Information


INSPIRE

� The INSPIRE process is a community initiative to build the ESDI

� support policy making in issues concerning protection of the environment

� to enable harmonisation across Europe

� through interoperable spatial data sets and services

� Guidelines for INSPIRE data specifications

� will provide a common framework

� for data interoperability

� transformation

� to enable data in local data models

� to be transformed to INSPIRE-compliant models

� Without need to re-engineer current processes

� Form foundation to INSPIRE interoperability

� to meet data providers legal obligation whilst ensuring continuity of their existing

business

Tried and Tested ™

� Schema transformation, quality evaluation and data encoding in GML3.2.1

� Reuse existing data and schemas with limited reengineering to achieve INSPIRE conformance

� Work with multiple sources across multiple themes

� Create a methodology for managing data change whilst continuously ensuring INSPIRE compliance

� Undertake impact assessments now!

� Three themes successfully tested during JRC INSPIRE Annex I data specifications testing (Cadastral Parcels, Hydrography & Transport)

� Schema transformed, quality assured and output in GML3.2.1 for multiple INSPIRE stakeholders in Belgium, Great Britain and the Netherlands

Methodology using an SDI Conformance model


ESDIN

� ESDIN (ESDI “best practice” Network)

� Evaluate the theory of INSPIRE, of integrating National SDI to provide

the ESDI.

� 19 participants led by EuroGeographics, including 10 NMCAs and 5

research institutes

� 1Spatial is only UK technology provider contributing to methodologies

and services for data quality, transformation, generalisation and edge-

matching


INSPIRE Transformation Services

� a Draft Implementing Rules (IR) for Transformation Services document

� outlines the functional requirements of an INSPIRE Transformation Service

� Technical Guidance for the implementation aspects of an INSPIRE-

compliant service to meet these requirements

� minimise any potential ambiguity or the possibility of different interpretations

� on the purpose and meanings of operations and their parameters

� within the Implementing Rules

� provide confidence that such services can be realised in a practical way

� Development of Technical Guidance for the INSPIRE Transformation

Network Service (EC JRC Contract Notice 2009/S 107-153973)

Data

Project Scope


Approach

� State Of The Art analysis for Data Model Transformation Services

� Data model transformation in Service Oriented Architecture deployments

� standards and technologies for schema description and model mapping

� existing data transformation and processing engines

� Identify key functional and non-functional requirements

� Present candidate architectures

� proposed implementation, identifying specific components,

� implementation of which will meet the requirements

� Select and justify the preferred architecture(s), describing the steps required to

implement them

� Built prototype based on the Technical Guidance

� Using Transport Networks, Hydrography and Cadastral Parcels from Partner Data Providers

� Produce a video promoting the availability and applicability of the Technical Guidance


� Transport Networks, Hydrography

and Cadastral Parcels

� Other partners EA, PRAI & IGN France
