Services Implementation - OGC

• The Open Geospatial Consortium (OGC) proposes
  specifications for interfaces and protocols for
  GIS data management and sharing. OGC
  specifications include
• Web Map Service (WMS) ? Map services
• Web Feature Service (WFS) ? Download services
• WMS e WFS can be invoked by submitting requests
  in the form of URLs (GET/POST).

18
Services Implementation - SOA
We implement the operations offered by WMS and
WFS following OpenGIS Web Services initiative
(Service Oriented Architecture)

Conclusions (1) Where we are

• eResponse scenarios description (DL 6.5)
• Flooding in Trento, Italy
• Urban disaster in London, UK
• Supporting eResponse GIS scenario (DL 6.6)
• Organizational framework identification
• Basic GIS Services interaction description
• Services identification and design (WSDL)
• Cluster of GIS Web services design

24
Conclusions (2) Next steps

• Full implementation of the test-bed
• Basic GIS Web services implementation completion
• Further GIS Web Services identification
• Services grounding (Trento datasets and metadata)
• OpenKnowledge as user interface paradigm
• LCC interaction models completion
• Cluster of GIS Web services implementation
• Network of GIS agencies (service providers)
• Question/Answering issues
• Semantic GIS queries (e.g. Map of gasoline
  stations near Trento), semantic matching and
  query rewriting (gasoline stations ? fuel
  point ? gas_point )
