Three European steps
1. GI2000 and the EGII (European Geographic Information
Infrastructure) 1995-1999
2. ETeMII and the European Territorial Management Information
Infrastructure) 2000-2001
3. GSDI → ESDI (European spatial Data Infrastructure) → INSPIRE
(Infrastructure for Spatial Information in Europe)
2002-2003 → ???

GI2000 : a discussion paper
• An initiative born in 1995, buried in 1999
• Geographic Information in Europe: a Discussion Document, DG
XIII/E - August 1998
• Identified main barriers to development
• National orientation
• No mandate to provide for the cost of collecting and maintaining EU-
wide data sets
• Different rules exist within the Member States
• Disparities between these local markets
Page 5
GI2000 : barriers to development (cont’d)
• Lack of base data • Lack of consistency between national data sets results in lack of
exploitation for other applications, leading to duplication of effort
• Unexploited potential of GI in Europe • Lack of awareness of the potential benefits of using digital geographic
information may be the greatest barrier to future market development
• Technical problems
• Action is needed to ensure that the necessary training is available in
Europe.
Page 6
GI2000 : suggested areas for EU action
• Providing leadership for European co-operation and co-ordination • Continued support to European associations such as EUROGI,
CERCO, MEGRIN
• Stimulating the development of a European GI infrastructure • Encourage public bodies to co-operate and form partnerships with the
private sector
• Create seamless geographic base data across Europe
• Stimulate the creation of EU-wide directory services
• Ensure that GI specific standards are developed as needed
• Realising the potential of GI at European level
• Contributing to the definition of global rules and standards

A spatial data infrastructure means:
• “The availability and the unimpeded sharing and use of the
required data, according to agreed mechanisms and
specifications.”
Page 8
A spatial data infrastructure consists of:
Content
Technology
Institutional
Stake-holders
Page 9
… or about technical
In short infrastructure is…… about the existence and interoperability
and business interoperability
• of technology
• of data
• of actors

State of the art in Europe (business models)
From a 2003 EuroGeographics study on 19 European countries
(L.Aslesen and Expert-Group on Legal & Commercial Issues )
• Different categories of business models at NMAs
• with a fixed budget and tasks, all income back to government
• with a fixed budget and tasks, allowed to keep (part of) income
• with a “state contract”, often combined with an expected return on
investments for the government
Page 12
State of the art (licensing and services)
• Most cases indicate a defined policy for usage (usage rights, business license, internal/private use), and a form of license for value-added products
• However : Analysis difficult because of unclear answers
→ Language and terminology problems
• Pricing policies for on-line services fall in three main categories• Charging per volume, i.e. per hits or transaction
• Charging a fixed fee, usually per year
• Combination of these two
Page 13
Towards business ‘interoperability’
• Obvious need to increase harmonisation of (national) pricing
and licensing policies
– Doesn’t mean the same terms and prices for data anywhere
– It does mean greater agreement on pricing models, licensing
arrangements and service delivery
– And common terminology : ‘speaking the same language’

State of the art (technical)
• Results of survey (A.Jakobsson and EuroGeographics ExG-Quality)• Common Reference Data mostly available at 100%
(minimum 70% for parcels, buildings, addresses)
• At medium-high resolution (~1:10.000 scale)
• Very few implementations of international standards
• High trend in changes in DB structure:
object based (9/11), moving towards (6/5)
• Final report to be published end 2003

The INSPIRE RDM position paper :
• Identified the Common Reference Data as a key component of the
ESDI,
• And recommended• To define a conceptual model for the reference data components
• To agree of common definitions for objects and their attributes belonging to the
components of the reference data
• That reference data specifications are created and described in a way that is
commonly understood and which takes into account cultural differences.
Page 19
The 12 INSPIRE policy principles of the DPLI position paper
1- The European Spatial Data Infrastructure shall be built upon a network of National Spatial Data Infrastructures;
6- Reference data will provide the underpinning framework to which all other INSPIRE data will be referenced.
3- Datasets made available to harmonised data specifications and to common standards;
10- Harmonised licensing framework will optimise sharing and trading of georeferenced thematic information;
Page 20
The INSPIRE Common Reference Data
1. Units of administration
2. Selected topographic themes
– hydrography, transport, heights
3. . Units of property rights
– parcels, buildings.
4. Geodesy
5. Addresses
6. Orthoimages
7. Gazetteer

EuroSpec Workshop 2 (July 2003):
• Co-organised with the European Commission (JRC)
• 42 experts, from 16 countries (EU-15, EFTA, new MS)
• Representing main stakeholders
Page 24
WS-2 conclusions
• EuroSpec an indispensable and timely initiative
• A process, with short- and long-term objectives
• Necessity to relate to and link with real life use-cases and existing
relevant initiatives and projects
• Build on existing legacy from major actors
EuroGeographics as the ‘natural’ leader

Next steps for the ESDI?
• GI2000, more than 5 years ago• Had already identified the issues and proposed the appropriate actions
• INSPIRE• Had raised awareness of and promoted the ESDI vision and concepts
• Had created an stronger community of GI stakeholders
• … but no INSPIRE legal framework before 2006, 2007, ?
• Urgent needs now• From the market, the Industry
• For supporting the development of the national strategies on SDIs
Page 32
Starting now, how?
1. Use and support today existing operational structures, eg. EuroGeographics • Representing major stakeholders
• Mapping and Cadastre of 40 European countries• A network of various expertise• Permanent operational body of 5 persons (and 500.000 € core budget)
• Working in close partnership with• EUROSTAT/GISCO : the EC GI data manager• JRC/INSPIRE project : the EC GI technical support• CEN/TC287 liaison member• EUROGI : the community of the European stakeholders• EuroSDR & Agile : the European GI research community• EUREF (geodesy), EuroGeoSurveys (geology), etc
2. In parallel consider what other organisational structure should best manage the future development of the ESDI.

EuroSpec : Benefits
• For reference data custodians • Shares best practice re-engineering databases & developing new
products/services
• Provides common specifications for those not yet on the move,
• Input national/organisations culture and language specifics.
• Interoperability – business • Increasing public-private partnership (and outsourcing),
• Review business policies & processes.
• Interoperability – data • A major step towards the NSDIs and the ESDI

In conclusion : Business and technical interoperability
• Is not to be imposed from a top-down approach;
• Will not occur spontaneously;
• But requires the collaboration of the main stakeholders, in a process that takes account of each organisation’s specificity;
• The EuroSpec Programme offers one of the mechanism for this collaboration to come to reality and bring concrete results;
• More cost effective and sustainable – National & European• Embracing opportunities created by technology (OGC, etc.)
• Answers to the requirements for “semantic interoperability”
