INSPIRE Consultation Phase INSPIRE Data Specifications – Structure and Documents

1. INSPIRE Consultation PhaseINSPIRE Data Specifications – Structure and Documents Eionet NRC EIS Workshop EEA, 16.-17. June 2011 Darja Lihteneger

2. Outline • Bigger picture - overview of the documents • Structure of data specifications (common template) • Theme definition and scope • Details: UML model, links to other models, feature catalogue • Link to the Generic Conceptual Model (GCM) • Use cases and examples • Some of specific issues in Annex II and III data specifications • Starting: how can I find information?

3. Bigger picture - overview of the documents common basis for development INSPIRE Data Specification Development Framework Draft INSPIRE Data Specifications for Annex II and III version 2.0 24 Legal basis Proposed Changes to the Generic Conceptual Model and Encoding Guidelines INSPIRE Directive and adopted Implementing Rules (EC Regulations, EC Decision) Common aspects: Guidelines for Observations & Measurements Interoperability of spatial data sets and services (including provisions for Annex I spatial data themes Consultation phase

4. Structure of data specifications • Executive summary • 1 Scope • 2 Overview • 3 Specification scopes • 4 Identification information • 5 Data content and structure • 6 Reference systems • 7 Data quality • 8 Data-set level metadata • 9 Delivery • 10 Data capture • 11 Portrayal • Bibliography • Annex A – Abstract Test Suit • Annex B – Use Cases • Annex C … Common template - on the basis of ISO 19131 - Geographic information - Data product specifications General about specification Compact overview Theme definition and scope (what is in/out), terminology Detailed narrative description / application schema / feature catalogue Specific information for spatial object types and spatial data sets Default and specific rules for visualization (view service) Use cases / Examples / Additional Information

5. Theme definition and scope • Definition of the spatial data theme is provided in INSPIRE Directive – Annex I, II and III (it cannot be changed by the Guidelines or the Implementing Rules) • Detailed scope: Additional and more precise description of the scope of the theme is provided (Chapter 2.2 Informal description), based on: framework document D2.3, use cases, reference material, thematic input • Some DS include clear examples what is in/out of the scope • Solving overlaps: some themes are facing partially overlapping scopes which need additional harmonisation

6. Details: UML model, links to other models, feature catalogue • Chapter 5 - Data content and structure • Detailed narrative description • Includes one or more applications schemas • Basic constructs: theme specific spatial object types with properties and interrelationships • Conceptual modelling tools: UML models – class diagrams, including links between the models of different themes; base elements are defined on ISO 19xxx and Generic Conceptual Model (includes common types) • Detailed feature catalogue: for each class and association roles: definitions, descriptions, multiplicity and other elements

7. Details: UML model, links to other models, feature catalogue - example Theme AM: Link to the theme EF Description in feature catalogue in AM

8. Link to the Generic Conceptual Model (GCM) • Purpose of the GCM: to provide requirements and recommendations in particular regarding the following aspects: • INSPIRE application schemas • spatial and temporal representations of spatial objects across different levels of detail and relationships between spatial objects • unique object identifiers • reference to common spatial and temporal reference system • vocabulary • Provides the overview of data interoperability components • Defines basis for the consolidated INSPIRE UML model and common base types (spatial object types, data types)

9. Link to the Generic Conceptual Model (GCM): common rules and base types/models examples 1. Modelling spatial object life-cycle information: 2. Identifier (base type): ! Be aware of the proposed changes to the GCM! • 3. Base models: • Gazetteers • Generic network model (used in themes: Transport networks and Hydrography) • 4. New proposals to the GCM: • Use of coverage functions • Rules for geo-physical observations • Additional data types used by several themes • ….

10. Metadata INSPIRE Metadata Regulation 1205/2008 (spatial data sets, series, services) (discovery) • Metadata in data specifications: • Common metadata elements • Metadata elements for reporting data quality • Theme-specific metadata elements • Guidelines on using metadata elements defined in Regulation 1205/2008/EC, for example: • Conformity • Lineage • Temporal reference • Resource abstract • Keywords • Etc. • INSPIRE Regulation on interoperability of spatial data sets and services 1089/2010 • (metadata required for interoperability) • Coordinate Reference System • Temporal Reference System • Encoding • Topological Consistency • Character Encoding

11. Use cases and examples • Use cases: described in details in Annex B, mentioned also in other parts of the document Source: D2.6 • Use-case approach defined in the DS framework document “D2.6 Methodology for the development of data specifications” • Developed based on: survey, reference material, theme-specific and cross-theme specific use cases • Input into data specifications development (requirements) • Examples: present thematic extensions, real-world practice, explains the models

12. Some of specific issues in Annex II and III data specifications • Scope: the same spatial object (natural, geographic phenomena) might be seen from different perspectives and therefore it is in the scope of different themes • High cross-theme related INSPIRE themes: Environmental monitoring facilities, Area management & reporting units, Human health, … • General models: how to understand/use them with relation to the real data, data users and data providers • common concepts used by several themes– they should be uniquely defined through those themes! • Referencing external sources: documents, classification systems • OPEN ISSUES: issues not solved so far are specifically presented in data specifications – feedback from consultation and testing might help solving them!

13. Starting: how can I find information and understand it? • I need only an overview? • INSPIRE Definition - Executive summary - Overview • Can I find information/data that I need? In which data specification should I look? • INSPIRE Definition – Overview • Can I understand it? • Overview – Narrative description (Chapter 5) – Use cases, examples - details in UML models and feature catalogue • It is complex issues? • Identify relevant themes (definition) - Looking into different data specifications – understanding cross-theme relationships (coherent!)– understanding details

14. … To conclude … • No need to be scared of many pages • Illustrations and examples help in understanding • Additional tools and material will be available (to help searching for information, using models, …) The noblest pleasure is the joy of understanding.   Leonardo da Vinci Thank you for your attention!
