Summary

• Goals of the Early Prototype
• Use cases and use case selection
• The scenario
• The architecture
• Conclusions
• Next Steps

3
Goals of the early prototype

• - Set up the kernel of the Nature-GIS Network
  (WMS and WFS webservices on Nature related
  data)
• - Test and prove the usability of such an
  infrastructure by creating a web application
  implementing a real life use case
• - Provide a demonstration for dissemination
• - Demonstrate some INSPIRE Principles
• Data should be collected once and maintained at
  the level where this can be done most effectively
• It should be possible to combine seamless spatial
  information from different sources across Europe
  and share it between many users and applications
• It should be possible for information collected
  at one level to be shared between all the
  different levels, detailed for detailed
  investigations, general for strategic purposes
• Geographic data should become easy to understand
  and interpret because it can be visualised within
  the appropriate context selected in a
  user-friendly way

4
Use cases

• - Have a first input before the results of the
  questionnaire survey
• - Volunteers with domain expertise provided a
  real life scenario
• - Seven use cases (University of Lulea, JRC,
  Regione Piemonte, Cemagref, GISIG, territorium
  online, University of West Hungary, )
• - From Local to Regional and European use case
• - Different kinds of use cases - Planning,
  Management, Survey, etc.

The use case handle complaints on protected
areas
Citizens
UE Parliament
Complaint
DG-ENV
Other Nature Parks ?Nature2000, LIFE ?Other

The Architecture - Data Web Services

• Complaints Database (fictive)
• Transactional Web Feature Server

• Natura 2000 sites
• Web Feature Server
• Due to legal constraints - Currently only the
  centroïds

• Transportation (roads, railway, waterways)
• Web Feature Server

7
The Architecture - Data Web Services

• Administrative Boundaries (Belgian
  Administrative entities and NUTS regions)
• Web Feature Server

• CORINE Land Cover
• Web Feature Server

• Image servers Walloon Region OrthoImagery
  (PPNC), Image2000 (LandSat)
• Web Map Server

The Architecture - Workflow

• Chaining of know web services via a Workflow
• UML Modelling
• Transformation to executable code
• Including the services into an application
• The user is guided throughout the process
• General Functionality is always available when
  viewing maps

Conclusions

• Standards in action - Interoperable SDI
• - Web Map Server
• - Web Feature Server
• - Portrayal
• - Transactions
• - Filters Spatial Filters (search nearest,
  intersect, etc.)
• - Gazetteer
• - General functionality ? Data Portal / Access
  Services
• - Specific Functionality ? Workflow/Service
  Chaining
• ? Enables Nature thematic network with
  required service/functionality

13
Next Steps...

• - Refine scenario get some input from people
  involved in the real life case
• - Get feedback from Nature-GIS partners
• - Get better datasets (the polygons for natura
  2000 sites), etc.
• - move web services to JRC and other participants
  or stakeholders

14
Next Steps...
- Adopt GML based Nature-GIS data model as an
extension of existing data models (natura2000, )
- metadata / registry / catalogue - use
return from this experience in the technical
guidelines
