1. Chapter 5.2 GIS Layers
John Cima

2. GIS Themes WISE layers have been grouped into themes.
Themes identified in the chapter are as follows
WISE Water Reference datasets
WISE Reference Background datasets
Water Framework Directive
State of the Environment
Urban Waste Water Treatment Directive
Bathing Waters Directive
Nitrates Directive
Drinking Water Directive
Floods Directive
Marine Strategy Directive
IPPC Directive

3. Detail in Appendix 5 The detail about the layers is in Appendix 5
A general description of the GIS layers that comprise the theme and their uses
A summary table for each layer
name,
brief description,
scale,
positional accuracy,
remarks
the relationships that exist for each layer both within a theme and across themes.
Technical data specification of the GIS layers in the theme
Based on INSPIRE Data Specification methodology document
Not available for all themes

4. Summary Table Summary table provided for each layer within a theme
Summary tables provided for
WISE Reference datasets
Background datasets
Water Framework Directive
EIONET / SoE
UWWTD
Bathing Waters
Layout based on Original WFD structure
Now includes relationship detail
accuracy and scale detail
Key attributes

5. Technical data specification
Based on INSPIRE document
WISE is the first to use the specification
Found to be a bit repetitive
Ensures good discipline and consistency
Completed for WFD, SoE, Bathing Waters and UWWTD
Other layers detail not finalised
Recommend that all future WISE layers use the approach

6. Basic concepts WISE GIS layers
All WISE GIS layers are
European water-related environmental GIS layers
Vector line, polygon or point datasets
Available through the WISE viewer.
Some WISE layers are to be made available for download
It is recognised that
For data collection an input scale of 1:250,000 or better should be a common goal
Using WISE Water Reference and Background / External datasets layers will be harmonised to enable European level analysis and dissemination
It is the responsibility of
Member States to collect and compile detailed GIS layers within WISE
EU or third parties to compile and maintain Reference, Background and External GIS layers

7. Visualisation WISE GIS layers
At a scale of 1;1,000,000
Thematic spatial polygons
E.g. RBD status (e.g. % of water bodies at risk)
Possibly displayed against the large river and lake layer to give context
At a scale of 1:250,000
E.g. RBD/Sub Unit status (e.g. % of water bodies at risk ) possibly with the main rivers and lake layer as context
Highlighted WISE water reference objects
E.g. Status (at /not at risk) using highlighted segments of Main Rivers.
Only those water bodies at risk that are visible at 1;250,000 are shown
At scale of < 1:250,000
Highlighted hydrology object
E.g. status e.g. (e.g. at risk/not at risk) using highlighted water bodies
visualisation at the scale of < 1:250,000 to be provided by the Member States through Web Mapping Services

8. Harmonisation WISE GIS layers
Object Harmonisation
Database links between objects
UWWTD Treatment Plant links to UWWTD Discharge Point
UWWTD Discharge Point links to WFD Surface Water Body
WFD Surface Water Body links to WISE Water Reference Object
Database links allow harmonisation within and across themes
Naming Harmonisation
Same objects have common name
Use WISE Water Reference names
Use Naming as defined in Chapter 5.4

9. Harmonisation WISE GIS layers
Graphical Harmonisation
Enables graphical continuity across themes
Use common scales
Use common background layers (e.g. Country Boundaries)
Define theme rules e.g. Lines.
Must not have dangles
Must not overlap
Must not intersect
Must connect to a specified line
Must touch a specified boundary or line
Must be covered by a specified boundary
Must not overlap a specified boundary

10. Chapter 5.3 Data Models

11. Applies to the same themes
Database model and data dictionary definitions
WISE Water Reference datasets
WISE Reference Background datasets
Water Framework Directive
State of the Environment
Urban Waste Water Treatment Directive
Bathing Waters Directive
Nitrates Directive
Drinking Water Directive
Floods Directive
Marine Strategy Directive
IPPC Directive
Those currently available are shown in bold

12. Detail in Appendix 6 The detail about each theme is in Appendix 6
A General Description of the theme’s Data Model and Data Dictionary
A Data Model for the theme
UML approach recommended,
Equivalent approaches acceptable e.g. Entity Models,
A Data Dictionary for the theme
Use of automatically generated documentation recommended e.g. XML
Equivalent approaches acceptable e.g. Entity Descriptions
Relationship to WISE Conceptual Data Model for the theme
Defines the relationships within themes and across themes

13. Use of hyperlinks Data Models and Data Dictionary are large documents
All Data Models and Data Dictionary are accessed via hyperlinks
Links to HTML Data Dictionaries are provided where available
Easier to use and navigate
Links to other relevant documents also provided
e.g. WFD Reporting schemas and SHAPE file templates
Documents to be held and managed within EEA Reportnet Server

14. Chapter Content
Describes the purpose of a Data Model and Data Dictionary
Provides a reference to Appendix 6
Explains the ideas behind the WISE Conceptual Data Model
Outlines the UML (Unified Modified Language) approach

15. WISE Conceptual Data Model
Purpose of WISE conceptual model
To identify the commonality and to determine the building blocks that will enable integration and harmonisation across the systems
NOT to create a single data model holding all the data

16. Building blocks of the model

17. Geographic or location objects

18. Object types and hierarchy

19. Object data

20. Building blocks - example

21. Data transformation

22. Documented within Appendix 6
To identify
The spatial objects within each theme
The conceptual building blocks associated with each spatial object
Links between spatial objects within the theme
Links between spatial objects across themes
Main uses
To document the key linkages of each spatial objects within the theme
To understand how to then integrate and use layers across themes

23. Chapter 5.5 Metadata

24. Chapter Content
Describes the purpose of metadata
Describes the concepts of ISO19115
Explains the scope of the WISE Metadata standard

25. WISE Metadata Standard
The profile is mainly based on the guidelines for metadata included within the original document “Guidance Document on Implementing the GIS Elements of the Water Framework Directive
Adapted to be in line with the draft implementing rules for metadata (Version 3) of the INSPIRE initiative.
The WISE metadata profile defines the minimum requirements for the metadata elements that have to be provided to enable the functional concepts of discovery and data usage.
Developed by Eurostat in conjunction with the WISE GIS Working Group
