Il Pavimento della Cattedrale di Santa Maria Del Fiore a Firenze: progetto di rilievo

The floor of Florence Cathedral, result of contribution of numerous craftsmen, shows excellent decorative pattern realized through “white and stained marbles” of different provenance. The relief project, obtained by digital correction of images acquired with high resolution, allows the cataloguing of used lapideous stones and the quantification of their areal extension. The recognition of material is based on macroscopic observation and for each element a data sheet containing dimensional, classificative and conservation state’s informations is produced. For the study of the state a conservation, methods able to evaluate altimetric variations will be used. Scanner system and ortophoto are very useful for the study of planarity defects and erosion state. These methods allow to know the general state of conservation of the whole floor and, in particularly, to define the lithotypes that will need major attention, above all regarding the erosion phenomena, determined by the presence of a huge number of visitors. These information can be useful for the planning of the conservation intervention and for the a sustainable use of the Cathedral.
