The effective use of information and communication technologies (ICT) is an evolutionary trend which many countries of the European Union (EU) are currently experiencing, including Italy. In this contribution, we deal with the options of applying GRASS GIS and other Geographic Free OpenSource Software (GFOSS) in the process of informatisation of public administration (PA). The activities have been carried out on the behalf of the EU Alcotra - RiskNat strategic cross-border project, under the guidance of the Imperia Province (Liguria, Italy). The main focus is the design and creation of a geographical database (DB) for managing spatial and non spatial information, using PostgreSQL/ PostGIS, GRASS and Quantum GIS (QGIS). A few geowebservices have been published according to the OGC Web Services (OWS) standards using the GeoServer platform. INSPIRE guidelines and specifications have been implemented for the related metadata files. The aim is to enable interoperability and reuse of geographical data and services which are also inserted as a layer in the RiskNat geoportal. A digital DVD ATLAS has been created for further navigation and interrogation of the various thematic layers of the cross-border basin of Roia river, using OpenLayers.
