The role of graphical interfaces in the digital representation of the territory

The computer graphics and the implementation of web-based information systems have highlighted a significant field of design in which the pair form/function appears exceeded by that of usability/interaction.However, in computerized maps the usability and the functionality must take into account the image, combining logic and aesthetics.The present study deals with the digital territory representation related to the graphical users’ interfaces intended as communication surfaces: a cognitive and material space at the same time, in which usability and ergonomics are revalued in terms of visual enjoyment. They are studied in particular the graphical interfaces used in the digital representation of the territory on electronic devices.By focusing on the relationship between man and machine, they are observed the different modes of communication and interaction, analyzing the various phases and the role of design in each of them in order to understand the logic, the methods and the techniques used in the digital representation of the landscape.The paper then highlights the relationship between usability and aesthetics mediated through drawing.
