Abstract
Atmospheric pollution monitoring and modelling applications are fundamental tools for developing environmental policies oriented to control and possibly reduce its impact on ecosystems and human health. However, discrepancies among monitoring systems in terms of spatial and temporal differences and data availability for very different ecosystems are an important limitation in environmental management. In order to standardise protocols and procedure the EU directives (e.g. INSPIRE, Air Quality Directive) and international programs (i.e. GEOSS) have oriented the scientific community to develop advanced interoperable systems able to assure real time data analysis and dissemination within the scientific community as well as to stakeholders and policy makers. To coordinate national earth and cross-disciplinary systems for promoting GEOSS and to support INSPIRE implementation, CNR promoted the GIIDA project (Integrated and Interoperable Management of Environmental Data). Among the various working groups active within GIIDA, that on air quality is addressed develop an interoperable system for air quality information management and dissemination. The system that has been developed in the GIIDA framework is based on open-source tools compliant with European standards and oriented to develop an integrated system that facilitate data storage, data mining and visualization. In our case PostGIS, a de facto standard open source geographic database, was used for data storage. PostGIS was linked to Geoserver, a Web Map Server hosted in a Servlet Container (Tomcat), that export WMS Services with data contained in the database. GeoNetwork was used for discovering the data exported; it also offers a complete tool for adding metadata compliant to INSPIRE directive (ISO 19115, ISO 19139). Stored and discovered information is finally rendered through Intermap, a tool for WMS layer visualization exported from Geoserver. The Spatial Data Infrastructure will holds information on air quality, collected new data sets related at ground-based monitoring sites as well as at off-shore sites. It will support modelling activities and environmental assessments for different case studies aiming to evaluate the impact of atmospheric pollution on terrestrial and aquatic ecosystems and human health.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
