An Integrated System for Easing the Access to Georeferenced Information on the Web

The association of data of different nature to geo- graphical locations is becoming increasingly popular in a growing number of domains, including urban management, economics and social studies. Traditional geographical information systems (GIS) are pow- erful tools for processing georeferenced information, but in most cases they are still complex systems that require highly trained users for obtaining useful results. This work proposes a novel web-based architecture for hiding to the users the complexity of GIS and for allowing them to interact with the underlying spatial engine through simplified visual interfaces that take care both of the query and of the presentation phases. Such integration represents an improvement in relation to most of the previous research work focused, respectively, on easying the query or the access to resulting data. The system has been designed in collaboration with the researchers of Corila, a Consortium for the preservation of the Venice lagoon, that contributed to the definition of the system requirements.
