Rilevamento e rappresentazione cartografica della variabilità spaziale dei suoli a differenti scale d'indagine: i casi studio di Monastir e del Foglio 549 Muravera

The considerable spatial variability of soils makes the possibility of making teoric models of survey and representation difficult. Nowadays, traditional surveys and others using the application of new technologies are still the best way to mark soils in a specific area. One main difference is that with the first methods, (openings of profiles, drillings, chemical analysis) is very expansive to do measurements in all the points of a particular site, and these expenditures are not sustainable by normal research centres and in general by public spending while, with the second methods there is a considerable reduction in prices. In the thesis's work the two different applied methodologies have been faced with different survey scale. In particular: with a very detailed scale the EMI (Induced ElectroMagnetism) technology has been used. This technology has the prerogative of being a forwarding method in mapping pedological variations, without any inconveniences neither to the structure nor to the dynamic character of the soil (Godwin and Miller, 2003; McBratney et al., 2003; Sommer et al., 2003). For the semi-detailed scale the area of Foglio Geologico Italia 549 - Muravera�is been chosen with a scale 1:50.000 Geopedological indications are from many executed profiles (66), and they have been used to value the spatial variability to a little scale and to represent with the Pedolandscape chart, with a scale of 1:50.000. The purpose is the management and visualization of obtained data in a synthetic way, and a geographic information system (GIS) is been predisposed to this.
