1. Flood hazard maps and Flood risk maps (Guidance and Schema)
FD Drafting Group, Meeting June 2011
Flood hazard maps and Flood risk maps (Guidance and Schema)
Mette Wolstrup

2. Outline Intro to GIS Guidance document Data content and structure
Map products
Decentralised flood maps
Data exchange format
Next steps

3. Intro to GIS Guidance document
Arose from the Reporting sheet and Commission meetings
First draft – still have gaps
Section 3, As-is analysis – input from MS

4. Data content and structure
Geographic information (shape files)
- Flood scenarios (high/medium/low)
Textural information (xml)
- To be developed on the basis of the reporting sheet and the GIS guidance document

5. Map products (EU level)
Data to be used in maps
- APSFR
- Flood scenarios (high/medium/low)
- Summary data for exposed elements (e.g. population)
Data will be derived from MS submissions and other reporting streams (eg. population/landcover/EPRTR/ UWWT/WFD)

7. Map products (3) Flood scenarios/risk layers Aggregation
Flood risk population
Flood risk environment
Flood risk economic activity
International RBD
Indication of where there is data
Country
Aggregation of value for flood extents within the Country
UoM
Aggregation of value for flood extents within the UoM
APSFR*
Number of inhabitants potentially affected
Aggregation of value for flood extents within the APSFR
Flood extent
Flood extent and number of inhabitants potentially affected within certain thresholds
Flood extent and count of directly affected features
Flood extent and indication of economic activity impacted
Features
Population dataset (gridded)
IPCC installations, UWWT treatment plants, WFD protected areas
Corine land cover

8. Decentralised flood maps
List of maps Flood hazard maps showing the extent of flooding associated with the flooding scenarios (high, medium, low probability floods) Flood risk maps showing the potential adverse consequences (number of inhabitants potentially affected) Flood risk maps showing the potential adverse consequences (economic activity) Flood risk maps showing the potential adverse consequences (location of installations)

9. Decentralised flood maps (2)
Optional geographic information Areas vulnerable to floods with a high content of transported sediment and debris flows The location of other significant sources of pollution Maps with other information that Member States may consider useful Maps showing coastal areas where adequate level of protection is in place

10. Data exchange format Maps can be available through: PDF
MS National webGIS (portal)
National level web mapping service (WMS)
Will follow the INSPIRE technical guidance for MS to implement the INSPIRE View Service

11. Next Steps (DRAFT- TO BE CONFIRMED BY EMAIL)
Review period (June-August) on current document:
To be confirmed (addendum and correlation tavle with INSPIRE text) may be sent separately.
Input missing items (symbology, metadata examples etc) from first draft
Collate and respond to Member State comments and update the document accordingly
Finalise schema
Send out for second review phase at the end of August
 2. Third document update period (August-October)
Additional – presentation of guidance in mid September

12. Next Step (2) 3. After finalisation of documents (October onwards):
Start development of reporting tools (database etc)
Initiate pilot exercise for linking Member State services as a distributed system
