The DEAFIN project (Development Agencies and their Impact Foreign on Investment direct), co-financed by the European Union in the framework of the ReciteII community programs, comes from the need to provide information and attract investments in three partner regions: the Province of Milan, the County of Vasternorrland and the Land of Bremen; all the areas are characterized by a series of small and medium enterprises and by the presence of abandoned or underexploited industrial areas.The DEAFIN project has been undertaken by a development team constituted by Telematic Solutions s.p.a., Planetek Italia and X-Gate Logistik Projekte GmbH, for the creation of a cognitive and informative tool and DEAFIN Web GIS. The tool is connected to digital maps available via Internet, in order to provide potential investors, development agencies, multinational or medium-small companies with all the useful elements to choose productive installation.
