Memorandum of understanding between Commissioners Wallstróm, Solbes, Busquin 11 April 2002
The European Sustainable Development Strategy advocates a new approach to policy-making through more coherence in the Community policies. An information base that provides detailed relevant harmonised spatial information for different policy areas and that is commonly accessible could significantly contribute to this objective. Currently, exploitation of the potential of GI is hampered by lack of standards, of data and of a coherent data policy. A Community initiative to address these difficulties could unlock a vast potential of information and information services... Standardisation of GI services would furthermore open up new ways of communication, narrowing the gap between Europe and its citizens. © 2005 by ies Hans Knoop ISO-based Integration of Geoinformation for European Spatial Data Infrastructure in Germany Riyadh, November 13, 2006

Requirements for a ESDI
A European spatial data infrastructure basically needs (strategic view) Harmonized geodetic reference Metadata for discovery of existing data Harmonized geodata and geo-services Bundle geodata and geo-services within one European portal Handle access rights and licensing policies for all users Controlling and monitoring of the implementation within the EU member states Methodology for building up a ESDI (considering process, consensus process, decision making etc.) Keep data where it is collected and maintained and make it accessible for other using geo-web services (WMS, WFS etc.) All these issues are addressed by the INSPIRE framework directive and the implementation rules Hans Knoop ISO-based Integration of Geoinformation for European Spatial Data Infrastructure in Germany Riyadh, November 13, 2006

Contribution of the AAA Model to the European SDI
Preconditions for a SDI (data modelling view) Model-driven approach for describing the data Semantic harmonization of the existing data as far as possible and sufficient (feature catalogues) Application of the ISO standards for data modelling and encoding Implementation of metadata information systems for discovery and access to the data Implementation of interoperable web services for data access distribution (ISO, OGC) Operational issues (registries etc.) Legal issues (data sharing, IPR etc.) Pricing AAA data model Hans Knoop ISO-based Integration of Geoinformation for European Spatial Data Infrastructure in Germany Riyadh, November 13, 2006

Model-driven Approach is promoted for a ESDI
Recommendations are listed in the Technical Report CEN/TR 15449 “Geographic information - Standards, specifications, technical reports and guidelines, required to implement Spatial Data Infrastructures” Unified Modelling Language (UML) Use international Standards Determine ISO-profiles for specific domains Generic Structure of the AAA data model Baseline for thematic application schemas: The AAA Basic Schema Data about data: Metadata AdV Web Services Hans Knoop ISO-based Integration of Geoinformation for European Spatial Data Infrastructure in Germany Riyadh, November 13, 2006

Components of the AFIS-ALKIS-ATKIS-Data model
Generic Structure of the AAA data model Components of the AFIS-ALKIS-ATKIS-Data model AAA basic schema as profile of ISO that specifies common used data elements (e.g. geometric primitives) UML AAA thematical schema Thematical schema xxx UML automated creation by using a tool (Rational Rose script) ALKIS feature catalogue ATKIS feature catalogue xxx- feature catalogue Data exchange interface NAS (standard based data exchange interface interface xxx Hans Knoop ISO-based Integration of Geoinformation for European Spatial Data Infrastructure in Germany Riyadh, November 13, 2006

Conclusions The AAA data model with the basic schema offers a thematic-independent and generic model framework that can be a baseline for modelling of other thematic domain data models. That will help to standardise the geoinformation in Germany. A SDI for geoinformation (not just geodata) needs an exact and transparent definition of the sharable data. Therefore the same methodology as defined with the AAA data model can be used. The AdV offers support by using the UML tools for defining the data model and deriving the data exchange interface. Specific guidelines have been published on the AdV home page. The AdV guaranties maintenance at least until 2012. The AAA data model consequently meets the requirements of a data-centric view on a SDI. INSPIRE is going to implement a similar modelling methodology based on ISO standards. The success of the AAA data model bases on the consequent use of international GI standards from ISO.

Standardization Benefits
Economic Benefits of Standardisation - Summary of results - The benefit to the national economy amounts to more than US $ 15 bn per year Standards contribute more to economic growth than patents and licences Companies that participate actively in standards work have a head start on their competitors in adapting to market demands and new technologies. Transaction costs are lower when European and International Standards are used. Research risks and development costs are reduced for companies contributing to the standardization process.
