EuroGeographics VisionEuroGeographics Vision

Achieve interoperability of European mapping (and other GI) data

within 10 years


The 12 INSPIRE policy principles (1)The 12 INSPIRE policy principles (1)

The European Spatial Data Infrastructure shall be built upon a network of National Spatial Data Infrastructures;

INSPIRE’s technical architecture shall be designed to meet the needs of all stakeholders;

Datasets made available to harmonised data specifications and to common standards;

Data Quality procedures to ensure fitness for purpose and use;

Discovery metadata will be made available at no charge to help users identify and locate INSPIRE datasets;

Reference data will provide the underpinning framework to which all other INSPIRE data will be referenced.


The 12 INSPIRE policy principles (2)The 12 INSPIRE policy principles (2)

Thematic data will be made available to common standards;

INSPIRE data shall be made available for access and view without charge and on harmonised terms and conditions throughout the European Union;

Sustainable funding and investment mechanisms shall be put in place and maintained by Member States;

Harmonised licensing framework will optimise sharing and trading of georeferenced thematic information;

Unimpeded flow of data and information at local, regional, national and international;

Management and organisation of INSPIRE shall be based on the principles of subsidiarity and proportionality.

The first stepHistory : GDDD since 1996‘modernisation’ in progress, synergies

with INSPIRE portal, and national initiatives


Achieving the vision : Pricing & LicensingAchieving the vision : Pricing & Licensing Rationale :

– There is no value of the harmonised data if customers are not able access and to use it

Objectives :– Create licensing terms similar enough to remove legal

obstacles to regional/European products– Comparable pricing policy - not similar prices

Issues of data access, usage and dissemination terms are considered on the same priority (if not higher) than the work on the common specifications

EuroSpec objectivesEuroSpec objectives• Develop agreed specifications (data content

and data model ) for common reference data;

• Build a community of key stakeholders (including customers, system and application developers, and other project partners) and involve them in the development and implementation testing of the specifications;


EuroSpec objectives (cont’d)EuroSpec objectives (cont’d)• Test the feasibility of implementing the

specifications through development of prototypes - “ to learn by doing”; and,

• Develop implementation guidelines for NMAs to ensure national datasets can be transformed to the European specification(s).


Scope (content)Scope (content)Common Reference Data

– Units of administration– Units of property rights (parcels, buildings)– Addresses– Selected topographic themes (hydrography,

transport, height,…)– Orthoimagery

– Gazetteer – Coordinate systems


Scope (resolution)Scope (resolution) Feature catalogue

– Scale-less

Data structure, data models– Focus on large scale (1:10.000)– Address other required scale ranges

• Medium : 1:25k ~ 1:50k• Small : 1:100k ~ 1:1M

– Options, issues• Object based, unique identifier• Connected topology, shared topology, • Edge matching• 3D, time stamp


State of the art (1)State of the art (1)Most reference data components are

available in Europe, provided by an average of 2 organisations per country

Most larger scale national ‘topographic’ databases are at scale 1:10.000

Topographic data is generally not object based, but there is a definite trend to change towards object based structures

National DBs are generally not based on international standards.
