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
