  1. Modelling framework for INSPIRE data specifications: motivation and overview Clemens Portele (DT DS - Chair) INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008

  2. MotivationExtracts from the Directive • Article 7(1) • „Implementing rules laying down technical arrangements for the interoperability and, where practicable, harmonisation of spatial data sets and services, [...]“ • Article 3(7) • „‘interoperability’ means the possibility for spatial data sets to be combined, and for services to interact, without repetitive manual intervention, in such a way that the result is coherent and the added value of the data sets and services is enhanced“ • ... INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 2

  3. MotivationConclusion from Directive requirements • Development of a conceptual framework and specification methodology to establish a foundation that allows for interoperability / harmonisation.  DT DS • Development of data specifications for each spatial data theme. This work will be carried out based on the conceptual framework and specification methodology, based on the INSPIRE roadmap until May 2009 for Annex I themes and May 2012 for Annex II/III themes.  TWGs The development of INSPIRE Implementing Rules for interoperable / harmonised spatial data has to follow a two-step approach: INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 3

  4. INSPIRE Technical Architecture Overview INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 6

  5. Harmonisation – definitions data harmonisation process of developing harmonised data product specifications and implementing the necessary arrangements to transform spatial data to harmonised spatial data Note: The reference version of the spatial data set may either be transformed/restructured itself or it may be kept as-is and the transformation may occur on-the-fly whenever a spatial data service operating on the spatial data set is invoked. harmonised spatial data spatial data conformant to the harmonised data product specifications harmonised data product specifications set of data product specifications that support the provision of access to harmonised spatial data through spatial data services in a representation that allows for combining it with other harmonised spatial data in a coherent way Note: The harmonised data product specifications are not intended to replace or deprecate existing data specifications that are currently in use.

  6. Rules for application schemasFrom reality to geographic data • The core concept is the spatial object (feature) • A spatial object is an abstraction of a phenomenon in the real world • Every spatial object has a spatial object type. A spatial object type is a named classification of a fact of the real world Real World Sensor Wind speed measurement Water Surface „Universe of Discourse“ determines the relevant concepts Person Shop Building Boat/Ship  conceptual model („spatial object types“ with properties) INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 11

  11. INSPIRE Data Specifications will follow ISO 19131 The application schema is not enough for a data specification (cf. data harmonisation components)! INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 20

  12. Data transfer – D2.7 Guidelines for the encoding of spatial data • Specifies guidelines for the encoding of spatial data for the purpose of exchange between two systems • Data encoding of spatial objects will be specified as part of the data specifications • Data exchange is understood primarily as “access to data via services” which includes but is not limited to a download of a whole dataset  closely related to the download service INSPIRE Annex I TWG kick-off meeting - Clemens Portele - February 2008 - 23
