary from one country to the next
one, even from one provider to the next one
3
Implications for users
 Investigation needed to find the appropriate
suppliers
 Many negotiations under different terms to
purchase usage rights
 Need to develop tedious processes to integrate
many data sets into the targeted application
 Maintenance made further difficult
 Most turn to data brokers
 Unnecessary delays and high costs
4
Development of European
NMAs co-ordination
 1979 CERCO – European NMAs club
– Organised exchange of ideas, working groups
 first half of 90’ – MEGRIN GIE
– Development of common data bases and
projects
• SABE
• PETIT
5
SABE
 First attempt, successive editions since 1993
 Now revision 2.1 of edition 1997, soon edition 2000
(aligned with year 2000 census)
 NMAs contribute national data to the product
coordinator
 National data collections are harmonised (scale,
structure) and converted into the EUROSTAT NUTS
classification
 Product available from all NMAs plus
EuroGeographics and some distributors
 It works! But maintenance = re-create the data base
6
Geographical Data
Description Directory GDDD
 Centralised alphanumeric catalogue of NMAs
holdings, CENT TC 287 metadata compliant
 Central server designed and set up at MEGRIN
 NMAs to pass their metadata and updates
 Maintenance difficult despite recent
improvements (semi-automatic procedures)
 LaClef INFO2000 project:
– Distributed system
– Multilingual
– Customisable graphic interface
7
PETIT
 Define a pan-European 1 : 250 000 geographic
data base

User analysis
Common specification: VMap 1
Prototype evaluation
Ended end of 1999
Stalled for a while
• Many NMAs don’t maintain VMap 1 data / production line
• Too expensive for them to develop such facilities
• VMap 1 rejected by some civilian users
Revised project : EuroRegionalMap

MapBSR
Digital map of the Baltic Sea Region
 14 countries (part or full)
 Million scale
 First edition 2000
 Up-date early 2002
 NLS Finland coordinator
 Model for EuroGlobalMap
9
EuroGlobalMap
Creates a digital, seamless pan-European geographic information
collection and mechanisms for its maintenance
Adds value to the work
already done at the national level
in European National Mapping
Agencies (NMAs)

EuroGlobalMap = Significant basic part of
the European Spatial Data Infrastructure
 The EuroGlobalMap database will be the first harmonised
and seamless European wide digital geographic
information database covering almost 40 countries
 …and to have such a large amount of data themes

Names – including an European wide gazetteer of place
names, in each official national native version and an
English-like transcription.
EuroGlobalMap
One seamless data base for the whole of
Europe
European wide common licensing and
pricing policy
– geared towards high volume dissemination
and uncomplicated commercial re-use by
the private sector
A model for best practises for providing
public sector information for Europe
Spread of knowledge and new
technologies to the non-Member partners
13
EuroRegionalMap
One step further in scale
 Incremental development of high quality pan-European
vector database at medium scale (1/250K),
 Multifunctional data base, suitable for spatial analysis
and as a geographic backdrop for visualisation
 Starting with:
• 6 NMAs producing a core dataset covering France, Germany,
Belgium, Luxembourg, Denmark, Ireland and Northern Ireland in a
demonstration phase supported by the EU within its eContent
program.
• Issues on technical data harmonization, data pricing and licensing
policy and data distribution over the Internet will be solved during
this demonstration stage.

EuroRegionalMap Approach
 Incremental development
To establish a European harmonisation of NDB by mean
of a pragmatic approach through a step by step
convergence, but not by a one time effort to the high
quality final product.
 Further decentralised
– Harmonisation at the national level
– Again based on agreed border lines, as a first
productions step
– With shared quality control procedures
– And maintenance at the national level
15
EuroRegionalMap development
 Started in January 2002
 April 2002 - A prototype available
on Web Site, in user testing phase
 September 2003 - Launching the
feasibility of the extension to Europe
 February 2003 - The core dataset for
the six NMAs
 August 2003- Launching the dataset
on the market with a business plan
– Goal = facilitate broad dissemination
– Experiment a low price/high volume policy
+ Direct e-commerce
+ Uncomplicated and attractive licensing policy
 August 2003 - A production plan for the extension of the
EuroRegionalMap database to Europe

Invitation
To visit our Web Site and explore our prototype and give
your feedback on the quality of our data and the
usefulness of our project
http://www.eurogeographics.org/erm
You will find in the prototype section
• The prototype of around 60 km2
• The technical guides and documents
• The metadata on the prototype
• The survey
18
Some lessons learnt
 Specifications to be defined and agreed upon by means of
a mix of bottom-up and top-down approaches
– Top-down: Start with state of the art concepts and perceived user
requirements
– Bottom-up: Start with what can be made available, and test
prototypes
 Accept content variations within some limits, and gradual
convergence
 Go as decentralised as possible. Technology helps, but is
not enough
 Aim at convergence and maintenance at the ’source level’
 Take advantage of common products to practice on
common data policies
19
Road information &
EuroCountryMap
One more step: medium scales 1:10 000 down to
1:50 000
 Work on general specification
 But start with road related information
 Users requirements: beyond topographical data
Partnership with road administrations and private
sector players
20
HERDS project
 Specify a distributed information service
– Information content (road topography, road attributes,
navigation attributes)
– Access means, and distribution
– Rights, and data policies
 Implement and evaluate a prototype
 12 partners
– NMAs (from Sweden, Great-Britain, Germany, Austria,
and France),
– Road administrations (from Sweden and Denmark),
– Private sector companies (Navigation Technologies,
TeleAtlas, and Transport Verkher AG), and
– European bodies (ERTICO and EuroGeographics)
21
EuroSpec and INSPIRE
Need for large scale data interoperability
– Focus on the concept of “reference data”
– Market & customer (mobility, etc.)
– Governance & citizen (disaster management, etc.)
 EuroSpec : Common specifications

EuroGeographics strategy
 Start with small scales, and go progressively to larger
scales
 Specify by mixing bottom-up and top-down approaches
 Align with standards, normative or de facto, and join efforts
with other European initiatives/players
 Start with ready to go partners, and build up progressively
when other partners join
 Accept variations in time and across space
 Develop common data policies based on actual common
business
 Go for decentralised implementations.
Sustainable infrastructures will rely on
nationally maintained infrastructures
