Open Data/Specifications & FOSS
The purpose of this presentation is to increase the awareness about the advantages offered by the combined use of Open
Data, Open Specifications for geospatial and water-related data collection, storage and sharing, as well as mature FOSS projects
for the creation of interoperable Web-based information systems in the water domain
Presentation outline
• Basic Concepts:• Spatial Data Infrastrcuture SDI• Water spatial data• Open specifications: Geospatial web services
• Free and Open Source Software for water SDI• User case: POLIRISPOSTA Project (system architecture)• FOSS4G conference!

User Case
(Tools for Civil Protection to support the community affected by floods on the post event)
To build a model, tools and advanced technology solutions for thecollection, mapping and evaluation of post-flood damage data,that will be useful for all organizations involved in riskmanagement, specially the Civil Protection.
