The development of Sigrian has allowed to develop regional and national territorial analyses of the characteristics of irrigation and to be able to associate, at territorial level, information relating to the irrigation sector with data referring to Hydrographic pattern, to the climatic, pedological, ecological and agricultural characteristics of the territory, to the planning of the competences in the water sector, allowing to carry out cross-analyses on the components and the characteristics of the territory in which Irrigation is practiced. The way in which the computer tool was conceived and organized allowed to overlay several layers of information on a geographic basis, to process the data by selecting and extracting directly the associated informations, according to variable criteria based on the Type of processing to be carried out and produce cartographies associated with the processing.
