La rappresentazione cartografica e i sistemi informativi geografici. Indagini sperimentali sulla media e bassa Valle del Tronto.

The thesis proposes research in the area of representation and design which in this context are intended as means for describing and disseminating information relating to environmental heritage, landscape and urban environment. The set objective is the representation of a section of territory, that of the Tronto Valley, by means of a system for collecting, processing and organising data to be contextualised at a later date with the help of the geographic information system (GIS). The thesis was developed in stages starting from the research of what has now developed into the representation of the territory according to morphological, hydrographic, human and ecological aspects. To understand the relationships between the various data objective "real" data reduction systems were compared by means of abstraction and selection operations with the aim of trying to facilitate the systems’ overall communication capacity through thematic reduction.This complexity has been the basis of the construction process of the model and therefore of its information content. In this way territorial representation becomes the object of a formal graphical communication project - the communication of a territory is the basis of its representation! The final model is therefore the re-composition of geographical system data by means of a new computer system that is able to meet its tasks, realising a communication system that is effective in producing a graphical description of the territorial complexity therein.
