Foundations of Map-based Web Applications - A Survey of the Use, Limits and Opportunities Offered by Digital Maps

Traditional maps are one of the oldest way to express relevant information on a locality base, as synthetic representations of reality. The traditional visualization theory of maps and the related principles used to structure spatial information can inspire the modelling of new solutions in the field of information management in web application. But, the fast and generalized spreading of digital maps, and the related production of geo-localized social media is not followed by a deep integration of map in web applications, preventing the effectiveness of digital maps in solving pressing issues like aggregation, retrieval, recommendation and presentation of spatial media. Through the analysis of key concepts of maps, this contribution addresses the foundations of map-based applications, discussing the limits of current approaches and introducing new opportunities based on deep integration between maps and applications
